What Is Interior Waterproofing?

A Proven Basement Waterproofing Solution for Existing Homes

Interior waterproofing is designed to intercept and control water entering through basement walls, floor joints, or the slab. Installed along the perimeter of your basement, our system collects seepage and channels it into a sump pump for safe removal, keeping your basement dry year-round.

Interior Waterproofing FAQs

Common Questions from DMV Homeowners

Q: Will this stop basement flooding completely?

A: Yes – when properly installed, an interior waterproofing system prevents water from damaging your finished or unfinished basement.

Q: How long does installation take?

A: Most systems are installed in 3–5 days, depending on basement size and scope.

Q: Is interior waterproofing better than exterior waterproofing?

  We had a great experience with DMV Foundation.  I had cracks in my foundation, and I called a number of companies. Each company suggested a different answer to the problem and estimates varied widely.  I ended up hiring an independent engineer to get an unbiased opinion.  The engineer's report tracked what DMV told me precisely.  Amazingly, this was also the least invasive and most affordable solution.  DMV earned my trust. They were honest, fair, showed up on time and did great work.  I highly recommend them.

  I had a consultation with DMV at the strong recommendation of my neighbor and they did not disappoint.  Yos was thorough, responsive, and very patient with all of my questions, including follow up emails.  I particularly appreciated the transparency on cost.  Would highly recommend them to anyone in the market for waterproofing or foundation repair.

They always provide honest, cost-effective solutions and back them up with a skilled team that executes the work flawlessly. Communication throughout the entire process is top-notch. I highly recommend DMV Foundations and will continue using them for all my foundation needs!

  Honestly, I am skeptical of home repair contractors generally. But DMV was absolutely 100% fantastic in every way.  Water was leaking into my basement and I met with 3 or 4 waterproofing companies.  It was clear to me that DMV was different because they were careful before giving their recommendation about how to fix it while the others had the same canned/off the shelf approach that they probably sell to everyone.  They came in and did their work as they promised and it fixed the problem.  I also contacted them in the middle of the night when I thought I had a gas leak and their response was immediate and excellent.  In a market full of pretenders, these guys are serious professionals.  I highly recommend them.

  It would definitely hire DMV Foundation Solutions again if I need to.  They came out and quickly determined the problem and offered a solution.  They completed an exterior waterproofing project and it completely fixed the flooding I had in my basement.
