Crawl Space with no Protection in Depoe Bay, OR

This crawl space was bare. It had no barrier or protection against water intrusion. These homeowners noticed a damp odor in their home, especially during the rainy season. Wanting to find a permanent solution, they reached out to John's and scheduled their free visit. We sent out one of our system design specialists to perform a thorough inspection. After he was done, he went to meet with the homeowners to work with them in creating a dry, healthy and stable home that will give them peace of mind. They discussed the plan, then they moved forward with the estimate and scheduled their project.  Since this crawl space did not have a vapor barrier, or fiberglass insulation- we begin by digging a trench around the interior perimeter of the crawl space and in that trench we install a 3 inch perforated pipe into a silt sock. This creates a secure passage for water to drain to the lowest point. At this low point, we install our TripleSafe Sump, which will collect all of the water that enters and pump it outside of the home through a discharge line. All the vents in the crawl space are then covered and sealed shut to prevent outside air from entering. Our TerraBlock system is placed onto the dirt floor, not only does it block moisture from making its way up through the dirt floor but it acts as an insulated barrier between the home and the earth. Next, we install our CleanSpace system on top of the TerraBlock. This 20 mil thick liner is tear resistant and brightens up the crawl space with its white finish. This is also installed between the footing and the wooden posts as well as anchored into the foundation walls, up to the rim joists. everything is then sealed at with our heavy duty CleanSpace tape. To keep the environment controlled, we install our SaniDry Sedona. This dehumidifier will effectively eliminate damp and musty odors by drying and filtering the air. It will also raise indoor air quality because it will keep the home at a healthy relative humidity. Finally, to finish this encapsulation we spray our foam insulation onto the foundation walls to fill every crack and void to guarantee an airtight seal.
