Larry Janesky of Basement Systems reviews the work being done to cut a drainage trench in the concrete around the perimeter of the basement floor. Water will be channeled through the trench to a sump, where it can be pumped out of the home. The sump hole was dug at the lowest spot in the basement as determined by laser level. CleanSpace is being installed over the walls as a vapor barrier to drain water from the walls to the drainage system. It is possible to install CleanSpace in crawlspaces as well as in basements to prevent water buildup in underground walls and eliminate rot and mildew. Janesky recommends taking these two steps in securing the drainage of a home and to secure against all outside air leaks. The final step is to dehumidify the crawlspace. Janesky points out a corner of the basement where the Thermal Dry Wall System has been installed. This product goes behind finished walls and drains water like CleanSpace but also reflects heat generated in the basement back into the basement. Janesky then shows a portion of the floor where the Water Guard Drainage System has been installed in the drainage trench and secured with cement.
