Turf perforated brick for improved drainage of rainwater into the subsoil

摘要

The turf perforated brick for improved drainage of rainwater into the subsoil is in two parts. It consists of a grid frame and a plate. It can be laid on all ways (paths) and squares. The grid frame enables three-dimensional stability of the turf perforated bricks with respect to one another. Together with the covering plate, it ensures a non-compressible retention space for short-term water retention. The surface connection reduces compaction of the subsoil and increases, along with the retention space, the seepage rate of the rainwater.
