Have you ever ventured into your home’s crawl space? Many homeowners rarely, if ever, go into these areas underneath their houses. They know, or at least have a feeling, that the crawl spaces are nasty and unhealthy, so they stay away. It is out of sight and out of mind, even though it shouldn’t be.
Whatever is in your crawl space air and environment also is in your house affecting you. This is because of the stack effect. Air, vapor and moisture are drawn up through the house in an airflow pattern from bottom to top.
Dirt and gravel crawl spaces are cheaper than concrete floors, but they also create dysfunctional homes. This exposed, damp earth contributes a lot of water vapor into the crawl space air. Groundwater can seep into the crawl space through the walls, floor, or open vents or access doors. Then it saturates the crawl space floor, forms puddles and slowly evaporates upward into the house.
Other negative effects associated with damp and wet crawl spaces include:
To prevent these nuisances and keep water out of your crawl space, it is important to have an effective drainage system. The best way to intercept seeing water is with a system that collects water from the perimeter walls and floor. Ohio Basement Authority installs the CrawlDrain system to do just that.
CrawlDrain is similar to BasementGutter, our basement drainage system. Like BasementGutter, CrawlDrain sits in the sub-floor of the crawl space, but it is specifically designed for dirt and gravel floors as opposed to concrete. CrawlDrain’s custom design features holes on the top and front under a filter fabric to accept water from the soil and the surface of the crawl space. There also is a special flange with spacers on the back, as well as large holes to accept water from the crawl space walls and wall joint.
While this reliable system works to collect seeping water, this water needs somewhere to go other than your crawl space floor. Any of our trustworthy sump pump systems can be installed in conjunction with CrawlDrain, but the system designed specifically for crawl space waterproofing is the SafeDri Pro. A high-quality 1/3 hp cast iron Zoeller pump sits inside the sump liner atop a special stand. This special stand keeps the pump out of any silt and sediment that may wash into the sump liner.
This system also has a two-piece airtight lid that allows for easy access, and so any water sitting in the sump hole doesn’t constantly evaporate into the crawl space. The lid and unique sump liner also are designed to accept the CrawlSeal encapsulation system for an airtight seal.
