Bufferblock is the creator and developer of the innovative solution for stormwater drainage and buffering in the urban area: the Bufferblock. The function of this concrete element is similar to that of infiltration crates, but because of the high strength a much thinner top layer is needed. This results in a less deep installation depth, higher buffering capacities and a more cost-effective solution. Stormwater enters trough a permeable pavement/road or through a street gully in the cavities of the Bufferblocks, after which the water infiltrates into the soil or is redirected. The Bufferblocks have a water storage capacity of 250 to 500 liters per square meter and can resist heavy traffic loads. The Bufferblocks are also easy to inspect and clean with commonly used inspection equipment.
