Crawl Space Drain Services
Guardian Foundation Repair Offers Crawl Space Drain Installation and Solutions.
Crawl space drains are installed to remove excess moisture and standing water in your crawl space. A crawl space drain is a great alternative to exterior excavation and waterproofing in hard-to-reach areas. In order to maximize the effectiveness of the crawl space drain, a vapor barrier or encapsulation system needs to be added to help reduce the moisture levels and improve air quality in the crawl space.
What is a crawl space drain?
Crawl space drains are 4” corrugated perforated pipe with a sock cover, installed along interior footer to carry water to a sump pump or low spot allowing gravitational exit. The Drain is back-filled with gravel and in some cases masonry weep holes are needed in block wall to relieve hydrostatic pressure and allow water to enter drain system.

Common Questions About Crawl Space Drains
What is a crawl space drain?
It is a four inch corrugated perforated pipe with a sock cover, installed along the interior footer to carry water to a sump pump or to a low spot where it can leave by gravity. The drain is back filled with gravel, and in some cases masonry.
Why choose an interior drain over digging outside?
A crawl space drain is a good alternative to exterior excavation and waterproofing in hard to reach areas. Some houses simply do not have the access around the outside to excavate, and on those a properly installed interior drain does the job without tearing up what is above ground.
Does a drain by itself fix a damp crawl space?
Not completely. The drain removes standing water, which is the first job. To get the full benefit you also need a vapor barrier or an encapsulation system, because that is what brings the moisture levels down and improves the air quality under the house.
What is the sock on the pipe for?
It keeps soil and sediment out of the perforations so the pipe keeps draining years after it goes in. A perforated pipe without a sock silts up over time, and a clogged drain does nothing for you.
