Crawl Space Perimeter Drain
A perimeter drainage system works by capturing and navigating the water from the crawl space dirt floor, foundation or walls to a sump pump via underground pipes along the perimeter.
By installing an interior drainage system you’ll be capturing the water at it’s most common entry point while avoiding clogging from soil and roots with exterior versions.
For a dirt floor crawl space – The system features a filter fabric with holes on the front and top to accept the water from the soil.

Membrane for Crawl Space
One of the best ways to protect your crawl space is with the help of a waterproof membrane or vapor barrier. This plastic sheet’s material usually 20 millimeters thick is responsible for permanently preventing moisture, outside air and pests from entering.
This waterproof membrane vapor barrier is laid across the entirety of the crawl space floor and up the walls. This barrier works in conjunction with drainage mats, insulation and vent covers.

Sump Pump and Basin
If water penetration is serious a sump pump might be a necessity. These machines are designed to move water out of your home. We recommend a pump with a high-quality 1/3hp Zoeller pump which is found in most other pump packages. A crawl space drain is usually attached to a sump pump to remove water after collection.
Flood Alert System: Built into some of the lids is a water-sensitive alarm. This alarm will alert you if water has reached the top of the sump pump’s lid. This can most definitely save you from a huge water disaster.
Vapor Barrier Integration: The vapor barrier used for crawl space encapsulation only works if the area is air tight. That is why a sump pump with a special lid that integrates with vapor barriers for an airtight fit is important. If bunching in the membrane were to occur this can allow for water to pool and not be able to reach the drain.

Dehumidifier
After insulating and encapsulating your crawl space, the next step for waterproofing would be to install a dehumidifier. The tricky part is finding one small enough to fit but strong enough to remove upwards of 90 pints of water a day. Not mention your crawl space is often cold so this dehumidifier needs to work efficiently in lower temperatures.
Crawl space dehumidifiers are a key addition to your crawl space if you want to keep moisture and mold growth down. Installing a dehumidifier in your crawl space has many benefits. It creates drier conditions, improves indoor air quality, and lowers the chance of future mold growth. This helps to keep your home a clean and breathable place to live.
Please note that you’ll want to talk with an expert about what type of dehumidifier to install. You’ll want to factor in square footage in order to get the best results. See our list of best crawl space dehumidifiers here.
