Basement Excavation (Digging out) & Underpinning the Foundation Walls

We offer two methods to dig out your basement. The first is manual excavation, which involves our skilled personnel working by hand. Alternatively, we can use a mini excavator by removing an outside wall to speed up the process.

Underpinning involves digging out the basement in sections and adding a new foundation footing and wall beneath your existing foundation. We use steel rods (rebar) to “sister” the old and new walls, ensuring structural stability and adding height to your basement.

I completed my french drains with Solage Solide in 2019 and it was an excellent experience. The work was top notch and I haven't had any problems since! Having Matthew simplify and explain the work that needed to be done gave me peace of mind.

Recently had Jordan and Brad come fix a crack on my foundation and could not be happier with the service. They were polite, professional and did a great job fixing the crack. I am very happy with Solage Solide and would easily recommend them to others.
