Concrete Floor Replacement Hamilton

Q: How much does concrete floor replacement cost in Hamilton?

Concrete floor replacement Hamilton typically costs $8 to $18 per square foot for a full project including old slab removal, subgrade preparation, gravel base, vapour barrier, and new 4-inch reinforced slab. A standard 600 sq ft Hamilton basement costs $5,000 to $11,000. Cost varies based on old slab thickness and removal difficulty, required subgrade work, gravel depth needed, and finish type.

Q: Why would I need to replace my Hamilton basement concrete floor?

Hamilton basement concrete floors need replacement for several reasons: heaved or cracked slabs from frost movement, deteriorated concrete from water infiltration and freeze-thaw cycles, slabs poured too thin (less than 3 inches) that cannot support finished floor loads, floors that must be lowered as part of basement underpinning, and slabs contaminated with oil, salts, or organic material that prevent proper adhesion of floor finishes.

Q: Do I need a permit to replace my basement floor in Hamilton?

A simple concrete floor replacement without changing the finished floor elevation typically does not require a permit in Hamilton. However, if the floor replacement is part of a basement lowering, underpinning, or waterproofing project that is already permitted, the floor replacement is usually included in the existing permit. BaseWorks advises on permit requirements during the free assessment.

Q: How thick should a new Hamilton basement concrete floor be?

A new basement concrete floor Hamilton should be a minimum of 4 inches (100mm) thick for residential use. BaseWorks uses 4-inch slabs with wire mesh reinforcement or fibre reinforcement as standard. Where the floor will carry heavy point loads (steel columns, heavy equipment), thicker slabs or additional rebar are specified.

Q: How long does concrete floor replacement take in a Hamilton basement?

Concrete floor replacement Hamilton typically takes 3 to 5 days for a standard residential basement: 1 day for saw-cutting and old slab removal, 1 day for subgrade preparation and gravel, and 1 day for vapour barrier and concrete pour. The new slab needs a minimum 7-day cure before foot traffic and 28 days to full design strength before flooring installation.

Q: Can I install heated floors with a new concrete slab in Hamilton?

Yes. In-floor hydronic or electric radiant heat can be installed in a new basement concrete slab. BaseWorks coordinates with the hydronic or electrical contractor to install heating elements or tubing before the concrete pour, and ensures adequate slab thickness (typically 4.5 to 5 inches with hydronic tubing) to properly embed the system.

WHEN TO REPLACE

Signs Your Hamilton Basement Floor Needs Replacement

A lot of Hamilton basement floors were originally poured thin - 2 to 3 inches, no vapour barrier, no rebar. Decades of moisture cycling, soil movement, and freeze-thaw have left many of them cracked, heaved, or deteriorated in ways patching just can't fix. When the slab itself has failed structurally, full replacement is the only real solution.

Heave and Settlement

Sections of the floor rising or dropping unevenly points to subgrade movement or frost action - surface-level patching can't restore a slab that's already structurally failed.

Severe Cracking

Wide cracks or through-cracks letting water and radon in are usually a sign the original slab was underreinforced and has simply outlived its service life.

Post-Underpinning New Pour

After a basement gets lowered through underpinning, the old floor sits at the wrong elevation entirely - a new slab at the correct finished height is what completes the project.

Interior Waterproofing Integration

Installing an interior drain tile system means removing a strip of the floor perimeter anyway - on an already-deteriorated slab, full replacement gets a better result than patching around new drainage.

Rental Suite Upgrade

When the existing floor is too deteriorated or uneven to accept the tile, LVP, or engineered flooring a legal basement suite needs, replacement creates a flat, dry, code-compliant substrate to build on.

Radiant Heat Rough-In

In-floor hydronic or electric radiant heat has to be embedded directly in the slab - a new pour allows that integration properly, in a way a patch-over simply can't.

REPLACEMENT SEQUENCE

How BaseWorks Replaces a Hamilton Basement Concrete Floor

This follows a specific sequence, and every step matters - a properly built subgrade and vapour barrier are what determine whether the new slab lasts decades or just repeats the same problems as the old one.

Saw-Cut and Slab Removal

The old slab gets saw-cut into manageable sections, broken up with a jackhammer, and removed, with debris hauled off site and perimeter walls protected throughout.

Subgrade Inspection and Preparation

Once exposed, the subgrade soil gets inspected for soft spots, organic material, or a high water table. Any soft areas get excavated and filled with compacted granular fill, and the final subgrade is graded to the correct finished floor elevation.

Drainage Integration (if required)

If waterproofing is part of the scope, interior weeping tile goes in at footing level, with drainage components positioned before the granular base goes down.

Granular A Gravel Base

A minimum 4-inch layer of washed Granular A gravel gets compacted for uniform bearing, drainage, and a capillary break below the slab, then checked and screeded to elevation.

Vapour Barrier

A 10-mil polyethylene vapour barrier goes down, lapped a minimum of 6 inches at every seam and taped, turned up at the walls and secured - this is what stops ground moisture migrating through the slab and matters for any floor finish you'll put on top.

Concrete Pour and Finish

4 inches of 25 MPa concrete goes in with wire mesh or synthetic fibre reinforcement, screeded level, bull-floated, and finished smooth or broom depending on the flooring going on top. Control joints get cut on a 10-foot grid.

Cure Period

The new slab needs a minimum 7 days before any foot traffic, and a full 28-day cure before tile, LVP, or epoxy coating can go on top. Winter pours get protected from frost throughout that window.

COMMON QUESTIONS

Concrete Floor Replacement Hamilton FAQ

What Hamilton homeowners ask most about basement slab replacement.

How much does concrete floor replacement cost in Hamilton?

Typically $8 to $18 per square foot, covering old slab removal, subgrade preparation, gravel base, vapour barrier, and the new 4-inch reinforced slab. A standard 600 sq ft basement runs $5,000 to $11,000 all-in. Every quote is fixed-price and written, following a free site assessment.

Why would I need to replace my Hamilton basement concrete floor?

Replacement makes sense when the floor is heaved or cracked from frost movement, deteriorated from water infiltration, originally poured too thin to support a finished floor load, needs to sit at a new elevation after underpinning, or has surface contamination that prevents proper adhesion of a new finish. None of that gets fixed by patching a structurally failed slab.

Do I need a permit to replace my basement floor in Hamilton?

A straightforward floor replacement that doesn't change the finished elevation typically doesn't need its own permit. When it's part of a larger basement lowering, underpinning, or waterproofing project that's already permitted, the floor replacement usually falls under that existing permit. We'll flag exactly what applies during the free assessment.

How thick should a new Hamilton basement concrete floor be?

4 inches minimum is the standard for residential use, and that's what we build to as default, with wire mesh or fibre reinforcement included. Where the floor needs to carry heavy point loads - steel columns, heavy equipment - a thicker slab or additional rebar gets specified instead.

How long does concrete floor replacement take in a Hamilton basement?

Typically 3 to 5 days for a standard residential basement: a day for saw-cutting and slab removal, a day for subgrade prep and gravel, and a day for vapour barrier and the concrete pour itself. The new slab then needs a minimum 7-day cure before foot traffic and 28 days to reach full strength before flooring goes on.

Can I install heated floors with a new concrete slab in Hamilton?

Yes - in-floor hydronic or electric radiant heat installs directly into a new slab. We coordinate with the hydronic or electrical contractor to get heating elements or tubing in place before the pour, and make sure the slab thickness is adequate to embed the system properly.
