Job Stories From Greenbank, WA

Critter Issue in the Crawl Space - Greenbank, WA

When a critter enters the crawl space it can be difficult to remove them. The damp environment paired with fiberglass which makes a nice bedding material for them, and being able to escape exterior elements, can lead to a crawl space being a very welcoming space for them. The owners had replaced vent screens when they were chewed through, set rocks up in front of their exterior entryway since the wood door was chewed on, and placed traps. But the critters kept on coming back and the owners needed something new to try. John's Waterproofing proudly specializes in crawl space encapsulation. This system is built to deter critters, allowing us to control the environment and help keep your home healthy. To begin we pull out the old vapor barrier, fiberglass, and debris. We then seal all the vents shut. Since there was signs of water issues we than install a drain system and a sump pump. This will collect groundwater and direct it away from the homes foundation. We lay TerraBlock insulation over the dirt floor, and than bring in CleanSpace. This 20 Mil thick woven barrier, is difficult for critters to chew through, making it an excellent deterrent against unwanted critters. This is installed between each wooden post and its footing, is anchored along the foundation rim joists, and each and every seam is sealed shut with a special four inch wide waterproof tape. To control the spaces relative humidity we install a SaniDry dehumidifier, and install Spray Foam insulation. This completes the insulation for the space and will air seal along the foundation walls. To complete the project we install an EverLast entry cover, this is difficult for critters to chew on and will keep the exterior elements from making their way into the crawl space. The owners were thrilled with the transformation and look forward to knowing their crawl space is now built to deter critters from making their way back under the home.

Foundation Inspection in Greenbank, WA

This homeowner reached out to John's Waterproofing. They had noticed degradation in a portion of their foundation. They were looking for a professionals opinion on if the issue was something which could be addressed by repairing the impacted area, or if it was a sign of a much bigger, irreparable issue. We scheduled a design specialist to head on out to do a full inspection, after which he shared his findings with the owner and they discussed options. Ultimately the issue could be addressed and fixed with a repair plan. To begin we needed to address the damaged area. We built a form around the damaged section of the foundation wall from within the basement. We installed steel rods into the form and than poured in concrete. Once the concrete sets, we removed the form, leaving behind a sturdy and stable foundation. After completing this section of the work we installed a WaterGuard drain system around the interior perimeter. This collects and directs water to the lowest point. From there water enters a newly installed SuperSump which directs the water away from the homes foundation. A CleanSpace wall system is installed to guide water from the walls to the WaterGuard. And we complete the project with a SaniDry dehumidifier. This space is now stable and dry and the owners were so pleased to know it was a repair needed and not something much bigger.
