Waterproofing in Tight Spaces

Waterproofing a wall fracture in an extreme tight area.

Waterproofing experts with over 30 years of leak solving techniques. This example of a recent repair shows a long term leak with mold growth as well as soil entry. This was repaired by injection of SP-3. While the tight working area was difficult, we were able to shut off the entire leak.



Mr. Sponge Waterproofing Incorporated specializes in stopping water from entering through poured cement foundation walls. We repair wall cracks, tie rods, honeycombs, and I-Beam leaks by injecting our proprietary SP-3 Water Activated urethane, under high pressure, into the path of water entering your basement. We instantly stop water entry in these most common basement leak sources.

Mr. Sponge is owner-operated; this means you get the owner on every job. We are not a franchise operation, but rather a Michigan-based corporation that brings solutions to homeowners from a local source.

Developed in 1996, our proprietary blend of SP-3 urethane brings a high performance in water-activated sealing solutions for our customers. Over the last 20 years, both private and commercial clients have seen their basement leaks disappear. On the commercial side of our business, we have clients with two decades 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.

If you are looking for a specialized owner-operated company to fix your leaks, you have found your solution in Mr. Sponge. We look forward to helping solve your basement leak problems.
