Common Causes of Basement Leaks & Floods in The US

Basement leaks happen due to the immense pressure exerted against your walls when the soil around your foundation is supersaturated with water. It usually starts with a faulty or clogged drainage system being unable to properly discharge all the excess water which in turn is absorbed by the soil, expanding it and causing it to push against the foundation walls. Over time, this pressure causes water to seep into the basement through small cracks or weak spots in the walls and floor.

Installing a proper and efficient drainage system helps prevent water from accumulating around your foundation, thus eliminating the most common risk factor for basement leaks. With the addition of a powerful sump pump, you can ensure that all collected water is diverted and discharged away from your home, keeping your basement dry and safe.

French Drains
(the old-fashioned solution)

Employed as a standard groundwater drainage solution for over 100 years, French Drains – or footing drains – consist of a row of clay or corrugated pipe installed along the outer perimeter of the basement. Despite being widely used, footing drains are far from the most practical and efficient solution as they are prone to mud, debris and other particles building up over time and clogging the system, making it unable to properly discharge water. Clogged French Drains are the most common cause of basement leaks and flooding.
