The Albanian coastline has been declining in recent years due to coastal erosion and uncontrolled...
Due to climate change, more and more heavy rainfalls will occur and many cities are now facing the problems of streets being flooded because of the stormwater. Our innovation gives these cities a cost-effective solution which provides high amount of stormwater storage in little space needed.
Developed by Bufferblock BV
The Bufferblock is a solution for stormwater drainage and buffering in the urban area. The function 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.
See more information about this level and the TRL and SRL levels.
The concrete Bufferblocks are designed to be placed underneath a permeable/porous street layer, but it is also possible to use closed pavement stones or asphalt on top when water is directed to the Bufferblocks via a street gully. During heavy rainfall the stormwater will go through the permeable top layer or via the street gullies inside of the Bufferblocks where the stormwater is stored and eventually infiltrates into the ground or is redirected to a sewer system. Because the stormwater is temporary stored inside of the Bufferblocks, the main sewer system will not get overloaded by a peak in water discharge due to the rainfall.
Limitations/conditions under which this innovation does not work or is less effective
Preferably the blocks are placed under roads where there are no cables and pipes directly underneath the surface. Bufferblock also provide solutions where the blocks and a cable compartment can be combined.
Added value
There are many types of stormwater drainage systems. The stormwater system which are mostly used nowadays are plastic infiltration crates and infiltration pipes. Our innovative is a solution which stores high amount of water in low height needed to place underneath the streets. Especially in cities with a high groundwater level like Rotterdam, the Bufferblock will be an effective solution. The Bufferblocks need less height underneath streets, because of the strength of this concrete product. Traffic loads from the street layer on top of the Bufferblocks can almost directly be carried by the Buffeblocks, whereas plastic infiltration crates need a ground coverage of at least half a meter to spread the traffic loads. Computer simulations and prototype testing have proven the required strength of the Bufferblocks to carry heavy traffic loads. Besides from having a functional edge to the competitors the Bufferblocks also have a financial edge. Because of the material used and the simple structure, the Bufferblocks are easy to produce and are cheaper than competing products.

The main components of the system have been tested separately, and an initial integration exercise has been conducted.
