Holcim offers Betomat, a precast articulated concrete block mat, as a defence solution to the erosion of embankments and bottoms of waterways, due to high winds, waves or currents. Ultimately, the open Betomats can blend in completely with the natural environment. Betomats come in various sizes and weights of interlocking concrete block mats with versatile application possibilities. They can be installed both above and below water to strengthen and protect banks, while increasing the integrity and stability of the construction.

The application of the Betomat in engineering projects makes it possible for construction teams to easily install secure bank defences quickly. The Betomat can be laid underwater and extended without disturbing the upper embankment. The geotextile, which is inseperably linked to the concrete blocks, prevents the soil from washing out. Thanks to its flexibility, Betomat can even compensate for minor subsidence of the soil.
