This homeowner contacted us when they noticed that their crawl space had water in it. When heavy rains hit, puddles of water would be found over top of their 6 Mil vapor barrier. The owners of the home were concerned about the negative effects this would have on their home so they contacted John's Waterproofing to discuss options for their home. After a full inspection we sat with the owner and worked on a repair plan, ultimately moving forward with a full encapsulation. This system will seal the crawl space off from the exterior elements, allowing the space to become more energy efficient and remain dry and healthy over the years.

Job Stories From Marysville, WA
Keeping Crawl Spaces Dry in Marysville, WA

This homeowner was experiencing water coming into their crawl space and didn't know where to begin to fix this issue. They decided it was best for a professional to come in and called John's Waterproofing. Upon inspection, it was discovered that water had been seeping into the crawl space for a long time. We suggested that a full encapsulation would be able to stop the water from seeping through and promote a healthy living space for the homeowner.

The first necessary step in an encapsulation is removing the falling fiberglass insulation and damaged vapor barrier. Then, we can install a drainage system using a perforated pipe that safely collects water and gives it a passageway to the TripleSafe sump pump. This sump pump takes all that water and sends it safely away from the homes foundation. It is a three-pump system that is installed at the lowest point in the crawl space. Next, we install TerraBlock insulation. This is a durable and thick foam designed to help control the environment by sealing the home off from the earth. It helps promote energy efficiency by helping to keep the outside air from getting into the crawl space so your heating/cooling systems don't have to work as hard to keep up with temperature changes. Then, we install the CleanSpace vapor barrier. This goes over top the TerraBlock, up the foundation walls, and between the concrete footing and wooden posts. It's primary function is to keep water out and is sealed in place with thick waterproof tape. A SaniDry dehumidifier gets installed to help filter the air and pull out moisture particles that can get into the living space. Finally, Spray Foam is applied along the foundation walls as a final insulation and air sealant. Now, the crawl space is protected from water seeping through and the homeowner can enjoy the benefits of a dry crawl space.
