Question 1

How do I tell if an Ottawa driveway crack is structural?

Accepted Answer

A structural crack in an Ottawa driveway is one that indicates base failure, frost heaving, or subgrade movement — not just surface-level asphalt oxidation or shrinkage. The distinction matters enormously because a surface crack can be filled and sealed, while a structural crack means the driveway underneath is failing and no amount of sealcoating or crack filler will stop the deterioration.

The clearest sign of a structural crack is displacement — when one side of the crack is higher or lower

Question 2

How long should an Ottawa asphalt patch last?

Accepted Answer

The lifespan of an asphalt patch in Ottawa depends entirely on the repair method used — professional hot-mix patches can last 10 to 15 years, while DIY cold patch typically fails within one to two winters.

Hot-mix asphalt patches applied by professionals using proper techniques represent the gold standard for permanent pothole and damage repair in Ottawa. These patches involve cutting clean, straight edges around the damaged area, removing all loose material down to stable base, applying tack c

Question 3

How do I repair a chipped corner on my Ottawa driveway?

Accepted Answer

Chipped driveway corners are extremely common in Ottawa due to snowplow damage, freeze-thaw cycling, and the heavy traffic these areas endure. The repair method depends entirely on your driveway material — asphalt, concrete, or interlock pavers each require different approaches.

For asphalt driveways, small corner chips (less than 6 inches) can be repaired with cold patch asphalt as a temporary fix, but this rarely lasts more than one Ottawa winter. The cold patch loosens during freeze-thaw cyc

Question 4

How do I lift a heaved Ottawa concrete driveway section?

Accepted Answer

Lifting a heaved concrete driveway section requires professional concrete lifting techniques — this is not a DIY repair. The heaving is caused by Ottawa's deep frost penetration (1.2-1.5 metres) pushing up sections where the base wasn't properly prepared below the frost line, or where water has infiltrated and frozen beneath the slab.

Professional concrete lifting methods include mudjacking (pumping a cement-sand slurry under the slab through drilled holes) or polyurethane foam injection (injec

Question 5

How do I fix a sunken paver in my Ottawa interlock driveway?

Accepted Answer

A sunken paver in your Ottawa interlock driveway can usually be fixed by lifting the affected pavers, adding bedding sand, re-compacting, and relaying them. This is a manageable DIY repair if only a few pavers are involved, but extensive settling indicates base problems that require professional attention.

The repair process involves removing the sunken pavers using flat pry bars or screwdrivers to lift them without damaging the edges. Once removed, you'll see the bedding sand layer beneath — t

Question 6

Can I patch a pothole in my Ottawa driveway myself?

Accepted Answer

You can patch small potholes yourself using cold patch asphalt, but this is only a temporary fix that will likely fail within one Ottawa winter. For permanent repairs, hot-mix asphalt applied by a professional is necessary, especially given Ottawa's brutal freeze-thaw cycles.

Cold patch limitations in Ottawa's climate are significant. Cold patch asphalt is designed as an emergency repair material, not a permanent solution. It's essentially asphalt mixed with cutback oils that allow it to remain

Question 7

Did my Ottawa interlock base settle or did the pavers shift on their own?

Accepted Answer

Interlock pavers don't shift on their own — what you're seeing is almost certainly base settlement beneath the pavers. Concrete pavers are heavy, stable units that stay put when properly supported, but they'll follow any movement in the base layers below.

Base settlement is extremely common in Ottawa interlock driveways, especially those installed in the last 10-15 years when many contractors cut corners on base depth to stay competitive. Ottawa's deep frost line (1.2 to 1.5 metres) and expansi

Question 8

Why is my Ottawa asphalt driveway cracking along the centre line?

Accepted Answer

Centre line cracking in your Ottawa asphalt driveway is typically caused by inadequate compaction during installation or base settlement beneath the joint where two paving passes meet. This type of cracking is structural and will worsen rapidly through Ottawa's freeze-thaw cycles if not addressed.

When asphalt driveways are paved, the material is laid in passes (strips) by the paving machine. For most residential Ottawa driveways, this means two passes that meet along the centre line of the dri

Question 9

How do I repair a sunken section in my Ottawa asphalt driveway?

Accepted Answer

A sunken section in your asphalt driveway indicates base failure beneath the surface, and proper repair requires excavating the affected area, rebuilding the base, and repaving — this is not a surface-level fix that sealcoating or patching can address.

