"We just had American Dry Basement install a waterproofing system in our basement. We've had issues with water in our basement and needed a total solution so we can sleep at night and go away without worrying about flooding. Steve T from American Dry came to our house and presented us with what the solution will look like and thoroughly explained the entire process. He also answered all our questions and was always available to talk to. He is extremely knowledgeable and an excellent professional to work with. Then Wilson and his two-man crew came to do the work and they were all professional, extremely hard working and respectful of our home. They always started early and worked all day long to get the job completed. They wrapped up all items that were still exposed after we cleaned out most of our basement, used vacuums and filters to minimize all the dust and left our basement cleaner than it was before. We highly recommend American Dry Basement Systems and we're so happy we chose them over the others we received estimates from. And their price was more than competitive for what we believe is a much better solution."

"Ray and his team were incredibly professional, kind and courteous throughout all of the home projects. Their work on my basement foundation, installation of French drains and the rebuilding of an exterior wall were all phenomenal and at a very fair price. I highly recommend their services 10/10"

The first step involved trenching the inside perimeter of the basement slab, which was relatively new and required substantial work with jack hammers (very dusty and noisy). The trench was about 18" wide and 18" deep to accommodate the perforated pipe and the surrounding material consisting of hard plastic "peanuts" to facilitate drainage.  Workmen also installed corrugated plastic on the vertical wall surfaces so that should any water enter higher up on the wall it would be directed into the trench. The trench was then covered with a clear plastic vapor barrier, after which cement was floated over everything and leveled with the rest of the slab.  NOTE: the trenching is very destructive and the workmen will remove any finished elements - baseboard, sheetrock, framing, carpet etc. - to access the walls and foundation. Be prepared to budget repair work on any already-finished areas once the work is done.

The team was invariably punctual, thoughtful and kept the work area clean. Charlie stopped by regularly to ensure the project was moving along as planned and helpful throughout. When finished, the crew cleaned up well and left the site in good shape, although it took some time finally to get rid of the dust.  My only disappointment was that the backup batteries were left in their cases on the floor, when it seemed that they should have been up on a shelf away from harm.

The good news is that our basement has not seen any moisture since the system was installed.  We've experienced some bad storms combining rain over frozen ground and snow and water clearly was getting through the foundation.  We saw the pumps moving significant amounts of water out of the house and the system has been completely reliable.  Finally we were able to finish the basement as we'd hoped because we're confident the drainage system is protecting the investment.

Basement Waterproofing FAQs, answered by experts

Methods include interior sealants, exterior excavation and waterproofing membranes, sump pump installation, and vapor barriers for encapsulation. Techniques vary based on the structure and severity of moisture issues.

A vapor barrier can last over 20 years, but they are vulnerable to pests, flooding, and other natural disasters. If your home weathers a storm or is treated for any pest infestation, make sure to have a drywall pro come check the integrity of your vapor barrier. It’s also important to have a pro install a vapor barrier since improper installation can lead to tears or leaks in the barrier that shorten its lifespan.

Some disadvantages of crawl spaces are mostly regarding the air itself—moisture build-up and poor ventilation, which can cause problems both in the house and underneath it, even damaging the foundation itself. Crawl spaces are difficult to access and often invite unwanted pests during the hot summer months and the cold winter ones. These hard-to-seal spaces are also susceptible to water damage during periods of heavy rain or melting snow.

Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don’t have to worry as much about a fire breaking out as you would with spray foam insulation. 

The foundation repair that will work best varies based on the extent of the damage, the underlying cause, soil conditions, weather conditions, and more. Permanent foundation solutions like underpinning and exterior drainage solutions are better than temporary fixes that don’t address the source of the issue. Some examples of more temporary solutions include mudjacking or slabjacking, waterproof paint, and dampproofing. The best course of action is to have a reliable foundation specialist inspect your issue, treat the underlying problem, and restabilize your foundation.
