Basement Waterproofing Photo Album: Waterproofing a Basement in St. Louis, MO

To permanently resolve the basement water issues in this home, our team installed a full sub-floor drainage waterproofing system along with wall encapsulation. The system captures water around the entire perimeter of the basement and channels it to a sump pump, which then safely discharges it away from the foundation through dedicated drainage lines. By intercepting moisture before it reaches the basement floor, the system helps prevent water damage and keeps the space consistently dry. For reliable, year-round performance, the exterior discharge line was equipped with a cold-weather protection system, ensuring effective operation even in freezing conditions.

Sub-Floor Drainage

The darkened strip around the basement perimeter shows where the sub-floor drainage system is installed. It captures water along the foundation and directs it to the sump pump to be safely removed.

Encapsulation

Basement wall encapsulation creates a permanent waterproof barrier that blocks moisture intrusion, inhibits mold growth, reduces musty odors, and improves overall energy efficiency. This process helps protect the home's structural integrity while converting damp basement areas into clean, dry, and usable space.

Sump Pump

The sump pump collects water from the sub-floor drainage system and pumps it up and out of the basement through the white discharge lines.

Water Drainage

Our basement drain systems improve on traditional drainage methods by incorporating a wall flange that allows water seeping through the walls to enter the drain system directly. This design captures both wall and floor moisture and channels it away from the foundation. The system also prevents debris from entering the drainage area while providing a clean, finished appearance at the basement floor.
