Lammi hollow concrete blocks

The vertical dimension of the hollow concrete blocks is diamond-ground to the exact size. Thanks to this, even tall structures are quick and easy to assemble. The work is also made easier by the use of end and corner blocks. In hollow concrete block structures, the concrete cover to the reinforcement is always thick enough. Reinforced hollow concrete blocks create a solid, airtight and robust structure that provides good sound insulation, is non-combustible and does not rot. Before casting, the necessary service installations can be installed inside the hollow concrete block structure. This eliminates the need for labour-intensive casting-in work in the wall.
