A waterproof system will protect your home from cracks caused by water, settling and expansion/shrinkage in the summer and winter. Over 40% of new homes have water problems within the first three years after construction. By law, builders only have to provide a two-year warranty, so be sure to check the fine print of your purchasing agreement.

Water damage only gets worse the longer that you leave it. Water leaks will penetrate your foundation, slip into cracks and slowly break them down — something people often forget is that concrete is porous. Although it is expensive to repair, the value of your house will drop a lot farther in price if there is water damage. Another factor that water damage brings is mold, which can create possible health hazards for you and your family.

Any new residential construction can be waterproofed the right way because the foundation is exposed. The most cost-effective way is to spray a rubberized coating onto the exterior walls. This fills in all the areas of the walls and acts as a membrane, keeping water out. It can be done by the ‘do it yourselfer‘, but you need to do your homework and seek some expert advice beforehand. Other products include cementitious and sheet membranes, hot tar or bentonite. Make sure you get several quotes and recommendations in regards to the leakage.
