Panel Drain Waterproofing

Draining a wall crack into the floor

Old Style waterproofing allows for Mold Growth


This example is a typical older style waterproofing method. It consists of cutting the floor to allow the wall crack to drain behind the panel. It allows the water to continue to enter the basement environment which allows for mold growth as seen in photograph. We repaired this properly by removing the panel, then injecting with SP-3 which stopped the water from entering the basement.


Mr. Sponge’s proprietary blend of SP-3 urethane was developed in 1996 and brings a high performance in water-activated sealing solutions for our customers. In more than 20 years of testing and application for both private and commercial clients, the continuous result is the disappearance of basement leaks. On the commercial side of our business, we have clients with over 20 years of history with Mr. Sponge who continue to use our sealing techniques and services today for their numerous properties.

On the national level, we have developed the first and only tie rod leak repair device, which allows homeowners to fix their leaking tie rod holes on their own time. Currently sold in 35 states, the TRX Compressed Swell Plug has continued to grow on a national scale.
