Water Matrix Blocks installed in lined excavations create weight-bearing underground water storage reservoirs.

Atlantic's Eco-Blox are the strongest water matrix blocks available, capable of supporting over seven tons of distributed load.

With 96% void space, Atlantic's Eco-Blox hold more water in a smaller volume, reducing the overall size of the basin.

Save Labor, time and money on pond-free, rainwater harvesting, and storm water management installations versus gravel-filed reservoirs.

Eco-Blox lock together quickly and securely, easily supporting landscaping, pavers, gravel, or sod for great design versatility.

Arrange modular blocks in any configuration and any number of levels to accommodate almost any basin.

Excellent for bog construction to create settling chambers below natural plantings of active bog filters.

Eco-Blox have been tested and approved for compliance with the American Association of State Highway and Traffic Officials (AASHTO) HS-20 standard with a minimum safety factor of 200% for every condition and depth calculated. Independent testing in a machine press demonstrated Eco-Blox supporting over 15000 lbs before failure. Testing results available upon request from Atlantic Water Gardens.
