Nailing in KLB masonry

The nail remains the most used connection means if during the construction and finish phase a board needs to be attached or only the mason’s lacing cord is fastened. Later the nails are then used to hang pictures or other decorations.

KLB wall building materials are very easy to nail. The nails to be driven in do not have to be steel nails, because there is a fear that every attempt to drive in ends with a crooked nail, as is the case with some other building materials. The hammered-in nail then sits firmly in the KLB light-weight concrete and can only be removed using pliers, not fingers.

In some regions house facades are completely or partially covered with natural or artificial slate. Here it has been shown that these slate claddings can be directly nailed onto the KLB masonry. Extensive attempts at the roofer’s school in Mayen, Eifel, prove that for direct nailing into KLB square, galvanised nails have a high degree of resistance to being pulled out and the facade remains permanently stable.
