WATER RETENTION

RAINWATER
HARVESTING

Drainblock combines rainwater harvesting, water retention and infiltration into one. The collected water is available for re-use or groundwater recharge.

UNDERGROUND WATER RESERVOIR

Drainblock can retain almost 100% of its volume in water and offers large scale underground water retention with no maintenance. Water collected from roofs, parking areas or roads is immediately absorbed by Drainblock. Underground water reservoirs of any size and shape are easily created, making Drainblock the perfect solution for urban areas.

INFILTRATION

GROUNDWATER
RECHARGE

Drainblock recharges the groundwater through natural infiltration. As the water is filtered Drainblock gives clean water back to the environment. Drainblock can help creating artificial aquifers.

INFILTRATION

FLOOD MANAGEMENT

Drainblock stores water at a very high speed. In many locations Drainblock is used to prevent floods or reduce the impact of flash floods.

WATER RETENTION
& STORAGE

Drainblock holds water against gravity and can be perfectly used in hilly regions to minimise run-off and reduce peak flows.

DRAINAGE

Drainblock is used as urban stormwater drainage system. Drainblock drainage systems hold and retain water. When Drainblock is saturated it functions as a drain with delayed discharge.

WATER TREATMENT

MECHANICAL
FILTRATION

Drainblock has a great permeability making it the perfect mechanical water filter. Before channeling the water to a Drainblock underground water reservoir suspended solids will be filtered out by our Drainblock filter thereby minimising maintenance to cleaning the filter only.

BIOLOGICAL
TREATMENT

Drainblock's Cleanblock is inorganic and has great permeability providing a superior environment for bacteria colonisation. Our Cleanblock solution is widely used to treat contaminated open water streams and effluent from septic tanks.

LAND SCAPING

GREEN ROOF

Drainblock is the perfect material for low maintenance, sustainable green roofs. With almost 100% water retention capacity and a very low weight it can be applied at almost all rooftops.

GARDENS

Drainblock is a superior substrate that provides an underground water buffer for plants and trees in gardens. Drainblock is the landscape architects favourite and best friend in creating a beautiful lush green environment.

GREEN
BELTS

Drainblock provides the combination of storing rainwater from roads and buildings, and makes it available for the greenbelt alongside these roads.
