A WhiteCap™ system separates your crawl space from exposed soil, damp air, and moisture that may affect the rest of your house.

A Geochannel system helps move water away from problem areas before it sits inside the crawl space. Instead of letting moisture collect near supports or along the perimeter, this drainage option directs water toward a sump pump or removal point. It’s a helpful part of crawl space repair in Madison, WI, when water intrusion is part of the problem.
The system is installed in areas where water needs a controlled path. Once in place, it reduces standing water, lowers moisture levels, and supports a drier encapsulated space.
Good crawl space repair starts with managing the water source, not just covering the ground. Geochannel will support the rest of the system work better by keeping moisture moving in the right direction. Schedule your inspection today and let our team identify the source of the water.
A sump pump removes collected water before it causes ongoing crawl space damage. It’s especially important in areas that experience heavy rain, snowmelt, or water that naturally collects around the foundation. When paired with encapsulation and drainage, it gives the system a more complete way to manage moisture.
A sump pump is often one of the most important pieces of a moisture control plan. It protects the encapsulation system from repeated exposure to water and reduces the risk of standing water. With the right setup, your crawl space has a better chance of staying dry through changing Wisconsin weather.
