Methods of Basement Waterproofing

Joseph Coupal - Monday, May 23, 2011

If basement water problems can be solved, you can gain some valuable storage or living space.  There are two ways to go about approaching water issues. The first is to address the leak from the outside of the foundation and the second is to deal with the problem from the inside. From both directions, there are waterproofing techniques designed to seal water out, and others that are designed to divert water from the foundation.

Waterproofing techniques and supplies that are generally used by do-it-yourselfers to seal water out of the basement include spray on sealants, membranes, and injection expanding epoxy waterproofing supplies designed to fill and seal cracks in solid concrete foundation walls. These are some of the least reliable methods of keeping water out because over time, they all succumb deteriorate.

There are also waterproofing supplies and techniques for diverting water on the exterior of the home. Dirt fill can be used along foundation to make the ground slope away from the house. This allows for water to runoff away from the home.

Regardless of the method you choose, exterior repair work is messy and expensive. The installation of anything on the exterior of the foundation will require excavation to expose the wall.

On the interior, the A-1 method of sealing out water from concrete floor cracks is with the gravity fed system. A polymer is used to create a bond between the concrete cracks and fills the entire void through to the bottom. The A-1 preferred method for foundation wall pipe penetration leaks is to inject the gap around the pipe with high-viscosity polyurethane. This polymer can be used on both wet and dry materials, and it can work its way into small hairline cracks to make a more powerful bond.
