Aquascape AquaBlox® Pond Boxes
High-Load Modular Reservoir System for Ponds & Water Features
 
Aquascape AquaBlox® Pond Boxes are a professional-grade, modular solution for creating underground water reservoirs with exceptional load-bearing capacity.
Designed to maximise usable water volume while supporting heavy surface loads, AquaBlox are the preferred choice for fountainscapes, spillway features, swim ponds, and bespoke water storage systems.
This is infrastructure you build once—and rely on for decades.
 
Why AquaBlox® Are the Industry Standard
Extremely high load rating – supports paving, stone, and large features
Maximum water volume – minimal void loss compared to crates
Modular design – scale reservoirs to any size or shape
Fast on-site assembly – no specialist tools required
Used extensively in commercial and high-end residential projects.
 
Strength Without Compromise
Each AquaBlox® box is engineered to carry serious weight:
Load capacity: 7,300 kg per box
Distributed load: up to 28 tonnes per m²
Despite this strength, the open internal structure maximises water storage, making AquaBlox ideal where volume and strength both matter.
