In this section of the crawlspace, the existing vapor barrier is torn, displaced, and showing significant wear after years of service. This leaves the soil exposed, allowing ground moisture to evaporate into the air and contribute to high humidity levels beneath the home. Combined with being located right on the waterway, these conditions increase the risk of wood rot, mold growth, and pest intrusion. The solution involves removing the old barrier, sealing gaps, and installing a new, heavy-duty encapsulation system to provide continuous protection against moisture intrusion.
Here we see the home's existing sump pump system, which plays a critical role in managing water intrusion during heavy rains by discharging excess water into the nearby waterway. While functional, the setup shows signs of age and could benefit from performance upgrades. To better protect the crawlspace, we recommend replacing the pump with a more efficient, high-capacity unit, adding a backup battery system to ensure operation during power outages, and inspecting discharge lines for any clogs or leaks. These improvements will work hand-in-hand with a new vapor barrier to create a dry, stable crawlspace environment.
This photo shows newly installed drainage matting, designed to sit beneath a future encapsulation layer. The raised dimples create air channels that help water flow toward the sump pump, preventing pooling and reducing hydrostatic pressure under the vapor barrier. This upgrade works in tandem with the sump pump system to efficiently channel water away, ensuring the crawlspace stays dry even during heavy rainfall. Once sealed with a high-quality vapor barrier, this system will provide long-term moisture defense for the waterfront home.
The final stage of the project features a fully encapsulated crawlspace with a clean, heavy-duty vapor barrier sealing the ground and walls. This barrier locks out ground moisture, works with the drainage matting below, and channels any intruding water directly to the sump pump system. By creating a controlled, dry environment, this solution protects the home's structural integrity, reduces humidity-related issues, and ensures the waterfront property in Ponte Vedra Beach remains resilient against future heavy rain events.
