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.

A residential concrete contractor builds the structural concrete of a house: footings, foundation walls, and garage and basement slabs. GSS does that work across Toronto and the GTA.

Toronto and the GTA: North York, Etobicoke, Scarborough, Mississauga, Brampton, Vaughan, Markham, Richmond Hill, Oakville, Burlington, Hamilton, Pickering, Ajax, Whitby, Oshawa, Newmarket, Aurora, Barrie and Orillia.

Usually, yes. Footings, foundation walls and suspended slabs are built to an engineer’s stamped drawings, and the City reviews them with the building permit. We build to those drawings and the Ontario Building Code.

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. We fabricate custom rebar to the engineer’s drawings and supply the concrete, then install both with our own crews. Buying in bulk keeps material prices down, and you deal with one source for the whole foundation.

Yes, in parking garages and commercial and industrial buildings. Along with new footings, walls and slabs, our crews repair columns, suspended slabs and ramps, garage foundation walls, and cracks that leak. Most repair work follows an engineer’s repair spec, and we can also look at the problem on site. See concrete repair and garage restoration.

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