Ready for a price? Send your drawings and we’ll reply the same day.

Why our own forms matter

Looking for a contractor for foundation work who shows up on the day? Most foundation jobs slip because the forms or the crew aren’t ready. As concrete foundation contractors with our own forming system and our own crews, we set the pour date and we keep it.

We also do the framing. The hand-off from foundation to framing doesn’t wait on a second company.

How we work

Every step, every inspection

Two kinds of job, one standard. Every stage is checked against the drawings, and every inspection is booked before the next pour.

Concrete contractors for home builders

Need a foundation subcontractor in Toronto and the GTA? Send us your drawings and the dates you need. Footings, walls, slabs and framing priced as one package, on one crew schedule, with WSIB clearance and insurance certificates on request.

Questions homeowners ask

Yes. The City requires a building permit to underpin or lower a basement, and to add a below-grade entrance. We don’t dig until it is issued.

Often, yes. The City requires a professional engineer to design and review the work when the new footing goes below your neighbour’s footing, when the unsupported height is over 1.2 metres, or when the soil is clay or silt. In every case the City wants engineer reports at the start and end of the work.

Yes. We pour the footings, walls and slab, then frame the house or addition. One company, one schedule.

A structural concrete slab that spans over a room below, usually a cold cellar or basement space under the garage. It is formed, shored and reinforced to the engineer’s design, unlike a slab on grade that sits on compacted ground.

Yes. A walkout means cutting the foundation, new footings and walls around the opening, and concrete stairs or a landing. In Toronto it falls under the underpinning permit, and we build it as one job.

Yes. We frame laneway houses, garden suites and second storey additions, and we can pour their footings and foundation walls too.

Our work is new construction and underpinning, not repairs. If your foundation needs to be lowered or rebuilt, that is where we come in.

Usually within 1 to 2 weeks of a signed quote. Call us and we’ll give you a real date.
