Interior French Drain

An interior French drain should be used if you cannot keep water from seeping into your basement, since it can involve some extensive work within your living space. Generally, a channel is cut around the perimeter of the basement floor. Perforated pipe is laid all the way around. The perforated pipe and stone field then directs the water to a collection tank sunk into the floor and a sump pump carries it out to the yard or a storm drain. The channel is patched with a thin layer of concrete, except for a small gap at the edge to catch any water that comes down the wall. Again, discuss sump pump capabilities with a waterproofing professional, such as Vulcan Basement Waterproofing.

Cases involving hydrostatic pressure (water pressure from things such as underground springs, rivers, ground water, etc.) and a fluctuating high water table (a build-up of ground water that lies close to the surface of the earth). A basement affected by one or more of these conditions pose a special problem. Signs of their presence is indicated by water that seeps in at the cove (where the wall meets the floor) or up through the slab floor. The solution to these problems lie (1) in relieving the water pressure under the floor and around the foundation perimeter and (2) in diverting the water to a point where it can be pumped out or otherwise removed from the basement.

To successfully arrive at this solution, one method advocated by the Vulcan Basement Waterproofing people employs a pressure relief system.
