Introducing Crawl Space Drainage Systems: Keep Your Home High and Dry

Posted on June 27, 2024

Don’t let your home go down the drain! A crawl space drainage system is essential to maintain a dry and healthy home environment. Proper drainage prevents moisture from accumulating in the crawl space, which can lead to structural damage, mold growth, and poor air quality. Installing an effective drainage system protects your home and enhances its life

How does a crawl space drainage system work?

A crawl space drainage system works by collecting water and redirecting it to the crawl space through a combination of drains, sump pumps, and vapor barriers. The system ensures that any water that enters the crawl space is drained properly, keeping the area dry and free of moisture.

Types of Crawl Space Drainage Systems

Internal French plumbing system

An internal French drain is installed along the crawl space floor. It collects water that flows through the foundation walls and sends it to the drainage outlet. This system is highly effective in preventing water from accumulating in the crawl space.

Exterior French Drain system

Around the outside of the foundation is a French exterior system. Before the water reaches the crawl space, it stops and directs the water away from your home. Such systems are useful in areas with high groundwater levels or high rainfall.

Sump Pump System

A sump pump system is an important part of crawl space drainage. It collects water from a drainage pipe and pumps it to a safe distance outside the house. Sump pumps are especially useful in areas where flooding is common or high water levels are high.

Gravity Drain System

Gravity drainage systems rely on the natural gravity of the soil to direct water away. This system uses a mechanism to direct the water downward, preventing it from pooling around the base. Gravity drainage systems are a cost-effective solution for suitable properties.

Surface Drain System

They are designed to collect water and drain it away from the crawl space. They are ideal for handling runoff from rainfall and irrigation.
