What are the signs of a leaky crawl space and why is crawl space waterproofing important

Have you discovered signs of water in your house’s crawl space? Did you know that there are waterproofing systems specifically designed for crawl spaces? If your crawl space has signs of flooding then you should act fast. Water and heavy moisture in the crawl space can cause many problems for homeowners. From mold and mildew, to structural damage and even “spongy” floors above the crawl space. The damage will continue to get worst and cost you significantly more to repair.

Causes of a leaky crawl space

Sewer backups

Heavy rains can cause sewer systems to be back up to your basement. As a result, the sewage may come up to the surface through the drain and into your crawl space. This can also happen when sewer lines are clogged.

Leaking pipes

Leaky or damaged pipes running through the crawl space is a very common cause. Burst frozen pipes in the winter can flood your crawlspace quickly.

Poor grading

The slope of the ground around your house should lead the water away from the crawl space. Poor grading can result in water pooling around your foundation walls and finding its way into your crawl space.

Install A Perimeter Drain System

The first step in waterproofing your crawl space is to dig a perimeter drainage channel all along the interior edge of your foundation walls.

The water coming up from the crawl space floor and leaking from your foundation walls can be collected by the perimeter drain system and guided to the sump pump. A perforated pipe is then installed in the trench, covered with gravel to assist with drainage
