What is the average cost to pour a garage floor slab in Riverview NB?

Pouring a new garage floor slab in Riverview costs $3,000–$5,000 for a standard two-car garage (400–500 square feet), or $6–$10 per square foot fully installed. A single-car garage floor (200–250 sq ft) runs $1,500–$2,500.

That price includes gravel base preparation (typically 6 inches of compacted granular fill), vapour barrier, wire mesh or rebar reinforcement, a 4-inch air-entrained concrete slab, control joints, and a broom finish. If the garage is on an existing foundation and the old floor needs to be removed first, add $800–$1,500 for breaking and hauling. Adding a floor drain requires coordination with the pour and adds $300–$600 depending on the tie-in.

Riverview-specific context: Riverview sits across the Petitcodiac River from Moncton and shares similar soil conditions — a mix of marine clay and glacial till in many areas. Clay-heavy subsoil is the enemy of garage floor slabs because it retains moisture and has poor load-bearing capacity when wet. Before pouring, any organic material (topsoil, roots, wood) must be removed and replaced with compacted granular fill. A vapour barrier (6-mil polyethylene) beneath the slab is important in Riverview — without it, ground moisture wicks through the concrete and creates a perpetually damp garage floor that makes epoxy coatings peel.

Thickness recommendations: A 4-inch slab is the minimum for a garage floor. If the garage is used to store heavy equipment, a truck, or a trailer, 5 inches with proper rebar (rather than wire mesh) provides significantly better load distribution. The cost difference between 4 and 5 inches on a two-car garage is roughly one additional cubic yard of concrete — about $200–$240 — and it's worth every dollar for the added strength.

New garage slab pours in Riverview are best timed for May through September. If a heated garage is already in place, late-season pours are possible with cold weather protection.
