About Us · Solex Excavation
One single discipline since 2007: the installation and replacement of French drains. No diversification, no amateurism. Just one trade, performed with rigour, project after project.
Our Story
A journey defined by a single choice: refusing to diversify to excel in one single discipline.
2007
Solex Excavation is born in Sainte-Catherine, on Montreal's South Shore. A single goal: to become the go-to partner for residential and commercial French drains.
We decided against diversification. The team focuses exclusively on installing and replacing French drains-no general plumbing, no landscaping.
Registered with the Régie du bâtiment du Québec. All our worksites comply with the Building Code, without exception.
1970
Hundreds of clients served on the South Shore and in Greater Montreal. A permanent, internally trained team that stands by the same proven method.
What defines us
A proven method, honed project after project. Each step, from diagnosis and excavation to installation and backfilling, is executed according to the same protocol by the same team.
Since 2007, we have focused our know-how on foundation health. Excavating, diagnosing, and protecting a home's perimeter every day develops a deep understanding of soil, water, and building structures-an expertise that a general contractor cannot match.
All our work complies with the requirements of the Régie du bâtiment du Québec. A written warranty is provided at the end of each project, in addition to manufacturer warranties.

The Founder
It was Patrick Fournier's initial commitment that laid the groundwork for Solex Excavation in 2007. A clear decision from the start: to become the preferred partner for the health of residential foundations, from French drains to crack repairs.
This complete specialization has allowed the company to earn the trust of hundreds of clients on the South Shore and in Greater Montreal, thanks to undeniable professionalism and proven drainage solutions.
Today, the permanent team carries on the same method, job after job, without subcontracting and without guesswork.
