SuDS Retrofit Solutions

Hydrorock delivers unmatched flexibility in design, installation and application – ideal for complex projects with multiple functional requirements and where residents or site users are already present.

Installation is significantly simpler and faster. Compact excavations reduce disruption, minimise vehicle movements, eliminate the need for extensive shoring and lower the number of personnel working in the ground – improving on-site safety.

The modular nature of Hydrorock allows for custom layouts using small, interconnected blocks that easily adapt to irregular, narrow, or otherwise challenging site conditions, all while minimising disturbance to existing occupants.

Crucially, the system offers real-time adaptability: if unexpected underground obstacles are encountered, the design can be adjusted with minimal delay. This design agility stands in stark contrast to traditional systems, which require large, inflexible, highly disruptive excavations.

Routine maintenance-free lifetime system integrity

Not only is Hydrorock, fast, flexible and safer to install, once installed, it’s extremely efficient, requires no routine maintenance, keeps water clean and on site, and maintains local nutrient neutrality.

• A solid structure, with a loading strength of up to 4,000 kg per m², Hydrorock systems prevent the risks associated with solutions that create underground voids.
• The geotextile membrane wrap stops root penetration and soil influx keeping the natural aquifer blocks intact and structurally sound.

Because of these properties, there is no requirement for routine maintenance and the lifetime integrity of the whole system is ensured, with consistent operational performance maintained.
