Basement Waterproofing FAQs

What Is Hydrostatic Pressure?

Hydrostatic pressure is caused when water pressure builds up outside a foundation. The weight of the water pushes downward until it finds the path of least resistance, and since a crawl space / basement is nothing but a hole in the ground it is easy to see why it would come in the small seam at the floor / wall seam.
It is usually recommended to discharge the water at least 10 feet or more away from the foundation. We accomplish this by installing an anti-freeze device and a solid pipe out to a yard drain. This pipe is buried underneath the sod and is hardly noticeable. 

cWhat Is GrateDrain™?

GrateDrain™ is a dual chamber system that is designed to accept ground water faster than any other drainage pipe on the market, yet it is placed just under the floor in front of the footer. This design allows ground water to only be pumped if water is going to come on the crawl space or basement floor and doing so quickly when called upon to work.

What Is GrateSump™?

GrateSump™ is our specially designed sump pump collection system. It was designed by someone who installed thousands of sump pump systems over the years. It is not as deep as other sump liners on the market and it will not encourage undermining of the foundation. We use our FastSump to pump the ground water out and away from the foundation.

We are in business to create healthy, livable spaces for North Carolina families. There are many ways to lower the humidity in a basement or crawl space. Dehumidifiers are a good start, and can greatly alleviate moisture issues. Unfortunately, they are rarely enough to solve the problem.

We typically start by installing a wall vapor barrier along with a ground water control system to reduce the amount of moisture that enters. Because condensation forms on cold surfaces in the late spring, summer and fall months, a dehumidifier is typically still necessary to ensure a clean and comfortable space all year round.

Contact us at 919-289-8381 to have one of our experts assess and recommend the ideal moisture control option for you.
