    Encapsulating and Waterproofing a Leaking Basement and Crawl Space in Millfield, OH

    During the year that they have lived in their house, homeowners in Millfield, OH, noticed issues in their basement and crawl space areas. These included moisture and improper insulation, which became more evident during cold winter months.

    The homeowners wanted to ensure the health and safety of the 150-year-old house. During their research for repair options, the homeowners learned more about Ohio Basement Authority online and they were eager to contact us for help with transforming their basement and crawl space areas.

    After meeting with Inspector John Becker Sr., the homeowners were excited for the crew to install several reliable basement waterproofing and crawl space repair products. Because of the older home’s dirt crawl space and basement flooring, the CrawlDrain drainage system was installed to catch any seeping water. This water is then directed to the SafeDri ProX sump pump in the basement that will pump the water out of the home and away from the foundation.

    Both the crawl space and basement were encapsulated in CrawlSeal liner. This thick, durable liner completely isolates these environments from the earth. CrawlSeal also acts as a moisture and vapor barrier, and it helps insulate the basement and crawl space. Additional insulation measures included applying spray foam insulation to the band joists and placing foam insulation panels on the crawl space and basement floors before the encapsulation process.

    The homeowners are excited to have a basement and crawl space that will now be safer, drier, and healthier because of these reliable repair solutions.

    An Unhealthy Crawl Space in Nelsonville, OH, is Encapsulated and Waterproofed

    After one year of owning their vacation home, homeowners in Nelsonville, OH, began to notice various issues such as cold floors and water collecting in the crawl space. These issues can lead to an uncomfortable and unhealthy atmosphere within the home.

    The owners wanted to be sure this home away from home would be a safe and healthy living environment, so they contacted Ohio Basement Authority after learning more about our crawl space repair services online.

    We completely transformed this unhealthy area underneath the home by installing several of our reliable crawl space repair products.

    The crawl space was encapsulated in CrawlSeal liner, which acts as an insulating water and moisture barrier. This liner is also compatible with the SafeDri sump pump that was installed to pump any seeping water out of and away from the crawl space. Spray foam insulation also was added to the rim joists for extra insulation.

    The sump pump discharge line was tied into a new downspout conductor line. Exterior vent covers were also placed over the vents to prevent pests, outside air, and precipitation from entering the crawl space.

    The homeowners were excited these various permanent solutions were installed so their vacation home will be a healthy place to visit for many years to come.

    Homeowners in Logan, OH, have noticed their unhealthy crawl space environment affecting the rest of the home. The existing crawl space insulation and sump pump were both failing, support beams were rotting, and floors were very cold during the winter.

New downspout lines were installed outside the home, and a FreezeGuard was attached to the exterior sump pump discharge line. Vent covers were also added to the home's exterior.

    IntelliJacks were installed to stabilize the above floors, and support beams were added to existing beams.

Features of the CrawlSeal® Liner:

  • Heavy 20-mil-thick liner – Similar to a swimming pool liner
  • Manufactured in 7 layers – Combination of high-density polyethylene for puncture resistance, low-density polyethylene for flexibility, and polyester cord for reinforcement for brute tear resistance
  • White finish brightens the crawl space and makes it easy to see that the crawl space is free of mold, insects, and dirt
  • Antimicrobial additive prevents mold from growing on the liner

How a Crawl Space Moisture Barrier Works

A vapor barrier does exactly what its name says: it provides a barrier against water vapor. When warm air comes in contact with a cool surface, condensation forms. When this happens inside the crawl space, the moisture can lead to mold growth, cause wood beams to rot, and attract pests.

A vapor barrier slows or prevents ground water seepage from evaporating into the crawl space air. For a crawl space to stay dry, it’s also important to make sure there’s proper drainage and keep gutters and downspouts clear of debris.

Our Crawl Space Vapor Barrier Installation Process

  1. Wood and organic materials are removed.
  2. Rocks are removed and uneven surfaces are leveled (depending on condition).
  3. The CrawlSeal® liner is carefully fitted and installed on the crawl space floor and walls.
  4. Drilled-in fasteners and spikes are installed to permanently hold the liner in place.
  5. Edges, seams, and pipe penetrations are sealed.
