Our French drain services
Mini-excavation
Installing a French drain requires excavation. Our experts start by conducting a site survey and water flow pattern analysis to determine the ideal location for your drains. Then, we use mini-excavators to dig narrow trenches along the structure’s perimeter, down to the base of the foundation.
Foundation cleaning and waterproofing
Once the foundation has been cleared by our machines, it is cleaned and waterproofed with a water-repellent membrane. Our experts also install a geotextile to prevent fine soil particles from entering the pipe and clogging it.
French drain installation
A perforated drainage pipe is placed in the trench and connected to the sump pit. While digging, our experts will have formed a slope to allow water to drain away. Once the inspection shafts have been installed, the pipe is covered with crushed stone. The geotextile is folded over the gravel, and the trench backfilled with compacted soil.
French drain replacement
We clean out the area around the foundation before installing newer, more innovative and efficient equipment. This may involve replacing the entire system or just the sections targeted by the inspection. Once the new pipes have been connected to the discharge point and the sump, the system is tested to ensure that it is working properly.
