Atlantic Water Gardens Eco-Blox are modular water matrix blocks designed for pond-free basins, bog filters, rainwater harvesting and stormwater management. Each assembled block stores a large volume of water in a compact footprint while supporting landscaping and hardscapes above the reservoir. Compact high-capacity design: Assembled dimensions of 27" L x 16" W x 17.5" H with 31.5 gallons of storage per block and up to 96% void space. Exceptional strength: 8-panel construction with lateral supports; independently tested to withstand over 14,000 lbs and engineered to meet AASHTO HS-20 loading criteria. Versatile installation: Slide-lock connection system lets blocks lock together securely; arrange in any configuration or number of layers to fit site requirements. Gravel-compatible openings: 1/2" x 3/4" hole pattern accepts smaller gravel for filtration or planting media where required. Multiple applications: Ideal for pond-free waterfalls, bog construction, settling chambers below plantings, rainwater harvesting and stormwater detention. Durable and tested: Impermeable liner use recommended for lined excavations; Atlantic provides a 1-year limited warranty. Eco-Blox save excavation time and reduce basin size compared with gravel-filled basins while supporting landscaping, pavers, gravel or sod above the reservoir. Use lined excavations and follow the Eco-Blox installation manual for best performance and long-term reliability.
