Question 1

My 30-year-old concrete driveway in Gloucester has deep heaves — is polyjacking worth trying at this age?

Accepted Answer

Polyjacking (polyurethane foam injection) can temporarily level heaved concrete sections, but on a 30-year-old driveway in Gloucester with deep heaves, you're likely looking at a short-term fix on a surface that's approaching replacement anyway.

Polyjacking works by drilling small holes through the concrete and injecting expanding polyurethane foam beneath the slab to lift and level settled or heaved sections. The process costs $8 to $15 per square foot in Ottawa and can restore a level surface

Question 2

How much does infrared asphalt patching cost compared to traditional resurfacing for an Ottawa driveway?

Accepted Answer

Infrared asphalt patching in Ottawa typically costs $8 to $15 per square foot for spot repairs, while traditional resurfacing runs $3.50 to $5.50 per square foot for the entire driveway surface. However, infrared patching is only suitable for localized repairs (potholes, small failed sections, utility cuts), not full driveway restoration.

How Infrared Asphalt Patching Works

Infrared patching uses specialized heating equipment to soften existing asphalt to 300-350°F, allowing contractors to rem

Question 3

Can my driveway be resurfaced if it has a utility trench cut running through it from a recent repair?

Accepted Answer

A utility trench cut through your driveway significantly complicates resurfacing and may require full replacement depending on how the trench was backfilled and restored. The success of resurfacing over a utility cut depends entirely on whether the trench was properly compacted with granular material or simply backfilled with loose soil.

Proper utility trench restoration involves removing the damaged asphalt, excavating the trench to stable subgrade, backfilling in compacted lifts with Granular

Question 4

Can a resurfaced driveway handle the weight of an RV or camper parked on it in Ottawa?

Accepted Answer

Whether a resurfaced driveway can handle RV weight depends entirely on the condition of the existing base underneath and the weight of your specific RV. Most asphalt overlays are only 50mm thick and rely completely on the structural integrity of what's beneath.

Understanding RV Weight and Driveway Loading

A typical travel trailer weighs 3,000 to 8,000 pounds loaded, while Class A motorhomes can exceed 30,000 pounds. More critical than total weight is the axle loading — how that weight distribu

Question 5

How much does it cost to add a stamped concrete overlay when resurfacing my Ottawa driveway?

Accepted Answer

Stamped concrete overlay for driveway resurfacing in Ottawa typically costs $8 to $14 per square foot installed, meaning $3,200 to $5,600 for an average 400 square foot driveway. This assumes your existing concrete base is structurally sound with only surface wear or minor cracking.

What's Included in Overlay Pricing

A stamped concrete overlay involves applying a 25mm to 40mm layer of polymer-modified concrete over your existing surface, then stamping decorative patterns and applying integral

Question 6

How much does polyurethane foam injection cost to level my Ottawa driveway before resurfacing?

Accepted Answer

Polyurethane foam injection (also called polyjacking or foam jacking) typically costs $8 to $15 per square foot in Ottawa for driveway leveling, making it significantly more expensive than mudjacking but faster and longer-lasting.

Polyurethane foam injection is an increasingly popular method for lifting and leveling settled concrete driveways, sunken asphalt sections, and interlock areas before resurfacing. The process involves drilling small holes (typically 16mm diameter) through the driveway

Question 7

Is spray-on asphalt resurfacing a viable option for residential driveways in Ottawa?

Accepted Answer

Spray-on asphalt resurfacing (also called chip seal or surface treatment) is generally NOT recommended for residential driveways in Ottawa. While this technique works well for rural roads and parking lots, it's poorly suited to Ottawa's extreme freeze-thaw cycles and residential driveway conditions.

What spray-on resurfacing involves: A thin layer of liquid asphalt emulsion is sprayed onto the existing surface, immediately followed by a layer of small aggregate chips. The chips are rolled into

Question 8

How much does resurfacing a stamped concrete driveway cost in Ottawa if the pattern is worn but the base is solid?

Accepted Answer

Resurfacing a stamped concrete driveway in Ottawa typically costs $8 to $16 per square foot when the base is solid but the surface pattern and colour have worn away. For an average Ottawa driveway (40-60 square metres), expect to budget $3,200 to $9,600 for professional resurfacing.

