Dense concrete blocks
Concrete blocks are made as standard from C12/15 concrete suitably vibrated. We also produce them in higher strength C16/20 and C20/25 versions. They are used to build external load-bearing and curtain walls, internal load-bearing walls, foundations, basement walls, slotted walls and retaining walls. They can also be used to make fences and openwork walls. These are elements with a cuboid shape, which can be used in widths of 38 cm and 24 cm.
Build blocks using cement or cement-lime mortar. Cement mortar is used for walls in contact with the ground. The walls are laid with full horizontal and vertical joints. When building foundation walls in buildings without a basement, the last layer of the wall should be a reinforced concrete ring made with the KNW system mould. Before installing vertical wall insulation below ground level, each wall is levelled with a thin layer of cement plaster in accordance with good building practice.
