A smarter way to manage water below ground

Managing rainwater effectively is becoming more important, whether you are dealing with surface water in a garden or designing drainage for a large development.

Hydrorock offers a different approach. Instead of hollow plastic crates, it uses engineered stone wool blocks to store, filter and release water. The result is a system that works with water naturally, rather than simply storing it and moving it elsewhere.

Go beyond traditional soakaways

Standard plastic attenuation crates are designed to hold water temporarily, but they offer little in terms of filtration, irrigation or long-term environmental value.

Hydrorock is different. Its structure allows water to be stored, gradually released into the ground and retained where needed to support planting. This creates a more balanced approach to water management.

It can be used for

• Attenuation to reduce peak flows
• Infiltration to return water to the ground
• Irrigation to support planting and green infrastructure

Built for flexibility across projects

No two sites are the same. That is why Hydrorock is available in a range of block types with varying densities and performance characteristics.

This means it can be configured for

• Light-use areas such as domestic gardens and landscaped spaces
• Areas with occasional foot traffic
• Heavily trafficked zones such as roads and highways

Whether you are a homeowner installing a rain garden, or an engineer designing for a major scheme, the system can be tailored to meet your specific requirements.

Supports sustainable drainage and biodiversity

Hydrorock fits naturally into SuDS strategies and nature-based solutions.

By enabling infiltration and supporting planting, it helps create systems that do more than manage water. It contributes to healthier landscapes, more resilient urban environments and improved biodiversity outcomes.

This makes it particularly valuable for projects targeting sustainability goals or biodiversity net gain.

A lower impact alternative

Plastic attenuation crates are widely used, but they rely on fossil-based materials and typically serve a single purpose.

Hydrorock offers a more sustainable option. It reduces reliance on plastic while delivering additional functionality, helping you meet environmental targets without compromising on performance.
