Let Us Design The Ultimate Basement


Basement Waterproofing

Our proprietary system captures water seepage at the trouble spot – right where the wall and floor meet – and doesn’t require any digging or removal of flooring. Our system then channels the water away, diverting it from your home and protecting you from water seepage. It’s simple, yet amazingly effective!

Basement and Foundation Crack Repair

It’s a good idea to find out all you can about the harmful fractures that are affecting your foundation. Basement and foundation cracks are extremely destructive and fixing them is important. This process is a critical step in fixing a leaky basement.

With Real Dry™, water seepage becomes a thing of the past.

Most of the homes and businesses with basements in the United States were built with standard construction practices. That means you have a solid concrete floor with a footing and wall (3 piece foundation) OR you have a monolithic foundation (floor and footing are poured together) and a wall (2 piece foundation).

This means you have a choice when you waterproof. Our proprietary Real Dry™ system captures water seepage at the trouble spot – right where the floor and wall meet – and doesn’t require any digging or removal of flooring. Our system channels the water to a sump pump, diverting it from your home and protecting you from water seepage.

It’s a simple, yet amazingly effective, solution because it’s based on the science of hydrostatic pressure!
