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

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 application) and the new overlay material, which is typically 6 to 12 millimetres thick. If you want a decorative finish such as a stamped or stencilled pattern, the cost increases to $6,500 to $11,000 depending on the complexity of the design.

Full Replacement Costs

By comparison, removing an existing concrete driveway and pouring a new one in Nepean typically costs $12,000 to $22,000 for the same size. The major cost drivers include demolition and disposal of the old slab (concrete is heavy and expensive to haul), excavation and re-grading of the granular base, forming, pouring, and finishing the new concrete, plus the curing time required before the driveway can be used.

The Savings Are Significant

Resurfacing generally saves homeowners 50% to 65% compared to full replacement. For many Nepean properties, particularly those in established subdivisions near Merivale Road or along Woodroffe Avenue where driveways were poured 20 to 30 years ago, the concrete base is still structurally sound even though the surface looks rough.

When Resurfacing Works

Concrete resurfacing is a good option when the existing slab has surface spalling, scaling from salt exposure, or cosmetic wear but remains structurally intact. The slab should be level (not significantly heaved or settled), free of large structural cracks that go through the full depth, and properly draining. If you can walk the driveway and it feels solid underfoot with no rocking sections, resurfacing is likely viable.

When It Does Not Work

If the slab has heaved due to frost or shifted on Leda clay (common in parts of Nepean near the Rideau River corridor), resurfacing will only mask the problem temporarily. A thin overlay cannot bridge a slab that moves seasonally. Similarly, if the concrete has extensive full-depth cracking from tree root damage or base failure, the cracks will telegraph through the new surface within one or two Ottawa winters.

Ottawa Winter Performance

The bonding agent between the old slab and the new overlay is critical in our climate. Ottawa's freeze-thaw cycles, which can occur dozens of times between November and April, put enormous stress on the bond line. Contractors must use high-quality polymer-modified products rated for northern climates and ensure the existing surface is properly profiled (often by grinding or shot-blasting) to create mechanical adhesion.

Avoid having resurfacing done late in the season. The overlay needs adequate curing time before the first hard freeze, so most Ottawa contractors recommend completing the work by mid-October at the latest.
