Drainage is an efficient way to control rain water penetration through foundation walls and to prevent moisture and condensation problems in basements.

Curtain drains

You may dig a trench alongside the house - about 1-foot deep - and fill it with gravel and a perforated PVC pipe. The goal is to drive the surface water away.

Use dry wells to receive run-off.

A Dry-Well is an underground structure that can receive the flow of water from rain, snow melt or other sources, dissipating it into the ground... This structure should be placed at least 12 feet from the house, and can involve a tank or a deep hole filled with gravel covered with landscape fabrics.

To solve moisture and water problems in basements, before waterproofing any walls or applying any insulation, you should install drain footings around the house and study the gutters and downspouts.

Creating An Underground Drainage System

An underground drainage system is usually a combination of a gravel drainage layer with a drain pipe or perforated PVC pipe.  Drain pipe is usually placed on top of the footing.  Cleaned gravel, crushed gravel, or crushed rock is placed around the drain pipe, and close to the walls.  Gravel is very important and will avoid many problems.