The cost depends on the resurfacing method you choose. Concrete overlay resurfacing involves applying a new 10-15mm layer of decorative concrete over the existing surface, then re-stamping the pattern and applying f

Question 9

Is it cheaper to resurface my driveway in the fall off-season in Ottawa compared to peak summer months?

Accepted Answer

Fall is actually peak paving season in Ottawa, not off-season, so you won't find cheaper pricing in September and October. In fact, fall demand often drives prices higher as contractors rush to complete projects before winter weather shuts down asphalt work.

The real "off-season" pricing opportunity in Ottawa is mid-summer (July to early August) when demand typically dips slightly. Many homeowners assume spring is ideal for paving, creating a rush in May and June, while others wait for fall's c

Question 10

How much does it cost to resurface an asphalt driveway on a rental property in Ottawa?

Accepted Answer

Asphalt driveway resurfacing in Ottawa typically costs $2,500 to $5,500 for an average residential driveway (40-60 square metres), with rental property considerations potentially affecting both timing and material choices.

Resurfacing involves applying a new 40-50mm layer of hot-mix asphalt over your existing driveway surface, assuming the current base is stable and the surface damage is limited to the top layer. This is significantly less expensive than full removal and replacement, which woul

Question 11

What is the minimum asphalt thickness when resurfacing an existing driveway in Ottawa's climate?

Accepted Answer

For asphalt resurfacing in Ottawa, the minimum thickness is 40mm (1.5 inches) compacted, though 50mm (2 inches) is strongly recommended for durability in our extreme climate.

When overlaying existing asphalt in Ottawa, thickness becomes critical because the new surface must withstand our brutal freeze-thaw cycles, heavy snow loads, and salt exposure without the benefit of a full structural rebuild. A 40mm overlay is the absolute minimum that will compact properly and provide meaningful protecti

Question 12

Can I change the colour of my Ottawa driveway when resurfacing with a new asphalt layer?

Accepted Answer

No, you cannot change the colour of your driveway with standard asphalt resurfacing. Regular hot-mix asphalt comes in only one colour — charcoal black when new, weathering to dark grey over time.

When you resurface an existing asphalt driveway in Ottawa, you're applying a new 40-50mm layer of standard HL3 surface course asphalt over the existing surface. This fresh asphalt will be the typical black colour regardless of what's underneath. The new layer completely covers the old surface, so you'l

Question 13

How does resurfacing affect the existing driveway height relative to my garage floor in Ottawa?

Accepted Answer

Resurfacing adds approximately 50mm (2 inches) to your existing driveway height, which can create a step up into your garage and potentially cause drainage issues if not properly managed.

When you resurface an asphalt driveway, the contractor applies a new layer of hot-mix asphalt directly over the existing surface. This overlay is typically 40-50mm thick after compaction — the minimum thickness needed to achieve proper compaction and durability in Ottawa's freeze-thaw climate. Thinner overlays

Question 14

How much does it cost to resurface and add a turnaround area to a long rural driveway in Kemptville?

Accepted Answer

Resurfacing and adding a turnaround to a long rural Kemptville driveway typically costs $8,000 to $18,000, depending on the driveway length, turnaround size, current condition, and material choice. Rural driveways in the Kemptville area often stretch 100 to 300 metres from the road to the house, making this a substantial project that requires careful planning and proper base preparation.

Resurfacing costs for rural driveways run $3.50 to $5.50 per square foot for asphalt overlay, assuming the e

Question 15

What are the signs that my 15-year-old driveway base has failed and resurfacing alone won't fix it in Ottawa?

Accepted Answer

Base failure in a 15-year-old Ottawa driveway shows distinct warning signs that resurfacing cannot fix — you'll see alligator cracking, rutting deeper than 25mm, edge crumbling, and sections that move or feel spongy underfoot.

The most telling sign of base failure is alligator cracking — interconnected cracks that create a pattern resembling reptile skin, typically starting in wheel tracks where loads are heaviest. This indicates the granular base has lost structural integrity and can no longer

Question 16

How much does it cost to overlay my asphalt driveway with a thin concrete topping in Ottawa?

