MH150

The corners of the hollow concrete block structure are easy to construct using the pre-made corner block. The blocks are designed for 2M modular layouts, based on 200 mm increments. The corner blocks have recesses for horizontal reinforcement and interlocking profiles that engage with the basic blocks.

Corner blocks are laid so that the block in every other course faces the opposite direction to the one in the course below. This creates a 200 mm overlap in the wall. The corner blocks can easily withstand the casting pressure from the concrete infill. As the structure itself is not secured to the adjacent blocks, the hollow concrete block structure must still always be supported during casting, at least at the corners and end blocks.

The corner blocks are sold in pairs (1 pair = 1 left-hand and 1 right-hand corner block).

We offer ready-made end blocks for window and door openings, as well as gable wall structures. Using end blocks eliminates the need to cast the frames around the openings separately during the casting process. This speeds up the work considerably and reduces the workload.

With standard block stacking, the hollow concrete blocks always have a 200 mm overlap. For this reason, we pack both long (600 mm) and short (400 mm) end blocks onto the same product pallet. In this way, the end blocks do not need to be cut to size on site in order to achieve the overlap.

The end blocks are sold in pairs (1 pair = 1 long and 1 short end block).

The Lammi KMH150 curved hollow concrete block is suitable, for example, for bay windows, silos, swimming pool structures, retaining walls and curved foundations. A curved block can be used to create curved structures with a diameter of 3–7 metres. To construct larger curved structures, straight MH150 hollow concrete blocks are also required. Stackable, castable hollow concrete blocks are easy to handle, and once filled with concrete, the blocks form an exceptionally strong finished structure.
