AquaCrate 400L Storm Soakaway Crate

Durable and Efficient Rainwater Management Solution

The AquaCrate 400L Storm Soakaway Crate effectively manages rainwater runoff, reducing flood risk and preventing waterlogging. Built for heavy-duty applications, this high-capacity, load-bearing crate quickly absorbs and disperses surface water into the ground, supporting even HGV traffic loads. With a modular, UK-made design, it offers adaptable installation options to meet a variety of site requirements. Crafted from recycled polypropylene, the AquaCrate 400L is an eco-conscious, SuDs-compliant solution for sustainable stormwater management.

Key Features

• High Load-Bearing Capability: Supports up to 100 tonnes/m², handling light to heavy-duty traffic, including HGVs.