The sunken area developed because the granular base beneath your asphalt has either washed out, settled due to poor compaction, or been compromised by water infiltration. In Ottawa's freeze-thaw climate, water penetrates through cracks in the asp

Question 10

How do I level a settled Ottawa concrete slab driveway?

Accepted Answer

Leveling a settled concrete driveway requires professional slab jacking (mudjacking) or polyurethane foam injection — this is not a DIY project. Concrete slabs settle when the base beneath them compresses or washes out, and attempting to level them with surface patching compounds will fail within one Ottawa winter.

Slab jacking is the most common method for lifting settled concrete driveways in Ottawa. A contractor drills strategic holes through the concrete slab and pumps a cement-sand-water s

Question 11

How do I prevent edge crumbling on my Ottawa asphalt driveway?

Accepted Answer

Edge crumbling on asphalt driveways is extremely common in Ottawa due to our freeze-thaw cycles, snowplow damage, and inadequate edge support during installation. The key is understanding why edges fail and implementing both immediate repairs and long-term prevention strategies.

Why Ottawa Asphalt Edges Crumble

Asphalt driveway edges are the most vulnerable part of any installation because they lack lateral support from adjacent pavement. In Ottawa's climate, this vulnerability is amplified by

Question 12

Should I be worried about thin spider lines on my new Ottawa concrete?

Accepted Answer

Thin spider-web cracks (crazing) on new concrete are cosmetic surface defects that don't affect structural integrity, but they can worsen over time in Ottawa's freeze-thaw climate if water penetrates them.

Crazing appears as fine, shallow cracks that form random patterns across the concrete surface, typically within the first few weeks after pouring. These hairline cracks only penetrate the top 3-6mm of the surface and are caused by rapid moisture loss from the concrete surface during curing, e

Question 13

How do I fix a depression after winter on my Ottawa driveway?

Accepted Answer

Depressions that appear after winter on Ottawa driveways are typically caused by base settlement, frost heaving, or water infiltration that weakened the foundation layers during freeze-thaw cycles. The repair method depends on the size, depth, and underlying cause of the depression.

Small depressions (less than 1 square metre, under 25mm deep) can often be addressed with cold patch asphalt as a temporary fix, followed by hot-mix patching in warmer weather. Clean out any loose material, apply co

Question 14

Why is my Ottawa driveway pulling away from the garage threshold?

Accepted Answer

Your driveway is pulling away from the garage threshold due to settling of the driveway base or frost heaving, both extremely common issues in Ottawa's harsh freeze-thaw climate. This gap typically develops when the driveway settles downward while the garage foundation (built on deeper footings below the frost line) remains stable.

The most likely cause is inadequate base preparation when your driveway was originally installed. Ottawa's frost line extends 1.2 to 1.5 metres deep, requiring subst

Question 15

Can I overlay scaled Ottawa concrete with a fresh thin coat?

Accepted Answer

No, you cannot successfully overlay scaled concrete with a thin coat in Ottawa's climate. Scaling (surface spalling) indicates the concrete has been damaged by freeze-thaw cycles and deicing salts, and a thin overlay will not bond properly to the compromised surface and will fail within 1-2 winters.

Why Thin Overlays Fail on Scaled Concrete

Scaling occurs when the concrete surface layer delaminates due to freeze-thaw damage, often accelerated by salt exposure. The scaled surface is weak, dusty

Question 16

How do I reseat shifted pavers in my Ottawa driveway?

Accepted Answer

Resetting shifted interlock pavers is a manageable DIY project if only a small area is affected. The key is understanding why they shifted in the first place and addressing the underlying cause, not just the surface symptoms.

Start by assessing the extent of the problem. If only a few pavers have shifted due to settling or minor base erosion, you can likely handle this yourself. However, if large sections have moved, heaved, or sunk significantly, the issue is likely deeper base failure that re

Question 17

Should I fill cracks under 1/4 inch on my Ottawa asphalt driveway?

Accepted Answer

Yes, you should fill cracks under 1/4 inch (6mm) on your Ottawa asphalt driveway. Even small cracks allow water penetration, and Ottawa's 50+ freeze-thaw cycles per winter will rapidly expand these hairline cracks into major structural damage within 1-2 seasons if left untreated.

Why small cracks matter in Ottawa's climate: Water enters even the tiniest surface cracks, freezes and expands by 9 percent, then thaws and allows more water to penetrate deeper. Each freeze-thaw cycle widens the crack

Question 18

Can I do a DIY asphalt patch on my Ottawa driveway?

