Hollow blocks and foundation blocks combine high stability and solidity with low weight. Fixed joints are produced, which satisfy high structural standards.
Particular projects require individual solutions. Do you need curbs with vertical and horizontal displacement protection, large format systems with false joints or contours in the underside of the block?
Wall and soil retention blocks can be used for multifunctional purposes and are of central importance both in private and public spaces as design and functional elements.
