Bentonite water proofing known as the’Bath tub’ at the World Trade Centre was built around the foundations to prevent the Hudson river from flooding the building. There was real fears that if the Bentonite structure would subside it would flood the basement & also the Subway rail system that was directly below the twin towers. Thousands of lives were saved in the hours after the attack because the ‘bath tub’ held strong.
Underground Tankless system has used Bentonite clay liners since 2008 as part of the water proofing system that has stood the test of time through earthquakes, floods & droughts.
Unlike many modular underground storage systems, which can become buoyant and require deep excavations or additional pumping infrastructure, the Tankless Engineered Urban Aquifer uses perforated coils that naturally sink and lock into place within the aggregate.
By working with gravity rather than against it, Tankless simplifies installation while creating opportunities to harvest and store more water beneath urban landscapes.

Patented design with gravity discharge when full & load bearing system removes the hidden installation costs of underground tanks significantly.
