When a crawl space is left open to the ground, it acts as a constant source of humidity that can cause floors to sag and mold to grow. Professional encapsulation stops this process and ensures your foundation remains stable and healthy.
The first step in the encapsulation process is to create a protective barrier. We apply a reinforced polyurethane liner to your foundation that creates an impenetrable shield against ground vapor and liquid water.
The WhiteCap™ liner is much more durable than standard vapor barriers found in big-box stores. This specialized membrane is the most effective way to keep your crawl space dry for decades.


When it comes to crawl space encapsulation in Oshkosh, managing groundwater often requires the installation of GeoChannel tracks before the encapsulation liner is permanently secured.
Installing this drainage system prevents water from being trapped between the liner and the dirt, which can lead to odor and structural instability.
With over 30 years of professional experience, our crew at Acculevel in Oshkosh knows how to install and maintain sump pump systems. We'll make sure the area under your home stays dry during the rainy season by installing a sump pump that quickly and reliably moves water.
Your home or business foundation will remain protected against flooding and excessive moisture year-round after integrating these mechanical systems.
