Solutions For A Flooding Basement

There are a variety of causes for a leaking or flooding basement. In the video below, you can learn how we can remedy basement flooding due to a high water table.

Foundation Waterproofing Solutions

What is a water table?

“Water table” is the level at which the soil is saturated with ground water. High water tables usually occur near rivers, lakes, marshes, and naturally occurring aquifers. When the water table level is higher, usually in the spring or after heavy rain, water can push up through the floor and cause basement flooding.

Even if your basement is flooding due a high water table, our expert solutions will keep your basement dry.

Although foundation cracks may be common, but they are also the most easily repaired foundation concern.

Foundation leaks due to a crack in the foundation are often the result of foundation movement. Due to this, repairs must be flexible enough to withstand future foundation movement to ensure a permanent repair. DrySeal® crack repairs offer exactly that- permanent foundation waterproofing.

Encapsulation Membrane

Our expert solutions use foundation membranes in a variety of ways to prevent foundation leaking. Antimicrobial materials offer a clean, water-tight solution for porous foundations and widespread foundation leaks.

Foundation membranes can also be used to encapsulate a crawlspace, making the best use of your crawlspace storage.

Sump Pumps

We can’t blame anyone for cringing at the mention of a sump pump. But the truth is that they are the best solution for a high water table situation. Our experts can diagnose if a sump pump may be necessary to prevent your basement leaking. Sump pumps are often used in addition to other foundation waterproofing products to ensure all water is channeled to the pump and safely out of your basement.

Have peace of mind that your sump pump is operating correctly with the use of a back up battery and high water alarm so your basement never floods again.
