Job completed for Water Pushing Through Your Foundation? How Crawlspace Encapsulation Solved This Hydrostatic Pressure Problem

Completion date: April 29, 2025

Location: Madison, AL

Why did the customer contact us?

The homeowner contacted us after ongoing issues with water around their foundation had become impossible to ignore. They were seeing standing water collect along the exterior of the home after rains and had been told by another contractor that hydrostatic pressure could be pushing moisture against, and potentially through, their foundation walls. Inside, they had begun to notice damp spots, musty odors, and areas of the crawlspace or lower level that stayed wet long after the weather had cleared. Concerned that this constant water pressure and standing moisture could lead to structural damage, mold growth, and poor indoor air quality, they reached out to us for a professional evaluation and a long-term solution to relieve the hydrostatic pressure and eliminate the standing water around their home.

Solutions provided:

To solve the problems caused by hydrostatic pressure and standing water, we focused on drying the crawlspace and turning it into a controlled environment instead of a damp, exposed one. We began by removing the existing insulation, which had become damp and was trapping moisture against the floor system, creating ideal conditions for mold and wood decay. Once the insulation was out, we applied a Pro Cleaner hydrogen peroxide treatment to the exposed wood and surfaces, helping to clean and treat areas that had been affected by moisture and organic growth. After that, we installed a heavy-duty encapsulation system with a 15-mil floor liner, sealing the ground and isolating the home from the damp soil below. To further protect the space, we custom built a PVC crawlspace door that won’t rot, warp, or absorb moisture, and provides a tighter seal against outside air and humidity. Finally, we installed a Sierra Watchdog NXT 85-pint dehumidifier to actively control humidity levels and keep the crawlspace dry year-round. Together, these steps reduced the impact of hydrostatic pressure inside the crawlspace, eliminated standing moisture, and helped protect the home’s structure and indoor air quality over the long term.
