Several factors can cause drainage failure. Among these there is the absence or obsolescence of the French drain, whose lifespan is about 30 years. The French drain may also collapse or get clogged with soil, roots, or get contaminated by iron ochre. It may also have been poorly installed. Its effectiveness is reduced when installed near the ground surface or too deep.
Moisture caused by an accumulation of water around the foundation causes seepage on the inside perimeter of the slab and the wall bottoms, traces of inflorescence, and even, on occasion, water seepage, especially during thawing or heavy rain.
To function effectively, a French drain must be installed by professionals, while observing good practices. This drain must capture the water that streams along the foundation and evacuate it by gravity or pumping. By entrusting your French drain to the F. Gélinas experts, you'll have peace of mind. Installation will be flawless and at the best price on the market.
