Stumbelbloc: Build for as little as 10 USD per m²


PROMOTIONAL FEATURE | 4 JUNE 2014

Is it conceivable that you can build a house in the cheapest possible way without air-conditioning in the middle of Africa?

Even more surreal is the fact that you insulate it with bio non-degradable polystyrene waste.

Can you believe that waste polystyrene chipped up and known as regrind can now insulate your house and change the R-Value from 2.5 to 8.0 by simply filling the walls with this inexpensive material, providing the building method allows it?

Stumbelbloc provides the answer

This innovative building method allows you to build a house without electricity in the middle of nowhere and it acts like a cold room.

"Yes that's hard to believe", says Andre Esterhuizen, CEO of Stumbelbloc. "You can produce the blocks and build a house entirely without electricity."

He also says that governments worldwide have a huge problem disposing of polystyrene waste. It is such a paradox that this waste material can revolutionise the thermal properties of construction methods.

You can buy the regrind very cheaply – creating an unbelievable effect on the insulation of a dwelling.

The polystyrene association of South Africa is looking desperately for ways to recycle and dispose of the mountains polystyrene created annually.

"It sounds like so much extra work to fill the walls of an entire house with polystyrene", says Esterhuizen, but the joy of Stumbelbloc is that you don't do it during construction. You complete the house to roof height and then simply fill the walls from the top!

The Stumbelbloc cavity remains open from roof to floor and the polystyrene falls down like water. A special closure block can be made with the same Stumbelbloc mould which is fitted on top of the polystyrene. Only the cavities that are holding the electric wiring are not filled with polystyrene – these cavities are filled with perlite insulation which is fireproof.

An entire house of 260m² can be core-filled by two labourers in one day; total cost of material: US$60. The cost per block would be only $0.70 if you made them yourself or $1.20 if purchased directly from an approved block producer. All in all, easier, quicker and cheaper than standard construction.

If this method is embraced, says Esterhuizen, it could be applied to various constructions such as chill rooms on farms, greenhouses, chicken batteries and hunting cabins.

Only the external wall of a low cost house needs to be constructed with Stumbelbloc as the system allows normal bricks to be tied into it.

These houses will be warm in winter and cool in summer.

Make your own blocks

Namibia – this system is very popular in Namibia.

Botswana – resettling in Botswana.

Kenya – widely used in Kenya (see Facebook link).

Thailand – see Facebook link.

Tanzania – schools, hospitals and houses being built in Moshi.

South Africa – Kommetjie.
