French Drain

This is a perimeter drain, or a French drain, found quit often in Ottawa and it is the best way to stop a basement from flooding. This type of drain is a trench filled with rock or gravel that guides water running on the surface away from the area it surrounds. In some instances, a perforated pipe is used in place of the gravel or rock. The drain can also have a combination of gravel with a perforated pipe underneath to redirect any water that filters or seeps down through the gravel.

The main feature of a French drain is that it can be made from a gravel substitute, which is lightweight, wrapped around the perforated pipe and covered with a filter fabric. Here in Ottawa this type of drain is found primarily utilized in preventing surface water from contacting a foundation avoiding any damage. Moreover, they are also used to accompany a retaining wall. When this type of drain is utilized in this manner, they help reduce surface water pressure.


They underpinned our basement in summer 2017. They finished ahead of schedule and did a great job!
