Cleaning Up the Crawl Space with TerraBlock - Salem, OR

After experiencing years of water intrusion in the crawl space, this homeowner started noticing a musky odor in their home. They decided to inspect the crawl space and found that the fiberglass insulation was completely destroyed from moisture damage. It was falling from the sub-floor and beginning to mold and mildew. They decided to call John's Waterproofing about a solution for their insulation. We informed the homeowners that when we do full encapsulations, TerraBlock gets installed. This is a 3/4 inch thick insulation foam that goes along the base of the space. It is designed to seal the earth off from the home and help regulate the environment. By keeping the temperature in the crawl space the same, this helps with energy efficiency because the heating/cooling systems don't have to work as hard to keep up with the changing outdoor climate. TerraBlock gets cut to perfectly fit each individual crawl space, therefore it can avoid having gaps or holes for water to intrude through. The TerraBlock is then covered over with CleanSpace, a 20 Mil woven vapor barrier that anchors along the walls by the rim joist. Overall, this homeowner was very pleased with their new insulation and cleaning up the crawl space to rid the smell in their home.

Addressing Musty Smells in the Crawl Space - Salem, OR

When a home has damp and musty smells, it is likely due to high levels of humidity caused by water entering the crawl space and becoming stagnant with no proper drainage, or adequate protection against moisture. The air that is coming in through the vents in the crawl space moves up into the living area, affecting the air that is circulating throughout the entire home. This is called the stack effect. Often times, strong odors like these are an indicator that the issue escalated into more than just water intrusion. These homeowners noticed a strong musty smell coming from their crawl space and knew it was time to call us and set up their free visit. We sent out one of our system design specialist who performed a thorough inspection of the entire crawl space. He then met with the homeowner to go over the findings and the best options to properly address this problem. After going over the estimate they decided to move forward with a full encapsulation and we began the project.

First, we remove all of the debris. This includes the old vapor barrier and fiberglass insulation. Then, we dig a trench around the interior perimeter of the crawl space and in this trench we place a 3 inch perforated pipe into a silt sock which will help secure a proper passage for water to drain to the lowest point. At this low point, we install our SuperSump Plus system that collects all of the water that enters and will pump it outside and away from the home through a discharge line. We make sure to cover and seal all of the vents to prevent outside air from entering. Next, we install TerraBlock, made of 3/4th inch foam insulation which is designed to be installed onto dirt floors and includes a white vapor barrier. Over top of the TerraBlock system we then install CleanSpace. This 20 mil thick liner is also installed between the footing and posts and this whole system is then sealed with our heavy duty and waterproof tape. We anchor this liner into the foundation walls, up to the rim joists as well. To keep a controlled environment, we then install our SaniDry Sedona dehumidifier. This system will effectively eliminate damp and musty odors by drying and filtering the air. It will keep the home at a healthy relative humidity, which helps improve overall indoor air quality. Lastly, we finish this project by anchoring our SilverGlo wall insulation into the foundation walls. With this crawl space now fully encapsulated, these homeowners no longer have to worry about any musty smells or water entering their home.

The Dream Crawl Space - Salem, OR

Is your crawl space filthy, wet, and stinky? If so, you're not alone, and John's is here to help with professional encapsulation! Our expert crews have specialized in waterproofing for over 50 years, and we take great pride in transforming forgotten, nasty crawl spaces, into pristine, dry, and healthy areas. Encapsulated crawl spaces are sealed entirely, to prevent water, rodents, and debris from entering, while maintaining clean, healthy air. Our crews carefully install the highest quality, professional-grade waterproofing and insulating components available, to ensure a lasting, effective encapsulation to protect your home from water damage, and to preserve the health of your family. Crawl spaces that are not waterproofed, leave homes at terrible risk of structural damage, while also negatively impacting the health of families, as 40% of interior air, comes from below. This means that whatever is beneath your home, is also inside of it. Wet crawl spaces are breeding grounds for mold, bacteria, and rodents - all of which are toxic. With an encapsulated Crawl space, toxic air becomes a thing of the past. A heavy-duty dehumidifier is installed to clean and filter the air, removing all moisture, allergens, and toxins, while maintaining a safe relative humidity, and preventing mold growth. Thanks to the 100% air-tight seal of an encapsulated crawl space, as well as the operation of the dehumidifier, and several other waterproofing components, the air both beneath of, and inside of the home remains healthier. In order to protect your home and family from the devastating effects of water damage.

Installing a Sump Pump to Stop Stagnant Water in Saint Benedict, OR

Water was coming into the crawl space, and standing in the low spot. Stagnant water can led to issues, and to be proactive, John's Waterproofing was called in. To make improve the space we would install a pipe, pump, plastic. A full interior drain system was installed. This will collect the groundwater, channeling it to the lowest point in the crawl space. From here the water goes into a TripleSafe sump pump and is directed away from the homes foundation. We than lay down a new 6 Mil vapor barrier, which we overlap the edges on and run up the walls and anchor. Now this space is protected against stagnant water.
