Basement Waterproofing Photo Album: Waterproofing an Open Basement

This open basement in Hilton Head Island, SC had water seeping into the basement when it would rain, and the relatively high humidity levels known to the Hilton Head area were coming in the openings. The invading moisture caused mold growth on the subfloor & joists, decreasing the air quality of the living space above. Our team was able to help solve the issue by installing a WaterGaurd drainage system to capture the water and a TripleSafe sump pump to pump it out of the basement. The walls and openings to outside air were sealed with Foamax wall and CleanSpace Vapor Barrier. A SaniDry Sedona Dehumidifier was also installed to monitor and control the humidity level of the air down to a safe 55% relative humidity, stopping mold growth and protecting the floor from wood rot.

Water Flooding in

When it would rain, water would flood into the basement, damaging stored personal belongings and causing mold growth.

White Mold Growth

White mold growing on the joists and subfloor due to moisture & humidity.

Open Basement Humidity

Open basements should be sealed to keep out moisture & humidity. The lattice openings here were letting in humid air & water.

Basement Drain Trench

A trench is excavated around the perimeter of the basement to install the WaterGaurd below-floor waterproofing drain.

WaterGaurd Flow Testing

After installing the WaterGaurd drainage system, the system is tested to assure the water is flowing well to the sump pump.

Custom Work Sealing Opening

Here is one of our team members measuring an open section where gas lines were in the way. This section was customized to maintain access to the gas line switches.

Customized Work Sealing Opening After

Access to the gas line switches was maintained by customizing this section.

WaterGaurd Drainage to Sump Pump

Here is a view showing how the WaterGaurd drainage system connects to the sump pump.

Covering Below-floor Drain

The WaterGaurd below-floor drainage system is concealed under new concrete.

Discharge Line

The sump pumps discharge the water out to where it can flow away from the basement.

SaniDry Sedona Dehumidifier

A SaniDry Sedona Dehumidifier was installed to monitor and control the humidity level of the air down to safe levels.

After Waterproofing System Installation

Here is the final result after having the waterproofing system installed.

Integrated French Drain

At the doorway where water could flow over the concrete, a french drain was integrated into the perimeter drainage system to take in that water as well.
