Invented by Capetonians, Andre Esterhuizen and Riedewaan Jacobs, Stumbelbloc is the perfect innovation to greener building. Concrete bricks shaped like lego-blocks fit into each other in a compact stacking method. Each block has two cavities which allows it to be filled with polystyrene chips known as regrind. This then acts as insulation.
This unique building method allows for building of houses without the use of electricity, which saves costs all round.
This is a great way of recycling polystyrene waste which would otherwise cause environmental damage if not disposed of in the correct manner. This method of insulation could revolutionize construction methods of the future.
With Stumbelbloc the house is built in its entirety from base to roof height with the cavities only then filled with the polystyrene regrind. A special sealing block can be made with the same Stumbelbloc mould which is then placed on top.
Only the cavities that are holding the electric wiring are not filled with polystyrene – these cavities are filled with perlite insulation which is fireproof.
Instead of using conventional cement mortar, all Stumbelbloc variants are joined together using Blockgrip (a thin-bed product similar to mortar). Blockgrip sets in three hours, and is applied only to the bottom of each block by dipping their bases into the mix. This makes the construction process significantly quicker and cheaper than conventional methods.
No lintels are required for standard openings such as doors and windows when using Stumbelbloc. Instead, a lintel-like equivalent can be made by adding reinforced steel rods and filling the block cavities with concrete.
