Crawl Space with Water Intrusion- Bellingham, WA

These homeowner were smelling a musty odor and suspected their crawl space was the main culprit. They called John's waterproofing to schedule their free estimate and inspection. Once our system design specialist was done, he met with the homeowner to go over what he found and than designed the best option to create a healthy and dry crawl space. After going over the estimate they went ahead and scheduled their project.  We start removing all of the debris, including any fiberglass insulation and vapor barrier. Next, we dig a trench around the interior perimeter of the crawl space to then install a 3 inch perforated pipe into a silt sock which will secure a passage for the water to drain to the lowest point. At this low point we install our SuperSump plus which will take all of the collected water and pump it outside and away from the homes foundation via discharge line. TerraBlock is installed on the floor of the crawl space which creates an insulated barrier between the home and the earth. On top of the TerraBlock, we install our 20 mil thick liner called CleanSpace. This is anchored into the foundation walls up to the rim joists and sealed at the footing of the wooden posts with our waterproof tape. We also cover all of the vents to prevent outside air from entering. This blocks pests and rodents from entering. To keep a controlled environment, we then install our SaniDry Sedona. This is our effective dehumidifier that will keep the home at a healthy relative humidity all while eliminating musty and damp odors by drying and filtering the air. To finish this project, we install our foam insulation. Unlike traditional fiberglass, this foam is sprayed all along the foundation walls in layers, expanding and filling every crack and void to guarantee an airtight seal.
