Installation de drain français

French drains placed around a basement foundation must be on a negative slope to a drip point. The layer of gravel covering it and its connection point constitute the drainage system foundation. This system is designed and installed to drain water infiltrating the land around a building, and at the same time prevent the accumulation of water around the foundation.

Contrary to many homeowners’ beliefs, a drainage system does not last forever. The average life span of a French drain is 30 to 40 years. Moreover, these projects also involve collateral damage, which includes landscaping around the home’s foundation. Although unpleasant, this step is virtually inevitable when we want to maintain a strong construction and good living conditions.