Accepted Answer

Overlaying asphalt with concrete is not a recommended practice and is rarely done in Ottawa due to technical and durability issues. The cost would be $8-12 per square foot if attempted, but this approach creates significant problems in Ottawa's freeze-thaw climate.

Why Concrete-Over-Asphalt Overlays Don't Work in Ottawa

The fundamental issue is differential movement between materials. Asphalt remains flexible and moves with temperature changes, while concrete is rigid. In Ottawa's extreme temp

Question 17

Should I resurface my driveway before selling my house in Ottawa to increase the property value?

Accepted Answer

Resurfacing your driveway before selling can increase property value and buyer appeal, but the return on investment depends on your current driveway's condition, your home's price range, and local market conditions. In Ottawa's competitive real estate market, a well-maintained driveway creates strong curb appeal and eliminates a potential buyer objection.

When Driveway Work Adds Value

If your current driveway has significant cracking, potholes, oil stains, or faded sealcoat, addressing these i

Question 18

Can I resurface my Ottawa driveway to add a gentler slope for elderly family members?

Accepted Answer

Yes, you can resurface your Ottawa driveway to create a gentler slope, but the approach depends on your current driveway material, existing grade, and how much slope reduction you need. For elderly family members, reducing the slope from Ottawa's typical 4-6% grade to a more manageable 2-3% can significantly improve safety and accessibility.

Asphalt driveways offer the most flexibility for slope modification through resurfacing. A skilled paving contractor can apply a variable-thickness overlay

Question 19

Our rural property near Carp has a long driveway and someone suggested chip seal instead of full repaving — is that a good option?

Accepted Answer

Chip seal, also called tar-and-chip, is one of the most practical and cost-effective surfacing options for long rural driveways in the Ottawa area. If you're near Carp, Kinburn, Dunrobin, or anywhere in West Carleton, there's a good chance your neighbours have chip seal driveways already, and for good reason.

What Chip Seal Actually Is

Chip seal involves spraying a layer of hot liquid asphalt emulsion onto your existing driveway surface, then immediately spreading a layer of crushed stone chip

Question 20

How long should I wait after winter to resurface my asphalt driveway in Ottawa, and when's the best time to schedule it?

Accepted Answer

Timing your driveway resurfacing correctly in Ottawa is critical because our extreme winter-to-spring transition creates conditions that can ruin a resurfacing job if you move too quickly. The ground needs to fully stabilize before any asphalt work begins.

The Ground Must Settle First

Ottawa's frost penetrates 1.2 to 1.5 metres deep by late February. When spring arrives, the ground thaws from the top down over several weeks. During this period, the subbase under your driveway is saturated and

Question 21

What is the price per square foot to resurface different types of driveways in Ottawa right now?

Accepted Answer

Resurfacing costs in Ottawa vary significantly depending on the material, the condition of the existing surface, and the scope of preparation work required. Here is a breakdown of current pricing for the most common driveway types.

Asphalt Overlay

A standard asphalt overlay (40 to 50 millimetres of new hot-mix over the existing surface) currently costs $4.50 to $8.00 per square foot in Ottawa. The lower end applies to straightforward jobs where the existing surface is in decent condition and o

Question 22

Can I have my sunken interlock driveway pavers re-levelled instead of replacing them in Orleans?

Accepted Answer

In most cases, yes. Interlock paver re-levelling is one of the biggest advantages of a paver driveway, and it is a very common service in Orleans where many subdivisions were built on fill soil that continues to settle over time.

How Interlock Re-Levelling Works

The process involves lifting the affected pavers, adding or redistributing the bedding sand and granular base material underneath, compacting it properly, and reinstalling the same pavers. Because interlock pavers are individual units

Question 23

What type of bonding agent do Ottawa contractors use between old and new asphalt layers?

Accepted Answer

The bonding agent between old and new asphalt is a critical but often overlooked component of any Ottawa driveway resurfacing job. Without proper bonding, the new overlay can delaminate and separate from the old surface, especially under the stress of our severe winters.

