Sealing and Waterproofing a Nasty Crawl Space in La Rue, OH

Monday, April 24th, 2017 by Holly Richards-Purpura


It is common to never venture into crawl spaces under homes, but keeping these areas out of sight and out of mind can be detrimental to the health of a home and its residents.

Homeowners in La Rue, OH, have lived in their more than 100-year-old home for many years. They, too, have refrained from checking out the crawl space. Recently, however, these homeowners began to question the health and safety of this area. Considering the homeowners suffer from allergies, they wondered if anything in the crawl space was affecting the condition of the rest of the home.

While they were taking in the sights and information at a local home and garden show, the homeowners started talking about their concerns with some of Ohio Basement Authority’s staff at our company booth. The owners were eager to learn more about how we could help them transform their crawl space, and they set up an appointment to meet with one of our inspectors.

One of our inspectors then completed a thorough evaluation of the crawl space. He found puddles of water that most likely seeped into the crawl space from open vents, failing insulation, and a generally nasty environment under the house. He then presented the homeowners with several options we could use to improve the health of their home.


Alarmed by the condition of the crawl space, the homeowners were equally eager for one of our expert crews to complete these repairs. One of our crews then waterproofed and encapsulated the crawl space.

We installed the CrawlDrain drainage system throughout the crawl space perimeter. These pipes will catch any seeping water in the crawl space and direct it to the SafeDri Pro sump pump. The SafeDri Pro then pumps this water out of the crawl space and away from the home’s foundation through a lengthy discharge line that was installed on the property.

Thick drainage matting was placed on the crawl space floor to help direct water to the CrawlDrain system and enhance the durability of the encapsulation system. The crawl space was then encapsulated in CrawlSeal liner. The thick CrawlSeal liner, which is similar to swimming pool liner, fully seals the crawl space environment from the earth. It also serves as a moisture and vapor barrier that helps insulate the crawl space and improve its appearance, as well. The crawl space was further sealed from outside air, precipitation, and pests by vent covers that were placed on the home’s exterior.

The homeowners were pleased they finally addressed their crawl space so their home will be a healthier living environment for many years to come.