Accepted Answer

You can do temporary DIY asphalt patching using cold patch material, but it won't last through Ottawa's brutal freeze-thaw cycles — expect it to loosen and fail within one to two winters. For permanent repairs, hot-mix asphalt applied by professionals is the only durable solution in Ottawa's extreme climate.

Cold patch asphalt is available at most Ottawa hardware stores and home centers for $15 to $30 per bag (covers 2 to 3 square feet at 50mm depth). It's a mixture of asphalt and aggregate tha

Question 19

Asphalt alligator cracking Ottawa fix?

Accepted Answer

Alligator cracking in Ottawa asphalt driveways indicates structural base failure and requires full removal and replacement — surface repairs will fail within one winter due to our extreme freeze-thaw cycles.

Alligator cracking (also called fatigue cracking) appears as interconnected cracks forming a pattern resembling alligator skin or chicken wire. This type of cracking signals that the asphalt has been repeatedly flexed beyond its structural capacity, typically due to inadequate base thicknes

Question 20

Crack filler for Ottawa asphalt driveway?

Accepted Answer

For Ottawa asphalt driveways, hot-pour rubberized crack filler is the only permanent solution for cracks wider than 5mm, while cold-pour crack filler works for smaller cracks but requires annual reapplication due to our extreme freeze-thaw cycles.

Ottawa's brutal winter conditions — with 50+ freeze-thaw cycles and temperatures swinging from -30°C to +35°C — make crack filling absolutely critical maintenance. Water penetrating cracks freezes and expands by 9 percent, widening the crack with ever

Question 21

Can heavy delivery trucks like concrete mixers or moving vans damage my residential driveway in Ottawa?

Accepted Answer

Yes, heavy delivery trucks can absolutely damage residential driveways in Ottawa, especially if your driveway wasn't designed for commercial vehicle loads. Most residential driveways are built for passenger vehicles and light trucks, not the concentrated axle loads from concrete mixers (up to 34,000 kg loaded), moving vans, or delivery trucks.

Asphalt driveways are particularly vulnerable because the standard residential asphalt thickness in Ottawa is typically 75-100mm total (50mm surface cour

Question 22

How much does it cost to fix driveway damage caused by a water main break in Ottawa?

Accepted Answer

Water main break driveway damage repair costs in Ottawa range from $2,000 to $15,000+ depending on the extent of damage, driveway material, and whether the city or utility covers restoration costs. The key is determining liability and understanding what restoration the responsible party will provide versus what you may need to upgrade at your own expense.

Determining Responsibility and Coverage

When a municipal water main breaks and damages your driveway, the City of Ottawa is typically respon

Question 23

What is the best way to handle the driveway-to-sidewalk transition when the City of Ottawa replaces the curb?

Accepted Answer

When the City of Ottawa replaces curbing, your driveway apron (the section between the sidewalk and road) will likely need reconstruction to match the new curb height and grade. This work must be coordinated with the city and done to municipal specifications, often requiring a separate permit and inspection.

The driveway apron sits within the municipal right-of-way and is technically city property, but homeowners are responsible for its construction and maintenance costs. When Ottawa replaces c

Question 24

How much does it cost to repair frost-heaved expansion joints in my Ottawa concrete driveway?

Accepted Answer

Repairing frost-heaved expansion joints in an Ottawa concrete driveway typically costs $15 to $40 per linear foot for professional repair, or $300 to $1,200 for an average residential driveway depending on the extent of damage and repair method required.

Frost heaving at expansion joints is extremely common in Ottawa concrete driveways due to our brutal freeze-thaw cycles and deep frost penetration. When water infiltrates the joint, freezes, and expands by 9 percent, it pushes the concrete slab

Question 25

Our asphalt driveway in Alta Vista is over 25 years old — is it worth resurfacing or should we just tear it out and start fresh?

Accepted Answer

At 25+ years old, your Alta Vista asphalt driveway is likely a candidate for full replacement rather than resurfacing, especially given Ottawa's harsh freeze-thaw conditions that accelerate asphalt deterioration.

The decision between resurfacing and replacement depends entirely on the condition of your existing base and the extent of surface damage. Resurfacing only works if the underlying base is still stable — if you're seeing widespread alligator cracking, significant settling, potholes, or

Question 26

Can Ottawa driveway repair contractors fix damage caused by a heavy delivery truck on my asphalt?

