Basement Waterproofing

Basement waterproofers are contractors who use specific methods and a variety of materials to eliminate water from penetrating a basement floor or the foundation walls of a structure. Waterproofing may include specially designed drainage pipe, sump pumps, vapor barriers, drains and battery back-up systems all working in combination to ensure water is collected and redirected away from the basement and outer foundation walls.

Over the years there have been 100's of systems designed. In recent years improved research and testing has resulted in new products that when installed properly allow contractors to provide transferable lifetime warranties for homeowners. Of course any warranty is only as good as the company who offers it so be sure to read carefully what is or is not covered and then check with the Better Business Bureau to be sure the contractor you select has an excellent history of how they conduct business.

Top Reasons Your Basement Leaks

When a home is built most builders install a perimeter exterior drain tile system. Typically they put rock around the drain tile to protect it from becoming clogged quickly.  Perforations in the drain tile all water to gather into the drain pipe and then be diverted to an area away from the interior of the basement. This works fine for a period of time, however, eventually dirt makes its way through the rock into the perforated pipe and clogs the system. This may take several years, sometimes much less depending how well the system was installed. In addition, during the building process most responsible contractors will use a variety of coating materials that adhere to masonry or poured foundation walls. View examples of what damp proofing looks like, here.

When either of these initial systems fail a structure becomes subject to water intrusion. The most common causes of a wet basement are:

  1. An existing exterior drain tile that is clogged and can no longer function
  2. Failure of builder to damp proof walls
  3. Structural settlement that causes cracks in the foundation
  4. Hydrostatic water pressure
  5. Poor grading in the yard causing drainage problems
  6. Gutters with downspout extensions that are not long enough to allow water to move away from foundation


Over the years we have seen many homeowners who just live with a wet basement until it comes time to sell their home. Nowadays the inspection and disclosure process will prevent anyone who has not fixed a leaky basement to most likely lose their buyer. Whether you decide to do-it-yourself or to hire a professional you need to make sure that you fix the seepage problem at some point. There are many products on the market that simply do not work very well. A classic example is the paint you can buy at a box store. It may seal up the wall but the water not being collected and diverted so overtime the paint will fail and the problem will recur. In addition, the underlying issue remains so the water will then find the next open source and begin penetration at that porous spot.

How we Stop Basement Seepage

Our team has certified basement waterproofing professionals who have all been through very rigorous training. The key to finding the solution is to fully understand the source of the problem. It can be very tricky. Often homeowners self diagnose the source of a leak when in fact what they are observing is the end result of a problem that may not be readily visible. This is especially true in finished basements. When you ask us to do an inspection (free by the way for homeowners), we'll send out a trained professional who will spend the time necessary to very carefully inspect and assess what is happening at your residence. Once he or she gathers up all the information we'll put in writing for you a complete summary. If repairs are needed we'll outline the cost involved and provide you all reasonable solutions.
