As a crawl space repair company in South Carolina, we help property owners repair crawl space drainage problems. If you’ve seen standing water or stains on the walls, floors, or soil of your crawl space, there’s a very good chance that you need a drainage system. In a soil-bottomed crawl space, water can trickle in from the dirt, making the ground a huge muddy wreck. If water drips into a concrete-bottomed crawl space, it usually makes its way in through tiny cracks in its flooring or gaps that exist in-between the floor and base wall.

Nearly all problems that crop up with a crawl space are attributable to damage from water and extreme humidity. A damp or flooded crawl space can cause a high amount of undesirable water or water vapor to enter your home on a daily basis, eventually resulting in soaked insulation, deterioration of structural wood, and the development of mold.

During rainstorms or floods, water can seep into a crawl space by way of its vent openings and entranceways. Plumbing-related leakages and excessive condensation levels are other ways moisture can infiltrate a crawl space.

Regardless of how water makes its way into a crawl space, you must attempt to drain it out in order to keep the area dry. A moisture-free crawl space isn’t susceptible to mold or mildew, two very common fungus species that induce wood decay and drastically reduce the air quality inside your home.

Keeping a Crawl Space Dry With a Water Drainage System

The amount of moisture in a crawl space may be diminished and prevented once the cause of the water intrusion is dealt with. A good crawl space drainage system is the most effective (and very often only) remedy for heavy groundwater leaks.

The kind of drainage system you should use for a crawl space will depend on how it’s built and what condition it’s in. At least a few of the following elements will need to be included in an efficient system:

Drainage Pipes

Drainage pipes are ideal for collecting moisture from crawl spaces with dirt floors. SmartPipes are especially popular for this purpose for their built-in fiber optic monitoring feature, which enables them to detect leaks and any erratic pipe movements or obstructions that may cause a leak. For crawl spaces that have cement floors, unobtrusive DryTrak or WaterGuard drainage channels that redirect water to a sump pump are advisable.

Sump Pumps

If your crawl space drainage lines cannot be rigged up to divert water away from your home’s foundation, you’ll need a sump pump system. The lines of these systems redirect water into a sump tank that’s built into the floor of the crawl space. From there, the pump expels the water to an outside location when the water level in the sump pit is high enough.

Drainage Mats

These indented rubber or vinyl matting products are usually laid down in a dirt-bottomed crawl space to set up a drainage area that guides water into your drainage pipes.

Waterproofing Barriers

These resilient water membranes are installed as part of a crawl space encapsulation system. It works to deflect water into your crawl space’s drain pipes while maintaining a dry crawl space interior.

Vent Holes and Doors

To protect against water leakage through your crawl space vent openings and doors, you should seal off these holes with water-resistant covers that have fitted gaskets, like EverLast vent covers and doors.

The Benefits of a Full Crawl Space Water Drainage System

A comprehensive encapsulation system doesn’t just prevent water from accumulating in a crawl space; it also ensures that groundwater levels stay beneath the crawl space grade. A water vapor filter is typically installed above the crawl space’s grade to keep ground moisture and water vapors at bay. This type of waterproofing system is very efficient at controlling ground water and keeping your crawl space dry and mold-free.
