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?

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.

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.

  I cannot say enough great things about Richard, Nicholas and William - the amazing father and son team that came out today to do some waterproofing work in our basement today. They went above and beyond replacing our sump pump. They rearranged piping to make the space way more functional and usuble compared to the original piping. They were so friendly, answered all my questions and left the space cleaner than they found it. 10/10.

  We had water coming into the basement after recent rains and DMV diagnosed the problem and fixed it for a fair and reasonable price.  Very happy with the work they did and the price we paid.  Definitely recommend!

  DMV Solutions really helped us out by encapsulating our crawl space beneath our sunroom.  The workers were on time and cleaned up very well after the work was done.  We are very pleased with the job.

  After struggling with a poor work done on our crawl space by a national company and no help to remedy even though we supposedly have a life warranty.  We made it a priority to work with a local business.  DMV was wonderful to work with, did't pressure us, explained their recommendation and answered questions in a super timely manner.  Their quote was reasonable and best of all they didn't try to upsell us.

  I am a huge fan of DMV Foundation Solutions.

We recently moved into a new home with a list of items that needed attention. Then, after a heavy rain, we discovered another issue: water was flowing into a basement storage area.

I called four or five foundation companies looking for consultations and quotes, and DMV Foundation Solutions immediately stood out. They were easy to schedule, responded quickly, and were extremely thorough in evaluating our home. They looked carefully at both the inside and outside of the property, reviewed the full report from our home inspector, and helped us think through how to prioritize the different repairs. The entire process felt collaborative and solutions-oriented.

Their pricing was also the best we received, and they offered very supportive financing options. At that point, we were already excited to work with them.

Then we met Richard, Nicholas, and William—the crew that completed the work—and they took the experience to another level.

We were incredibly impressed by the quality of their work, their communication, and just how enjoyable they were to work with. This is easily the best team we have worked with on any repair or improvement to our home. They know what they are doing, take pride in their work, and consistently prioritize service, support, and finding the right solution. And they are fun and radiate the most positive orientation. I feel fortunate to have worked with this team and would explicitly request them by name in the future.

We would happily work with DMV Foundation Solutions again, and I have absolutely no hesitation recommending them.

If you have foundation, basement, crawl space, waterproofing, or related repair needs, I strongly recommend giving this team a call and having the conversation. From the initial evaluation through the completed work, they showed up at every phase of our engagement.

  Man... the job was projected 2+ days. They finished in one. I was also credited on a first job  towards an overall improvement.  They showed up on time, neat, and left the premises as clean as when they came. Big thanks to Richard, William and Nicholas for the hard work from DMV foundations.
