Foundation sealing is very important in the Pacific Northwest with our occasional drenching rains. You have one chance to get this aspect right in your custom home, or it’ll cost you dearly. This is the place to install back-up systems for the back-up system, much like commercial airplanes have multiple backup systems to keep their planes in the air. We custom builders put extra effort into ensuring your home stays safe and stable on the ground.
The foundation sealing is found in situations where you have living space inside the the foundation, not crawlspace.
For the best foundation sealant, use asphaltic emulsion 3X on the dry foundation wall, glue a drainage mat to the face of the foundation wall, then install drain tile (perforated pipe) covered with a filter sock, surrounded by clean drain rock.
Next time that spring decided to form right outside the wall, you will be ready for the weather and the water.
