Our Proven Method for a Dry Basement

Our process permanently eliminates basement water damage, even under the most severe conditions. This innovative solution stops all water and moisture infiltration in your cellar, generally within a single day. Former areas that were previously unusable due to water and moisture infiltration will be transformed into clean, dry, and 100% odor-free spaces, preventing mold from thriving.

Unlike conventional basement waterproofing companies, our method provides a permanent seal without ever needing a sump pump or any other mechanical means to dispel water. All corrections are done from the inside, meaning there is no external digging or ground disturbance.

This technology is the same trusted solution used to waterproof major infrastructure projects, including the Chunnel (the tunnel from Great Britain to France), the Mid-Town Tunnel, and numerous other transportation hubs. Our sealed membrane process is engineered to last longer than the concrete surface it is sealing.

A Superior, Science-Based Approach

Conventional Basement waterproofing methods often cost thousands of dollars and work by bringing water into your home’s envelope to be expelled by mechanical means. This approach surrenders to water infiltration rather than stopping it.

The method we employ seals all moisture with a durable membrane. The new waterproofed surface, less than one inch thick, can withstand pressures in excess of 12,000 P.S.I. This process is also approved by the U.S. Department of Agriculture (USDA) for use in food treatment facilities, highlighting its safety and effectiveness. Under the most severe water infiltration conditions, our solution ensures all water is permanently eliminated.

Unmatched Value and Trust

If you have researched the cost of Basement waterproofing services, you know that prices typically exceed $4,000. These methods often involve disruptive digging for a French drain or installing an evacuation pump—solutions that manage water but do not stop it. 

Our method provides a superior sealing process that stops water with a permanent bond. The process produces no VOCs (Volatile Organic Compounds) and has no negative impact on the ozone layer. Starting at just $1,299, you are getting a permanent and highly effective solution for a fraction of the cost.

We have never had a single complaint from a residential or commercial client about the reappearance of water after our service. Our results are a testament to the effectiveness of our process.
