The Betomat Porous is a precast articulated concrete block mat which consists of concrete blocks with an open structure and are tightly secured to a geotextile. The amount of open spaces (approx. 25%) in and between the concrete blocks means that the banks can have a complete natural look as the Betomat becomes one with the environment. To achieve a natural appearance, the tiles can be filled with soil and the slope sown with grass seed creating a grass-green yet concrete-strong result. In fact, the vegetation even contributes to the stability of the slope.

This makes this type of Betomat ideally suited for use in recreational areas and other places where a natural appearance of
embankments is desired.
