Fixing the insulation material to the Keraterm walls. The insulation dowels are easy to fix to the walls of the Keraterm block. In this video you will see for yourself:

Three important rules must be taken into account when fixing KERATERM masonry. Very often customers ask how to fix dowels correctly in KERATERM blocks and which dowels to use for KERATERM blocks. This video explains exactly.

• When drilling holes for fasteners, the drilling machine must be used in drilling mode only (no percussion-drilling mode). Otherwise, the edges of the bore hole may be chipped out in the internal partitions of the block and the dowels will not be able to lock firmly in the bore hole. Of course, a sharp drill designed for masonry must be used;
• The dowel cores must be screwable, or in practice they must have screws corresponding to the dowels, and they must also be screwed in with a screwdriver rather than driven in with a hammer;
• For reinforcement in KRATERM masonry, dowels suitable for perforated bricks and/or perforated ceramic blocks must be selected.

There are two ways of creating underground ducts for cables, water pipes, heating, etc. in KERATERM blockwork.

Firstly, by using a diamond cutter, which is designed for such work.

The second method, or “economic” method, when there is no masonry cutter, is to make the channels with a hand-held angle grinder using a diamond segmental cutting wheel.

The following procedure is to be followed: using a masonry router or angle grinder, and adjusting the required depth of the channel, saw the boundaries of the next channel, forming two cut lines, then accurately chisel out the middle part of the channel. In the forging process, hand tools – hammer and chisel – are preferred.
