U-block

The U-block is the block that forms the top of the wall. It has an open channel on top, and consists of a hard surface layer on both sides with an insulating layer in the middle.

The blocks are stacked in a running bond and locked together with insulation plugs. No mortar, no glue and no formwork.



Three 12 mm rebars are placed in the channel before it is filled with concrete. This gives you a reinforced ring beam that ties the columns in the wall together.

Get a stronger wall by running the pipes through, with the U-block on top

The ring beam makes the structure self-supporting, and you can build up to 3 storeys.

How to build


1. Prepare the ground. Compact and pour a base slab, or build directly on firm, well-drained ground.

2. Lay the first course. Set the bottom course level. It is the starting point for the whole wall.

3. Stack and lock. Stack the blocks course by course in a running bond and lock them with plugs. Add the reinforcement.

4. Fill with concrete. Pour concrete into the cavities, only 25 litres per m².

5. Roof and finish. Fit the roof trusses, and render or paint the walls as you like.
