Hydrorock is a natural aquifer system that’s installed under the ground. Made from natural mineral wool, it soaks up rainwater when it’s wet and then releases it slowly over time. It also irrigates the plants in the garden above, reducing the need for watering using mains water. At Juniper Road we have installed Hydrorock systems throughout the outside areas, collecting the water from the front section of the roof and porch. All systems are cleverly linked to provide resilience from surface water flooding and provide a water source for plants in the gardens.
