APPLICATION METHOD

The brick «Block» 25Χ25Χ12 is appropriate for use in one shell protected masonry. It is intended to be used in combination with mortar, creating masonry shells 25 cm width. When the cutting of the piece is needed, then it must be done with the usage of an angle diamond grinder.

For the usual height of the masonry walls in buildings which are constructed in Greece and in the foreign countries (2,40-2,80m) the making of a concrete tie beam (chainage) is not necessary.

The clay unit itself is not intended to be used in masonry buildings (stressed), although due to its compressive strength it is appropriate for use together with other units. The clay masonry unit is not a facing brick.
