Waterproofing and De-watering

Waterproofing is the process of preventing water from entering a basement or crawlspace, and must be done from the exterior of the structure. (Sealing a wall on the inside traps water within the wall and actually speeds up the deterioration of the wall.) Waterproofing must be accompanied by good drainage or it is doomed to failure.

De-Watering does not block the path of water as with waterproofing. De-Watering, instead, contains and then gets rid of water.

You rarely need to have both interior de-watering and exterior waterproofing done for the same walls. Sometimes, however, a combination of both techniques is best—waterproofing on some wall sections and de-watering on others.

When the original foundation protection against water intrusion has failed, Interior De-Watering is often the method of choice as it is usually a more cost effective and less disruptive process. We refer to these as ‘retrofit’ installations

Lindsley Waterproofing offers both exterior waterproofing and interior drainage systems.
