A few years back, we got called to a site off Boulevard Saint-Joseph where a new subdivision had standing water on the road base after every rain. The contractor had laid the gravel but skipped the drainage layer. Within a month, the subgrade turned to mush and the whole section had to be dug out. That job taught us that getting the geotechnical road drainage right from the start saves everyone time and money. Before we recommend any system, we run field tests to measure permeability and water table depth. In Drummondville, where spring thaws can saturate the ground for weeks, a standard roadside ditch often isn't enough. We combine surface and subsurface drainage solutions to keep the road structure dry and stable year-round.
In clay soils around Drummondville, surface drainage alone never works. You need a subsurface system that intercepts water before it reaches the subgrade.
