Never Been so Easy

Our Blocks

section through a geopolymer concrete Polyblock, showing the insulation


More than 80% of the block volume consists of insulation. The insulation core provides protection against coldness and heating. The shell of the block accounts for 20% (by volume) and is made of sustainable geopolymer concrete, which takes over the statics. With 1m³ concrete 20m² of wall surface can be build.

Special Block

For the installation of the sanitation pipes there is an additional block. This block corresponds to the dimensions of the other Polyblocks. There are openings on the sides, which allow the installation of pipe systems for fresh and waste water. Electric power cables can be lead through every Polyblock (vertically) and special blocks (horizontally)

The Material

Sustainable Geopolymer Concrete

Polyblocks are made from environmentally friendly geopolymer concrete which consists 90% filler of naturally occurring sands and 10% binder.​ The sands are freely available raw materials​ that include secondary raw materials from mining or agricultural industries.

Material Benefits

Compared to conventional concrete our concrete has lots of beneficial features when it comes to water consumption, carbon emissions, compressive strength and density.

Endless Possibilities

With a total of 5 blocks all straight wall configurations can be easily built in any geometry. A range of other components, like window and door intels make our system complete allowing the construction of complex modular buildings by hand.
