Excavating and Concrete Work in Smithville and the Niagara Region
Forming and pouring concrete is where Theriault Forming Construction Ltd. started in the 1980s, and it is still the backbone of what we do. We handle the excavation, the forming and the pour ourselves, for homeowners and small builders across Hamilton and Niagara.
Excavating
Excavation for new foundations and additions, trenching for drainage and services, and site preparation. We bring our own equipment and operators, so the excavation and the concrete work that follows are planned together and done by the same crew.

Basement and garage floors
Patios, walkways and sidewalks
