Olympic Restoration Systems Case Studies: Moisture Control in the Crawl Space

Thursday, December 14th, 2017 by Heather Harris


A homeowner, frustrated with high heating and cooling bills, decided to contact our team to see if the cause might be the crawl space


Our team assessed the situation and found high humidity readings in the crawl space and condensation on the subfloor. The crawl space also wasn't insulated. A decision was made to encapsulate the crawl space, separating the home from the dirt floor, excess moisture and air flow rising into the home.

First, our team regraded the crawl space to direct water seepage to a sump pump system. Next, we installed an EZ flow pipe around the perimeter of the crawl space to capture incoming water and direct it to the sump pump. Afterwards, we installed a SmartSump pump system with liner, cast iron pump, CleanPump Stand, airtight lid with an airtight floor drain and WaterWatch alarm system. CleanSpace drainage matting and a CleanSpace vapor barrier were placed along the ground, walls and piers. A SaniDry dehumidifier was also used to assure the humidity in the crawl space was controlled and two wireless sensors were fastened to send temperature and humidity readings to a small panel inside the house.
