Basement Waterproofing Contractor in Montreal, Quebec City, Joliette

Sump pump and SaniDry™ dehumidifier

Since Basement Systems, Inc. was started in 1987, we've been upgrading and perfecting our product line to always be the best available.

The issue of water in basements has been an ongoing problem since the first basement was built. Sub-floor structures like basements and crawl spaces are not perfect by design and are built on soil that constantly shifts and moves. Water collects around and under basements and can leak in through walls, floor slabs and in between the walls and floors.

There are contractors out there that have similar products and solutions to basement water problems. The line of Basement Systems products have been developed, produced, and updated for over 25 years in basements. We know basements!

Let our waterproofing professionals give your home a free basement assessment and fix your water problems once and for all. Being in the business as long as we have, there is not a problem we haven't seen and fixed. We serve residents in Montreal, Quebec City, Laval, Joliette, and nearby areas.

WaterGuard® drainage system

How Our Waterproofing Solutions Work

WaterGuard® is a waterproofing drainage system that rests under the floor slab. It keeps your basement dry while being clog-free from existing soil and dirt.

The openings and the extending flange collect water and carry it away from the foundation walls.

By adding a TripleSafe Sump Pump System you can ensure a permanently dry basement.

DryTrak® system DryTrak® basement water control system

Some basement floors and footings are one solid piece of concrete. These "monolithic" floors cannot be jackhammered to install some systems. For these instances we offer the DryTrak® system that sits on top of the floor and works as a basement drain.
