Waterproofing your basement prevents outside water from coming in but what if a pipe bursts or the water heater leaks inside the home.

Job Stories From Cascade Locks, OR
Water Pooling in Crawlspace and Basement - Cascade Locks, OR

This home was originally build with a basement, made of poured concrete. The homeowners had a addition added on, which then created a small section of crawlspace as well. The home dealt with water entering both spaces during the rainy season, and it seemed to progressively get worse as the years passed. Due to the prolonged water damage, the home soon showed evidence of foundation issues, one of the bedrooms experienced a large crack along the floorboards where the lower beams were rotting away. To save their home before more damage occurred, John's Waterproofing was called in to tackle this crawlspace and basement waterproofing job. 

We began by removing any debris that was found under the home. To combat the drooping foundation, we started work in the crawlspace. Three of the support beams were experiencing rot, and the fiberglass insulation was a soggy mess. Once it was cleared out we laid down TerraBlock insulation. We isolated each pier so it couldn't receive more water damage and added in five SmartJacks to provide additional structural support where needed. We then covered the space in Cleanspace, a 20 Mil woven vapor barrier that is sealed against the walls, to fully encase the basement. to add in insulation along the poured walls of the concrete we did spray foam. Finally we added new vent covers and a new Well Duct so that it would be a contained space with nothing getting in. 

Next the basement was tackled. We dug a trench along the interior walls and installed a WaterGuard pipe system to take the water to the TripleSafe Sump Pump we added in. This would pull the water out of the space and get it a safe distance away from the home. Next we added BrightWall paneling to ensure any water getting through the concrete walls would safely get to the sump pump as well. 

This combination crawlspace and basement is now ready for the rain, and the homeowners can rest assured that their home is protected against water damage. 

Wet Crawl Space in Cascade Locks, Oregon

A homeowner in Cascade Locks, OR called with concerns about her wet crawl space and the musty odor it seemed to be causing in her home. Our crews went out to fix the problems. After removing all of the debris from the crawl space, our team installed CleanSpace encapsulation system on the floors and walls of the crawl space. This thick liner prevents any moisture or water vapor from coming into the crawl space through the walls or floor. CleanSpace means that there won't be any new mold growth. It also helps to keep out pests. Our crew also installed an insulated vent cover over the open vent of the crawl space. This prevents any cold, hot or humid air from coming into the crawl space from outside. Not only will this help with the musty odors but it also lowers energy costs throughout the home. A SaniDry Sedona dehumidifier was also installed in the crawl space. This dehumidifier eliminates damp and musty odors in the crawl space by drying and filtering the air. Now this homeowner can rest easy knowing that her crawl space in dry and the air in her home is healthier for years to come.
