HOLLOW CONCRETE BLOCKS

The Betoneks hollow concrete blocks are suitable for laying foundations, bearing and partition walls. The blocks can also be used in refractory walls. The hollow concrete blocks must be installed so that their cavities are over one another. Mortar must be applied onto all edges of the blocks. Vertical cavities should be concreted at their full extent next to the apertures and at wall intersection spots. Prior to concreting make sure that the mortar in the joints has had at least 24 hours to harden.