Accepted Answer

Yes, Ottawa driveway repair contractors can fix heavy truck damage to asphalt, but the repair approach depends on whether the damage is surface-level or extends into the base structure. Most residential asphalt driveways aren't designed for heavy delivery trucks, so damage often requires more than simple patching.

Surface damage like tire ruts, scuffing, or shallow gouges can typically be repaired with hot-mix asphalt patching. The contractor will cut out the damaged area in clean, straight lin

Question 27

How much does it cost to repair ruts and depressions caused by heavy truck traffic on my Ottawa driveway?

Accepted Answer

Repairing truck-caused ruts and depressions in Ottawa driveways typically costs $800 to $3,500 depending on the damage extent, repair method, and driveway material. The repair approach and cost vary significantly based on whether you have asphalt, interlock, or concrete, and how deeply the ruts have penetrated into the base layer.

Asphalt Driveway Rut Repair

For asphalt driveways, surface-level rutting (less than 25mm deep) can often be repaired with infrared patching at $8 to $15 per square f

Question 28

Can I trench under my existing asphalt driveway in Kanata to run electrical for an EV charger without repaving?

Accepted Answer

Yes, you can trench under an existing asphalt driveway to run electrical conduit for an EV charger, but it requires careful planning and professional execution to avoid damaging the driveway surface. The key is using proper trenching techniques and ensuring the trench is properly backfilled and compacted to prevent settling that could crack the asphalt above.

Trenching Methods for Existing Driveways

The most common approach is directional boring or horizontal drilling, where a specialized mach

Question 29

How much does it cost to replace just the first 10 feet of my driveway apron in Ottawa if the rest is still solid?

Accepted Answer

Replacing just the driveway apron (the first 10 feet from the street) in Ottawa typically costs $1,200 to $3,500 depending on width, material, and permit requirements. However, this work requires a City of Ottawa permit since the apron sits within the municipal right-of-way and must meet city specifications.

The driveway apron is the section between the sidewalk and the road that connects your private driveway to the municipal street. This area experiences the heaviest traffic loads from your v

Question 30

Is it worth repairing a 20-year-old asphalt driveway in Ottawa or should I just replace the whole thing?

Accepted Answer

A 20-year-old asphalt driveway in Ottawa is approaching the end of its typical lifespan, and replacement is usually the better long-term investment unless the damage is very minor and the base remains stable.

At 20 years in Ottawa's brutal climate, your driveway has endured approximately 1,000 freeze-thaw cycles, two decades of snowplow scraping, and countless applications of road salt. Most asphalt driveways built in the early 2000s are showing significant wear by now, and the question becomes

Question 31

How much does it cost to fix asphalt driveway damage caused by city snowplow berms in Ottawa?

Accepted Answer

Snowplow damage to Ottawa driveways typically costs $300 to $2,500 to repair, depending on whether you're dealing with edge cracking, surface gouging, or full-depth damage to the driveway apron. The most common damage occurs where the metal plow blade catches raised or cracked asphalt edges, tearing chunks away and creating jagged breaks that worsen rapidly through freeze-thaw cycles.

Edge damage and surface gouging represents the most frequent snowplow damage in Ottawa. When plow blades catch

Question 32

Can driveway cracks caused by Leda clay soil shifting be permanently repaired, or will they keep coming back?

Accepted Answer

Cracks caused by Leda clay shifting will keep returning unless you address the underlying soil instability — surface crack repairs are temporary band-aids that fail within 1-2 Ottawa winters when the clay moves again.

Leda clay is particularly problematic in Ottawa because it's a marine clay deposited when the Champlain Sea covered this region 10,000 years ago. This clay has unique properties that make it extremely unstable under driveways. When Leda clay gets wet, it can lose up to 80% of its

Question 33

How do Ottawa contractors fix driveway apron damage where it meets the city sidewalk?

Accepted Answer

Driveway apron repairs where the driveway meets the city sidewalk require coordination with the City of Ottawa since this area is within the municipal right-of-way, and contractors must follow specific municipal standards for materials, grading, and accessibility compliance.

The driveway apron is the section between your property line and the road surface, which includes the area adjacent to the city sidewalk. This entire zone is within the municipal right-of-way, meaning any repair work must c

Question 34

How much does it cost to repair driveway damage caused by heavy snow removal equipment in Ottawa?

