Footings and walls that hold for decades start with precision forming, reinforcement tied to spec, and concrete poured without voids. Laval Concrete builds new foundations and addition tie-ins from the engineer's drawings, inspected before backfill, with waterproofing and drainage included. One crew handles the full sequence. Free written estimate.
A foundation that settles unevenly or cracks early creates problems that ripple through every trade above it. Walls crack, doors jam, floors slope. The cause is invisible until the damage is visible. We work from the engineer's drawings because those drawings specify the footing depth, width, bearing soil confirmation, wall thickness, rebar placement, and concrete mix design that the site conditions demand.
Before concrete is ordered, the site is staked, the bearing soil is confirmed, and the forming is inspected. Rebar is tied to the drawing, embeds for plumbing and electrical are positioned, and the pour is consolidated without voids or cold joints. The slab cures on schedule before backfill pressure goes against the wall. For additions, the new footing ties or isolates from the existing foundation exactly as the engineer specifies, so the new and old structures move as one.
The engineer's drawings are staked on the lot, the bearing soil is exposed and confirmed against the geotechnical report, and any over-excavation is corrected before forming.
Form and reinforce footing
Footing forms are set to depth and width, rebar is tied to the drawing, and the concrete is placed and consolidated without voids.
Cure footing, form wall
The footing cures on schedule, then wall forms are erected straight and true, rebar is tied through, and embeds for utilities are positioned.
Pour wall, strip, waterproof
The wall is poured and consolidated, forms are stripped on schedule, and waterproofing and weeping tile are applied before backfill.

Waterproofing and Drainage Included in Installation
A new foundation is not finished until the exterior is sealed and water is managed. Foundation waterproofing membrane goes on the wall before backfill, and perimeter weeping tile carries groundwater away from the footing.
Skip this step and the first spring thaw can bring water into the basement. Done as part of the installation, waterproofing and drainage protect the structure for decades. The same applies to the basement floor that sits inside the foundation walls.
Drawings, footings, additions and waterproofing handoff for new foundations in Laval.
Yes. Every new foundation install is built to the structural engineer's drawings, footing sizes, wall thicknesses, rebar layouts, mix designs, and is ready for inspection at each stage before concrete is ordered or backfill goes in.
Yes. Additions usually require the new foundation to tie in or isolate from the existing footing per the engineer's design, so the new structure settles with the house rather than against it. We pour to that detail.
Below the frost line, which is typically several feet in Laval, and confirmed against the engineer's geotechnical info. The exact depth depends on the soil, the load and the local code requirements; the drawings specify it.
Yes, as part of installation. Foundation waterproofing and weeping tile go on before backfill, protecting the new structure from groundwater for the long haul.
It depends on the size, the soil, the engineering and access. We put exact numbers in a written, itemised quote after reviewing the drawings and walking the site, so the price is firm against the actual project.
Homeowner reviews
What Laval Homeowners Say About Their New Foundations
Foundation for a full custom build, footings and walls to the engineer's drawings, inspected at every stage. Project went smooth and the structure has not moved through the first winter.

★★★★★
Addition foundation tied into the existing house exactly as the engineer specified. New and old settled together, no separation at the join.

Longueuil
★★★★★
Below frost depth, properly reinforced, with the waterproofing on before backfill. They explained every step before pouring.

Repentigny
★★★★★
Embeds for plumbing and electrical placed exactly where the trades needed them. Made the rest of the build smooth and avoided drilling into a new foundation.
