Properly Waterproofing and Sealing a Nasty Crawl Space in Athens, OH, For a Healthier Home

Tuesday, May 1st, 2018 by Holly Richards-Purpura


While the owners of a home in Athens, OH have lived in their house for 30 years, they rarely venture into the crawl space. A recent peek inside revealed some significant issues, however. Even though this area under the house had a sump pump system, there still was standing water. The insulation and plastic floor liner also was failing.

The homeowners were motivated to address these problems once and for all. During their research for potential repairs, the owners came across information about Ohio Basement Authority on online resources like Home Advisor. They were eager to contact us to learn more about how we could help them.

The owners met with one of our inspectors, Drew Black. Drew visited and completed a thorough evaluation of the crawl space. He also noted the crawl space had open vents, which easily allow outside air, water and pest into the crawl space to add to the existing problems. Drew discussed his findings with the homeowners, as well as their goals for a repair project. He then presented the owners with some of our reliable crawl space repair solutions.


One of our crews then transformed the crawl space by waterproofing and encapsulating the area.

First, the CrawlDrain drainage system was placed in the crawl space floor. CrawlDrain is designed to accept water from the walls and floor and then direct it to the SafeDri sump pump to be pumped out of the crawl space. Drainage matting also is placed on the floor to help direct any water to the CrawlDrain system, as well as to enhance the durability of the encapsulation material.

The crawl space was then encapsulated in CrawlSeal. This thick and durable liner, similar to swimming pool liner, completely seals the crawl space and isolates it from the earth. CrawlSeal serves as a moisture and vapor barrier, and it helps insulate the crawl space.

The homeowners now have peace of mind knowing these trustworthy solutions have helped them create a safer and healthier living environment.
