Crawl Space Repair Before & After Photos

This home had a history of water issues. They had done a big structural repair a few years back to replace the damaged wooden beams and posts in the crawl space. Now that a few years had passed, they were ready for their next crawl space investment, a system built to prevent water damage from occurring. For this, they called up John's Waterproofing to get a full encapsulation! 

This crawl space was showing all of the signs of water intrusion. High levels of humidity, musty smells, sagging insulation and so much more. The homeowner reached out to John's in hopes of addressing this issue permanently and completely transforming this crawl space. After going out and thoroughly inspecting this home we came up with the best plan that will give them peace of mind.

We begin this project by removing all of the debris, fiberglass insulation and old vapor barrier. We dig a trench around the interior perimeter of the crawl space where we place a 3 inch perforated pipe into a silt sock to create a secure passage for water to drain to the lowest point, where we install the SuperSump Plus. This system pumps the water outside of the home through a discharge line. We make sure all of the vents are covered and sealed shut to prevent outside air from entering. Dirt floors can be full of moisture so we install our TerraBlock system. This is our 3/4th inch foam with a vapor barrier on both sides that will help insulate and block out moisture. Our 20 mil thick liner (CleanSpace) is then anchored into the foundation walls, placed between each footing and post as well as laid over top of the entire TerraBlock system and sealed with our heavy duty CleanSpace tape. To keep the environment stable, we install our SaniDry Sedona which will eliminate damp and musty odors by drying and filtering the air keeping a healthy relative humidity throughout the crawl space. To complete this project, we install spray foam insulation. This is sprayed onto the foundation walls, up to the rim joists and it expands, which fills every crack and void. This form of insulation guarantees a complete airtight seal. Now this crawl space is dry, stable and healthy which will give these homeowners peace of mind. 

On this project we were able to lift the building piers so we could slide our CleanSpace 20 Mil Vapor barrier in. 

This crawlspace had old concrete blocks stacked around the doorway from one portion of the crawlspace to the other. We cleaned it out and can show the work in progress look where we have the brown drainage matting connecting two rooms, with the thick TerraBlock insulation getting taped down. This job will still need Cleanspace over the top of it all to fully encapulate the area, but this is a glimpse of what we do to protect your home. 

This customer called because spiders and other insects were getting into his crawlspace. So we sent out our inspector and they recommended a CleanSpace encapsulation system. We installed a TripleSafe sump pump and SaniDry Sedona dehumidifier and air purifier will keep his crawlspace dry and humidity down. Now having a CleanSpace encapsulation he will never have to worry about water or insects again.
