In many cities the existing drainage system is not designed for the increase of prolonged and severe rain showers resulting in flooding of streets. With the Hydrorock solution excess water is buffered quickly and easily under the existing infrastructure and infiltrated into the soil. Thus the chance of inconvenience is reduced strongly and it contributes to the improvement of the soil and the groundwater level. Simple solution for existing infrastructure The Municipality of Amersfoort experienced much inconvenience from puddles in a parking area in the city centre of Amersfoort. In times of heavy rains the capacity of the drainage system is insufficient and subsequently the parking area becomes flooded. With the installation of Hydrorock buffers the excess water will be absorbed quickly from now on. The infiltration blocks which can buffer 95% of their volume of water, then gradually release the water to the soil. Now there are no more puddles on the parking lot. The system may be used in existing situations effectively, as the groundwork remains limited in comparison with alternative solutions. Ecologically responsible For the buffering and infiltration Hydrorock uses rock wool, a 100% natural material. It is exceptionally suitable for application in urban environments with problematic water drainage. It offers a sustainable and ecologically responsible solution for the buffering and infiltration of rainwater in the urban environment.
