The Hydrorock® D220 is a 120 x 40 x 50cm (LxWxH) drainage block with an absorption capacity of 220 liters. Hydrorock® technology is based on infiltration. Once placed they can absorb the water, they then buffer by allowing drainage through the blocks, the blocks will repel the water to the bottom and sides dispersing it underground slowly to not create hollow cavities.
Distributor through drainage, linewater drainage of rainwater around hardened surfaces, under (gravel) trails and in gardens (connecting to the sewer is not possible and also unnecessary). The infiltration blocks can be dug into locations that easily flood, as stand alone blocks or in a sequence of multiple blocks. They are also ideal for drainage and infiltration of rainwater in houses with thatched roofs.
The drainage blocks are dug in at approximately 20 cm below ground level without finishings. The blocks are placed rear to rear or side by side, thus forming the desired buffer and drainage system. Always fitting to any capacity and situation. Digging of narrow trenches is sufficient and costs for the discharge of excess soil are limited. In short: flexible and simple.
