Interior Waterproofing Vs. Exterior Waterproofing

Most homeowners like to utilize their basement and convert it into a second living room for their family to use. A common issue with basements is the vulnerability to water and mold. When water compromises the foundation of the basement, it can lead to cracks and the growth of mold that will affect the health of the residents of the home.  Waterproofing your basement is the important step that every homeowner should do before its too late.

One the first questions you will have to ask yourself is what is the difference between interior and exterior waterproofing

Interior Waterproofing – The two most common methods of interior waterproofing are crack injections and interior drain tile.

Interior Drain Tile- A common way that water seeps into your basement is from the pressure underneath the foundation that causes cracks to develop. We recommend installing an interior drain tile inside the foundation’s footing to alleviate the pressure. This allows the water to be carried off to a sump pump where it is can be removed from your basement.  This interior drain tiles are easy to maintain once installed and will last the lifetime of the home.

Crack injection-  When there is a crack in your foundation your basement will suffer. These cracks can be formed by the pressure that surrounds your basement. The best way to repair a crack in your foundation is by injecting it with expanding polyurethane. The Urethane fills up the crack and expands to the other side of the crack to prevent any future cracks developing from the original crack.

Exterior Waterproofing –  The two most common methods of exterior waterproofing is through using dry sodium bentonite clay and a comprehensive system of foundation protection.

Dry Sodium Bentonite Clay-  One of the simplest ways to fill up a hole or a crack on the exterior of your foundation is by filling it up with Dry Sodium Bentonite Clay. This clay will absorb the water surrounding your crack and harden to become a permanent and pliable seal against any further damage from the crack.

A Membrane with Drain Tile- To protect your foundation wall from exterior water damage, the best option is installing a membrane with a drain tile. This membrane is a coating of asphalt-modified polyurethane that is installed against the foundation wall to create a seal against ground water. The exterior drain tile would be installed outside the membrane to channel water off to the sump pump.

Every home is different, and you should consult with a professional to understand which waterproofing method is right for your home.  If you have any further questions about waterproofing or would like to request an estimate, please give us a call today at 978-262-1405
