Exterior Foundation Drainage System


When your house was first built, it was suited with a foundation drain, also known as a footing drain and a coat of black tar to waterproof the foundation walls. A foundation drain is a perforated pipe or a PVC pipe with slots on it and a bed of crushed stones on top and all around it. This type of drainage system usually does not work because it is simply not professionally designed and installed and the building inspections rigorous enough on this matter to prevent future problems. Some of the common problems with poorly installed foundation drains are the following: drain does not lead out anywhere, pipe is crushed upon backfilling of dirt, drain is clogged with dirt over time, not enough crushed stones to filter water and mud, pipe does not exist. Another common problem is related to the waterproofing coat of tar that is applied to the foundation walls. Even when well applied, this coat will last for an average of 10 years only. Over time, this coat of tar will start to loose its efficiency and eventually allow water to seep through the foundation walls contributing to your water problem.
