Interior Waterproofing in the DMV
Stop Basement Leaks and Flooding Before They Start
Our proven interior waterproofing systems collect and redirect water before it reaches your basement floor – protecting your home from flooding, mold, and costly water damage.
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.


Moisture Barrier Protection
Our airtight dimpled drainboard stops wall seepage and prevents mold growth.
Perimeter Drainage Channels
Capture water at the wall-floor joint and beneath the slab.
Direct Sump Pump Connection
All collected water flows to a high-capacity pump for removal.
Non-Clogging Design
Built for long-term performance with minimal maintenance.
Custom Fit for Every Basement
Designed around your unique layout and water issues.

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?
A: Interior systems are ideal for existing homes where excavation isn’t possible. Exterior systems are best for new builds or when the foundation can be accessed from outside.
Q: Will you have to dig up my entire basement?
A: No – our process involves narrow trenching along the walls, minimizing disruption to your space.
Q: Do you offer warranties?
A: Yes – our systems come with lifetime, transferable warranties.

lina naik2025-09-12 Russell was amazing in pinpointing our water issues! Ravi Khanna2025-09-12 Russel was thorough and personable! Great company! Michael Penn2025-07-31 Thanks to Geoff, project Mgr., and his crew of T & Morisio (sp). The latter graded and sculptured a difficult gravel driveway that turned and twisted. These guys, without any grumblings, went over their work, at my request, several times to even out the smallest of imperfections. Geoff, without asking, adjusted the cost as the scope of work was less material and labor intensive. I would reach out to DMV again. And, they were always responsive to voice and email. Very professional. Michael Julie Witsken2025-07-25 We called DMV to assess what else we might need to do to waterproof our basement after a couple incidents of water in the basement after heavy rain. Russell came out and spent over an hour with us reviewing our situation. He was extremely knowledgeable and helpful. In the end, he advised that there were a couple of relatively simple things we could do that unfortunately for DMV did not require their services. We are very grateful for his honesty - many other companies would have gladly recommended and charged us for work we didn’t need. Even though we aren’t using DMV at this time, they will be our first call if anything ever changes, and we will recommend them without hesitation to anyone who could use them. Heidy Lopez2025-06-26 Awesome team of professional workers and very Knowledgeable! We look forward to working with them in future projects. Laura Smalligan2025-06-24 We had a crawl space filled with construction debris we wanted encapsulated and some window wells that were starting to crack. DMV Foundations did a great job from start to finish! Everything was very smooth, the crew was super friendly, and the project was completed on time. Highly recommend! Charles Snyder2025-06-24 Quick and honest evaluation of our home. Not trying to upsell us on anything. Thanks! Melinda Jackson2025-06-11 The guys who worked on our foundation were OUTSTANDING!! They arrived early each day and were very professional. I would recommend DMV Foundation Solutions for any basement or water problems you may have in your home or business!! R.