Accepted Answer

Driveway damage from heavy snow removal equipment in Ottawa typically costs $300 to $3,000 to repair, depending on the extent of damage and surface material. Snowplow blade gouges in asphalt might cost $300 to $800 to patch and seal, while extensive interlock displacement or concrete edge damage can reach $2,000 to $3,000 for proper repair.

Asphalt damage is the most common issue Ottawa homeowners face after aggressive snow removal. Snowplow blades catch raised edges, existing cracks, or soft s

Question 35

Can cracked stamped concrete on my Ottawa driveway be repaired to match the original pattern and colour?

Accepted Answer

Yes, cracked stamped concrete can often be repaired to closely match the original pattern and colour, but the success depends on the crack severity, the age of the concrete, and the skill of the contractor. Minor cracks can be filled and re-textured to blend seamlessly, while major structural cracks may require partial replacement sections.

Crack injection and surface restoration is the most common repair method for stamped concrete in Ottawa. Small to moderate cracks (up to 6mm wide) can be fi

Question 36

What insurance coverage applies if my Ottawa driveway is damaged by a city snowplow or utility work?

Accepted Answer

Damage to your Ottawa driveway from city snowplows or utility work typically falls under the City of Ottawa's liability insurance, but you'll need to file a claim and prove the city's negligence — your homeowner's insurance may also provide coverage depending on your policy.

When city snowplows damage your driveway, the City of Ottawa can be held liable if you can demonstrate that the damage resulted from negligent operation rather than normal wear and tear. This includes situations where plow

Question 37

How much does it cost to replace just the driveway apron at the street in Ottawa without redoing everything?

Accepted Answer

Replacing just the driveway apron in Ottawa typically costs $800 to $2,500 depending on width, material, and permit requirements. However, this work requires a City of Ottawa permit since it's within the municipal right-of-way and must meet specific municipal standards.

The driveway apron is the section between the sidewalk and the road surface — technically part of the municipal right-of-way but the homeowner's responsibility to maintain. When this section fails (common in Ottawa due to snowpl

Question 38

How much does it cost to repair interlock pavers that sank near my foundation after heavy rain in Ottawa?

Accepted Answer

Interlock paver repair for foundation settling in Ottawa typically costs $800 to $2,500 depending on the affected area and underlying cause. The repair involves lifting settled pavers, addressing drainage issues, adding and compacting base material, and relaying the pavers with fresh polymeric sand.

Understanding Foundation Settlement Issues

When interlock pavers sink near your foundation after heavy rain, it indicates water is pooling and washing away the bedding sand beneath the pavers. This

Question 39

Is it normal for a 20-year-old asphalt driveway in Ottawa to have widespread cracking and what are my options?

Accepted Answer

Yes, widespread cracking in a 20-year-old asphalt driveway is completely normal in Ottawa's extreme climate. Most asphalt driveways here reach the end of their functional lifespan between 18-25 years, and yours is right in that window where major deterioration typically becomes apparent.

Ottawa's brutal freeze-thaw cycles are the primary culprit behind your cracking. With 50+ freeze-thaw events each winter, water penetrates small cracks, expands by 9% when it freezes, then thaws and allows even

Question 40

Is it worth repairing a driveway with settling issues in Ottawa before selling versus offering a credit?

Accepted Answer

When selling a home in Ottawa, fixing settling driveway issues typically provides better return on investment than offering a credit, especially if the settling is moderate and the base structure is sound. Most buyers will overestimate repair costs and negotiate credits that exceed actual professional repair expenses.

Settling driveway repairs in Ottawa range from $500 to $3,000 depending on the extent and cause, while buyer-demanded credits often reach $5,000 to $8,000 because buyers assume wo

Question 41

What is the cost to repair a driveway that was damaged by a large delivery truck or moving van?

Accepted Answer

Driveway damage from heavy delivery trucks or moving vans typically costs $500 to $5,000 to repair in Ottawa, depending on the extent of damage and driveway material. The most common issues are rutting in asphalt, cracked or displaced interlock pavers, and concrete surface cracking from concentrated wheel loads exceeding the driveway's design capacity.

Asphalt driveway repairs are the most frequent scenario. Heavy trucks create deep ruts, surface depressions, and sometimes punch through thin as

Question 42

How much does it cost to hire a seasonal snow removal service for my Ottawa driveway?

Accepted Answer

Snow removal services for Ottawa driveways typically cost $300 to $800 per season for residential properties, depending on driveway size, service frequency, and snowfall totals.

