Mr. Sponge Incorporated has its origins in a family-owned firm that was founded in Detroit Michigan in 1967. Basement Waterproofing was just one of the commercial construction activities the firm offered. In 1995, Mr. Sponge Corporation was created, built on the 28 year history of the previous firm but totally focused on basement waterproofing with polyurethane injection processes.

  • We remain current in our field by maintaining memberships with nationally recognized building associations and participating in seminars and workshops that enhance our skills.
  • We are a licensed builder.
  • Our latest invention is the TRX Compressed Swell Plug developed for homeowners to repair their own tie rod hole leaks.
