Waterproofing a Flooding Crawl Space in Kenton, OH

Tuesday, May 30th, 2017 by Holly Richards-Purpura

Challenge

Homeowners in Kenton, OH, moved into their house not long after it was built almost 25 years ago. When they did so, they never imagined they’d have to deal with a flooding problem.

They rarely venture into the crawl space, but after recently peeking into this area underneath the house, they noticed the floor was saturated with water that leaked inside. It was obvious the existing sump pump system was failing to properly work and pump the water out of the crawl space. Along with standing water, the insulation in the crawl space also was failing.

The homeowners wondered if these conditions could negatively impact the health of their home, and they wanted to address these problems for good. They were motivated to take action after seeing Ohio Basement Authority represented at a local home and garden show. They spoke to some of our staff, and they were eager to set up an appointment to meet with one of our inspectors. Brendan Kent then completed a thorough evaluation of the nasty crawl space and recommended several permanent solutions to remedy the unhealthy conditions.

Solution

Foreman Jose de Jesus Tellez Ortiz led his crew in transforming the crawl space.

After ridding the crawl space of water, debris and other nuisances, we waterproofed the area by installing the CrawlDrain drainage system and a SafeDri Pro sump pump. If any water seeps into the crawl space, it will be intercepted by the CrawlDrain System. The water is then directed to the sump pump so it can be pumped out of the crawl space and away from the home’s foundation.

We then encapsulated the crawl space in CrawlSeal liner. Similar to swimming pool liner, CrawlSeal is thick and durable, and it completely seals the crawl space from the earth. It also serves as a moisture and vapor barrier, and it helps insulate the crawl space. Its durability is enhanced by drainage matting that was placed on the floor underneath it.

We further insulated the crawl space by placing ExTremeBloc insulation panels on the walls and applying spray foam insulation to the band joists. To further seal the crawl space from outside air, pests and precipitation, we covered the crawl space vents with durable vent covers. The access well also was added to the home’s exterior as a secure access point.

The homeowners are happy to have a dry and healthy crawl space, which enhances the health of the rest of their home.
