Stumbelbloc is fast becoming the farmer’s first choice of do-it-yourself construction because it is economical and easy-to-use, and the durability and versatility of structures impress.
“The system’s versatility means that farmers are able to build anything from houses and swimming pools to warehouses and all the way down to septic tanks and French drains,” says André Esterhuizen, inventor of Stumbelbloc.
Farmers can make blocks for as little as R4 ($0.51) if they have the right sand or gravel in dry river beds says Esterhuizen. This means that they can construct walls for less han R98/m² ($12.49/m²).
“The plastic moulds with which you make the blocks are very unique in the sense that you can start a small do-it yourself factory with as little as 34 moulds or grow to any limit, depending on the size of the project,” he adds. “34 blocks are produced with one bag of cement; three wheelbarrows of sand and two wheelbarrows of 13mm stone. This mixture produces 5.5 megapascal (MPA) blocks (3.5 MPA is required for single storey buildings up to 3.3 metres high with a gable of 5.2 metres high.) You can also determine the strength of the blocks by simply changing the cement percentage.”
“The tendency for farmers to finance moulds and train workers to build their own houses is growing fast,” says Esterhuizen. “A typical example of how Stumbelbloc has been used as an upliftment and employment tool is in Marydale in South Africa’s Northern Cape province. Here Pastor Hennie Mare convinced farmers to invest in the upliftment of the town’s 2,500 people – 85% of whom are unemployed. Not only did the farmers buy the moulds through the church to start a brick factory, they are also buying the blocks, training and paying the workers to do construction, which is creating employment for the benefit of all.”
“While this particular project was launched as a charity initiative, it is fast becoming a self-sustaining business that benefits the whole community, and similar towns are watching them closely and investigating the opportunity.”
Pastor Mare says: “The demand for the blocks is so great at the moment that we are turning away orders because the factory cannot meet the demand. We have also had to change our non-profit organisation status to a not-for-profit company, and we plan to use the profits for further upliftment.”
