Read this article about why you should prepare for flooding before it starts

Wet basements not only smell bad, but the presence of mold or mildew can cause respiratory health problems and even trigger asthma attacks. Because water can enter a basement through joints, walls, floors or other means, it is essential to first correctly identify the problem. The next step is to choose the right waterproofing/water management system for the foundation type, and to determine if the best solution is done internally, externally, or some combination of both.

Basement Waterproofing Technologies has over 30 years of experience diagnosing the cause of damp and wet basements, and providing affordable, long-term solutions. Our trained technicians first inspect a home to determine all possible sources of water entry. Once they have fully assessed the situation and established the cause of your damp or wet basement, we will offer you affordable solutions to transform your wet space into a dry, healthier environment. BWT has the in-depth expertise to create a permanent solution to your home’s water issues.
