The Bufferblock system is modular and flexible in possibilties to connect to other sewer systems. As a result, the system can be used in various situations. Below is an overview of the possible applications of the Bufferblock system.

As an infiltration system, rainwater is absorbed through a water-permeable top layer in the hollow spaces of the blocks, after which the water infiltrates into the soil. Due to the high strength of the blocks, the required ground cover is minimal. For an average traffic load a total ground coverage of only 23 cm is required.

As a result, a lot of water can be stored in the first 68 cm below the street level. The Bufferblocks have a capacity of 266L/m². Including the waterstorage capacity of the top layer, it is therefore possible to store approx. 350L/m² in just 68 cm depth.

In combination with a geotextile with a very open structure (O90> 300 μm), the Bufferblock ensures that the Bufferblock system remains sufficiently water-permeable throughout its lifespan.

If it is not desirable or possible to have rainwater infiltrate into the soil, the Bufferblocks can be placed on a waterproof membrane with a protective cloth, after which the stored rainwater is drained away.

It is also possible to reuse the stored water. For this purpose, the Bufferblocks are placed on a watertight membrane with a protective cloth, where a inspection well with a pump is connected to the Bufferblock system.

In case it is not desirable or possible to conduct water through a water-permeable top layer into the Bufferblock system, it is possible to connect a street gully directly to the Bufferblock system.

By applying a street gully with filter and sand trap, pollution is prevented from entering the Bufferblock system.

Another possibility is to connect a street gully without a filter through a separate filter and sand trap on the Bufferblock system.