Tack Coat: The Standard Bonding Agent

The most common bonding agent used by Ottawa asphalt contractors is a tack coat, which is a thin application of asphalt emulsion sprayed or brushed onto the existing surface before the new

Question 24

How long will a resurfaced asphalt driveway last in Ottawa before it needs to be done again?

Accepted Answer

The lifespan of a resurfaced asphalt driveway in Ottawa depends on several factors, but homeowners can generally expect 12 to 20 years from a properly done overlay before another resurfacing or full replacement is needed.

Factors That Determine Lifespan

Not all resurfacing jobs are equal, and the longevity of yours will depend on:

- Overlay thickness: A 50 millimetre overlay will outlast a 40 millimetre one, particularly in Ottawa where frost heaving puts constant stress on the surface. Thick

Question 25

My driveway in Kanata has alligator cracking everywhere — can it still be resurfaced or do I need a full rebuild?

Accepted Answer

Alligator cracking is one of the most telling signs of driveway distress, and whether your Kanata driveway can be resurfaced or needs a full rebuild depends on what is happening beneath the surface.

What Alligator Cracking Tells You

Alligator cracking (also called fatigue cracking) forms an interconnected pattern that resembles the skin of an alligator. Unlike simple linear cracks caused by thermal contraction, alligator cracking indicates that the structural layers beneath the surface have fa

Question 26

Is infrared asphalt repair available in Ottawa and does it actually work in cold weather?

Accepted Answer

Infrared asphalt repair is available in Ottawa and has become increasingly popular for targeted driveway resurfacing, though its effectiveness depends on conditions and the scope of the damage.

How Infrared Repair Works

Infrared repair uses a large heating panel that radiates heat onto the existing asphalt, softening it to a workable temperature (typically around 150 to 175 degrees Celsius internally) without burning the surface. Once the asphalt is pliable, the contractor rakes and re-levels

Question 27

Do contractors need to mill my old driveway before resurfacing it in Ottawa?

Accepted Answer

Milling is not always required before resurfacing, but in many Ottawa situations it is the difference between an overlay that lasts and one that fails within a few years.

What Milling Is

Milling (also called cold planing or profiling) uses a machine with a rotating drum fitted with carbide teeth to grind away a specified depth of existing asphalt. The milled surface is rough and textured, which provides an excellent bonding surface for the new overlay. The removed material is typically recycle

Question 28

How much does concrete driveway resurfacing cost in Nepean compared to pouring a new slab?

Accepted Answer

Concrete resurfacing offers Nepean homeowners a way to restore a worn driveway at a fraction of the cost of a full tear-out and pour, but the price depends on the condition of the existing slab and the type of resurfacing you choose.

Concrete Resurfacing Costs

A standard concrete resurfacing using a polymer-modified overlay on a typical Nepean driveway (40 to 50 square metres) ranges from $4,000 to $8,000. This covers surface preparation (pressure washing, crack repair, bonding agent applicati

Question 29

What thickness of asphalt overlay do Ottawa contractors recommend for a resurfaced driveway?

Accepted Answer

The thickness of an asphalt overlay is one of the most important decisions in a resurfacing project, and Ottawa's harsh climate makes it even more critical to get right.

Minimum Recommended Thickness

Most Ottawa driveway contractors recommend a minimum overlay thickness of 40 millimetres (roughly 1.5 inches) of compacted hot-mix asphalt. For driveways that see heavier traffic, such as those used by work trucks or trailers, a thickness of 50 to 65 millimetres (2 to 2.5 inches) is more appropria

Question 30

How much does an asphalt overlay cost compared to full driveway replacement in Ottawa?

Accepted Answer

An asphalt overlay is one of the most cost-effective ways to restore a worn driveway in Ottawa, and the savings compared to a full tear-out and replacement can be substantial.

Asphalt Overlay Costs in Ottawa

For a standard two-car driveway (roughly 40 to 50 square metres), an asphalt overlay typically runs between $3,500 and $6,500 in Ottawa. This includes surface preparation, a tack coat or bonding agent, and a new layer of hot-mix asphalt. By contrast, a full removal and repave of the same d
