Expert-Fondations: The Foundation Waterproofing Pros in Montreal

French Drain Specialists

Expert-Fondations specializes in foundation waterproofing and French drains. We have provided services for residential buildings, terraces and commercial buildings for over 20 years in Montreal and surrounding areas.

Waterproofing and Injection

Are your foundations cracking and starting to leak? Do you have water infiltration? Expert-Fondations uses only specialized excavators to dig out and waterproof these areas. With the combination of polymer injections into cracks and a waterproof membrane on foundation walls, you are guaranteed to get a totally sealed construction.

Many Other Services

We also provide demolition services, water and sewer entry and sump pump installation services. We take pride in bringing you full satisfaction, which is the secret to our success.
