Hydrorock - Model Type D -Rainwater Drainage & Buffer System

Efficient Rainwater Buffer
Hydrorock® is a new type of rainwater buffer that stores more rain and groundwater but requires less digging. As a result, Hydrorock blocks offer more water absorption and more efficient infiltration and drainage.

APPLICATIONS

• Drainage to prevent flooding on pavings, in gardens and around buildings and sports fields.
• Ideal for drainage and infiltration of rainwater in houses with thatched roofs.
• Prevents flooding in rural areas.
• Local rainwater buffering and drainage. Supplements groundwater in a natural way.
• Prevents soil dehydration. Trees and plants enjoy rainwater for longer.

Durability
Hydrorock® is made of stone wool, a 100% natural material. It remains underground for decades in an optimum condition. Hydrorock® withstands erosion from plant and tree roots and continues to work well for years. The cotton-based filter cloth membrane does not get mouldy or rot. It has a high breaking strength and resists natural substances in the soil.

Vertical Or Horizontal Installation
Hydrorock® blocks have a fine, unidirectional fibre structure. A horizontal fibre direction promotes drainage while a vertical fibre direction promotes infiltration. For drainage of surface and rainwater, the blocks should be positioned horizontally. For buffering and infiltration of rainwater, the blocks should be positioned vertically.

Easy Installation
Hydrorock® is available in narrow blocks of various sizes. The enormous buffering capacity and dimensions limit the amount of digging required. Depending on the application, blocks are placed one after the other or beside one another to form the required buffer, drainage or infiltration system. They are suitable for any required capacity and situation. Digging narrow trenches is sufficient and limits the cost of removing surplus soil providing flexibility and simplicity.
