Basement excavation with underpinning foundation

Need space?

Excavating your basement would allow you to get a comfortable living space. Do not hesitate to contact Bisson Expert, the foundation expert.

The solution: underpinning excavation

Basement excavation as well as underpinning the foundation require a structural engineer to get the work done legally and in a safe manner.

Bisson Expert has its own engineering department and carries out a great number of underpinning work annually.

"We have to consider the state of the existing foundation, the type of soil: sandy, clayey, or rocky and the living space required,” says Yvonick Houde, structural engineer at Bisson Expert.

The structural support, excavation, pouring of concrete and waterproofing of the new foundation are done with great care.

We do everything to bring your project to completion in a worry-free manner and with complete peace of mind.
