Aquascape AquaBlox Modular Water Storage System Small — 17‑Gallon Stackable, Load‑Bearing Block

Built from recycled materials and designed to compress large volumes of water into a compact footprint, the Small AquaBlox (26.5 x 16 x 9.5 inches) stores about 17 gallons while supporting heavy loads above. Its interlocking, stackable design replaces bulky gravel basins, reduces liner and underlayment needs, and shortens installation time for both landscape professionals and DIYers.

How does AquaBlox increase storage compared to a gravel basin?

The small AquaBlox stores roughly 7.4 gallons per cubic foot, delivering over three times the water-holding capacity of an equivalent gravel volume. That means you get significantly more usable water inside a much smaller reservoir, reducing how often you need to top off for evaporation.

• Holds 17 gallons in a compact 26.5 x 16 x 9.5-inch block
• Approximately 3x more storage than gravel for the same footprint
• Less evap-related topping off and lower maintenance frequency

Can AquaBlox support landscaping and foot traffic above the reservoir?

Yes — the load-bearing top is engineered to handle heavy surface loads, making it suitable under pathways, patios, and planted surfaces. The durable construction maintains structural integrity while keeping the water storage compartment clear and functional.

• Top rated to withstand up to 5,472 pounds per square foot
• Ideal for buried installations beneath hardscape or soil
• Designed for long-term, trouble-free performance

What benefits do AquaBlox offer during installation and upkeep?

AquaBlox arrive as a complete assembly — top, bottom, two sides, and four supports — so you spend less time on placement and need less liner and underlayment than with loose rock. The open, molded cavities are easier to clean, less likely to clog, and simplify routing of plumbing and overflow lines.

• Modular sections interlock for quick assembly and flexible sizing
• Reduces liner and underlayment materials and labor costs
• Smoother internal surfaces resist debris buildup and clogging

Where can AquaBlox be used besides pondless waterfalls?

Beyond Pondless Waterfall reservoirs, AquaBlox are well-suited for RainXchange rainwater harvesting systems, stormwater detention, and any landscape application that needs hidden water storage. Their modularity lets you combine multiple blocks for larger capacity or stack them where vertical space allows.

• Compatible with RainXchange and rainwater capture projects
• Stackable and modular for scalable storage solutions
• Reusable recycled material construction suitable for landscape use

Who is this for: The Aquascape AquaBlox Small is aimed at landscapers, water-feature installers, and homeowners who want efficient, low-maintenance reservoir storage without expanding excavation size. It’s especially useful when space is limited, when you need reduced installation labor or materials, or when you want a reliable, load-bearing water storage option hidden beneath garden surfaces.
