Interior Basement Waterproofing
Interior basement waterproofing systems are installed under the basement floor to relieve “hydrostatic pressure”. This is water pressure in the ground that builds up around your foundation when water has no where to go. Many homeowners have mixed feelings on whether waterproofing a basement from the inside actually fixes the problem. After all, water comes from outside, right? True, but it is not always possible to fix basement water seepage from the outside. If your basement has water under the floor, interior basement waterproofing may be the only fix. Without interior drains, water gets trapped under the floor. This is because your foundation separates the inside from the outside.
When Interior Basement Waterproofing is the Best Option
When you have water under your basement floor, the only way to stop leaks is with an interior drainage system. An interior basement waterproofing system may be the best solution if you have leaking through cracks in your basement floor. Floor cracks that are covered with white powder or heaved up also indicate water build up under the basement floor.
Interior basement waterproofing is a good solution if your walls are dry but you have water seeping in through the seam where the wall meets the floor. Our interior basement waterproofing systems offer a lifetime guarantee against future basement water problems. Our “no nonsense” warranty is free of charge and automatically transfers to future owners.
What to Look Out For
There are many companies offering interior basement waterproofing for wet basements, but they can vary greatly in design and performance. Look out for “channel” drain systems. A contractor will typically install them on top of the footer. The problem with these systems is that they hold water because of being on top of (or next to) a level footer. Only when water fills the trough can it build up movement and make its way to the drain point. These systems require less labor and less trenching so they theoretically should cost much less; however, companies that sell and install these systems often have a special name or patent for them. In reality, any contractor can buy this material, get it made a different color, and make up their own fancy name, so they market it as unique for higher profit margins.
Look For a System That is a True Interior Footer Drain
A true interior footer drain is installed in a trench next to the footer that slopes down hill towards the drainage point, usually a sump pump system. There should be about 1/2″ fall for every 10 feet of drain pipe to promote a good flowing drain. Many municipalities actually require this method.
When to Consider Other Options
If you have wet basement walls at ground through mid level that fade towards the bottom of your walls, an interior system may not be your best alternative. Typically this type of problem is an exterior surface water issue or bad roof drainage. An exterior basement waterproofing system may be the best solution for wet basement walls.
