KLB offset blocks

Blocks for creating level layers

KLB offset blocks are placed on the uneven cover panel into a thick-bed joint of normal mortar ≥ MG IIa. After appropriate horizontal orientation they form a level layer, on which, once the mortar has hardened, the subsequent flat elements, flat blocks or flat stones can be mortared using thin-bed mortar. The KLB offset blocks are butted together narrowly and the open face side grooves are filled with mortar.

KLB offset blocks are produced in SFK 20 - RDK 2.0 or heat insulated in SFK 4 - RDK 0.7. The blocks are manufactured in accordance with DIN V 18152-100.