Most Ottawa snow removal companies offer seasonal contracts that cover the entire winter period (November through April). For an average residential driveway (40-60 square metres), expect to pay $400 to $600 per season with service triggered when snowfall reaches 5 to 8 centimetres. Larger driveways, circular drives, or

Question 43

Can concrete driveway spalling from salt damage be spot-repaired in Ottawa or does the whole slab need replacing?

Accepted Answer

Concrete spalling from salt damage can often be spot-repaired if caught early, but extensive spalling across large areas typically requires full slab replacement. The key factors are the depth of damage, percentage of surface affected, and whether the underlying concrete remains structurally sound.

Surface spalling (scaling limited to the top 5-10mm of concrete) can be successfully spot-repaired using concrete resurfacing compounds or polymer-modified repair mortars. These products bond well to

Question 44

Does home insurance cover driveway damage from a falling tree or vehicle accident in Ottawa?

Accepted Answer

Home Insurance and Driveway Damage — What's Actually Covered

The short answer is that it depends entirely on the cause of the damage and your specific policy. Home insurance in Ontario is designed to cover sudden, accidental damage from specific named perils, not gradual wear and tear. Understanding the distinction can save you from filing a claim that gets denied and potentially affects your premiums.

Scenarios That Are Typically Covered

Damage from a falling tree during a storm is generally

Question 45

How do I get asphalt patches to match the colour of my existing driveway instead of looking like black spots?

Accepted Answer

Why Patches Never Seem to Match

Fresh asphalt is jet black because the liquid asphalt binder coating the aggregate is dark and rich in oils. Over time, exposure to UV radiation, oxygen, and Ottawa's harsh weather oxidizes the binder, turning it progressively grey. A driveway that is five or more years old has lightened significantly from its original colour, so any new hot-mix patch applied to it will stand out as a conspicuous dark spot. This is purely a cosmetic issue — the patch itself is st

Question 46

My driveway was paved less than two years ago and it's already cracking — is this covered under warranty?

Accepted Answer

Understanding Driveway Paving Warranties in Ontario

Most reputable Ottawa paving contractors offer a workmanship warranty ranging from one to five years. If your driveway is showing cracks within two years of installation, you likely have grounds for a warranty claim, but the outcome depends on the type of cracking, the specific warranty terms, and whether the contractor followed proper installation practices.

What Warranties Typically Cover

A standard paving warranty covers defects in workma

Question 47

How can I fix the drainage problem on my driveway at the same time as getting cracks repaired?

Accepted Answer

Combining Drainage Fixes with Crack Repair Is Smart Planning

Addressing drainage and surface damage together is one of the most cost-effective approaches to driveway repair. Poor drainage is often the root cause of cracking in the first place — standing water seeps into small cracks, freezes during Ottawa's brutal winters, and expands to create larger damage with every freeze-thaw cycle. Fixing the cracks without solving the drainage simply sets you up for the same problems again within a year

Question 48

The city tore up part of our driveway to fix a water main and the patch job looks terrible — what can we do?

Accepted Answer

Municipal Restoration After City Work

When the City of Ottawa or a utility company excavates through your driveway for water main, sewer, or gas line work, they are legally required to restore the affected area. However, the standard of restoration often falls short of what homeowners expect. The typical municipal patch uses basic materials and meets minimum standards, which can leave your driveway with visible seams, uneven surfaces, and a patch that deteriorates faster than the surrounding dr

Question 49

How much does it cost to fix concrete driveway scaling and pitting in Ottawa?

Accepted Answer

What Causes Concrete Scaling and Pitting

Scaling is when the top layer of your concrete driveway flakes off in thin sheets, exposing the rough aggregate underneath. Pitting creates small holes or craters across the surface. Both are extremely common in Ottawa because our winters involve constant freeze-thaw cycling, heavy road salt use, and prolonged exposure to moisture from over 200cm of annual snowfall. When water penetrates the concrete surface and freezes, it expands by about 9%, physicall

Question 50

A few of my interlock driveway pavers are cracked and sunken — can I just replace those individual ones?

Accepted Answer

Yes, Individual Paver Replacement Is Possible

One of the biggest advantages of an interlock driveway is that individual pavers can be removed and replaced without disturbing the rest of the surface. If you have a handful of cracked, chipped, or sunken pavers, a targeted repair is almost always the right approach rather than redoing the entire driveway.

How the Repair Process Works

A contractor will use specialized paver extraction tools to carefully lift out the damaged pavers without chippin
