Stone retention walls from solid materials are used for passive and low-energy buildings, which ensure perfect heat – insulating properties. Stone facades are a durable and maintenance-free solution for all facade surfaces. The thickness of the stone itself is 15 cm, the complete retention wall to 20 cm. With the lining it is necessary to calculate it already in the project, which must include the enlarged foundation strips. Otherwise there can be used steel extension anchors, but this solution is relatively economically demanding. Selected materials are also available in a thin variant for contact bonding, including corner pieces. Rustic materials can, of course, also be used in the construction of fences, garden walls, etc. We also supply stones only as material for k  self-assembly. S due to the location and the great mass of stone it is necessary to pay attention  to the structural stability of the works, therefore& nbsp; we recommend using k  a professional assembly company with provable  experience.
