Frequently asked questions
What kinds of structures have you waterproofed?
Municipal or private drinking water basins, oil recovery basins, wastewater or stormwater basins, chemical tanks and fuel tanks. Both older concrete structures that leak and new tanks can be sealed.
Why does your method cost less?
It skips the filler products normally needed for every hole, honeycomb and crack in the concrete. Less preparation time means a lower cost for you.
Do you line transformer containment basins?
Yes. The membrane keeps oil away from the concrete and holds a spill until it can be cleaned up. The products resist high temperatures, and the methods are approved by Hydro-Québec and other clients. You can request a quote.
