How to Waterproof a Basement Yourself:

How to waterproof a basement with the SquidGee Dry System

Hiring a professional to waterproof your basement is expensive, which leads many homeowners to look for alternatives like waterproofing paints or hydraulic cement to plug the leaks. Paints, patch-its and plug-its are band-aids to a wet basement that cause greater hydrostatic pressure build up in foundation walls. If you’ve used these methods before you know it’s only a matter of time before the seepage finds a new location to enter your basement. The most common source of basement water seepage is through the joint where the floor and walls meet (known as the cold joint). Hydrostatic pressure builds up around a home’s foundation and forces water into the basement.

The first step in basement waterproofing always starts outside the home. Look for any low spots around the foundation that pool with water. Fill in those low spots with soil to direct water away from the foundation. Managing the water outside the home is a preventative step against a wet basement – this also includes installing gutters on your home and being sure your downspouts carry the roof water at least 8 feet out from the foundation.

The next step in do-it-yourself basement waterproofing is installing the SquidGee Dry interior waterproofing channel to collect and manage the seepage. To start, measure your basement and get a quick quote for your DIY project using our cost calculator. Place your order online and we’ll deliver your custom DIY basement waterproofing kit and step-by-step installation guide right to your front door!
