Transforming a Flooded Crawl Space- Vancouver WA

This crawl space was completely flooded and was creating multiple issues for this home. Wanting a permanent solution, this homeowner reached out to John's Waterproofing to get the job done. We sent out one of our system design specialist to perform a free inspection and estimate. After the inspection, our design specialist met with the homeowner to discuss solutions for this space and they agreed a full encapsulation would be the best option for this nasty, wet space. To begin, we removed all the debris and damaged fiberglass insulation. Since this crawl space had a lot of standing water, we had to dry out the space. All the water in the space caused a lot of moisture and humidity, which led to some mold growth, so we spot treated the mold stains with our highly effective cleaner, Mold-X2. We then dig a trench around the interior perimeter of the crawl space to lay down a perforated pipe into a silt sock. This will secure a safe passage for the water to drain to the SuperSump Plus pump at the lowest point. We install a discharge line outside to drain the water away from the foundation. Our LawnScape outlet is connected to this line. It is a grated drain that allows water to pass through but keeps debris out of the discharge line. We then install a RainDrain, which will collect water before it gets to the home and will drain it away. Next, we install our TerraBlock system. This goes directly on the dirt floor of the crawl space creating an insulated barrier between the home and the earth. With this barrier, it will keep moisture from making its way up through the crawl space flooring. On top of the TerraBlock, we install our CleanSpace system. This goes all along the foundation walls, up to the rim joists and is sealed at the footing of the wooden posts with our waterproof tape. All the vents in this crawl space are then sealed. This will prevent outside air from entering the space. Then, we install our SaniDry Sedona to control the environment. This effective dehumidifier will eliminate damp, musty odors by drying and filtering the air, and will keep the home at a healthy relative humidity. To finish this project, we install our foam insulation. This is sprayed all along the foundation walls, up to the rim joists ensuring an airtight seal in this space.
