A collaboration between the Council for Scientific and Industrial Research (CSIR) and SMMEs is breaking new ground in addressing South Africa\u2019s housing crisis\u2014quite literally. Through a partnership with USIT and Keybricks, the team has developed an environmentally friendly, low-cost RDP house constructed using a unique, Lego-like \u201cKeybrick\u201d.<\/p>\n

Speaking to Radio Islam International<\/a>, CSIR’s Aubrey Muswena explained, \u201cThe house is being prototyped to test if the block\u2014and by extension, the house\u2014is fit for purpose. These bricks reduce virgin material input, and no cement is needed between layers.\u201d Made from 70% recycled material, including glass waste and construction rubble, these bricks are pressure-formed, significantly reducing water usage and cement content.<\/p>\n

Unlike conventional bricks, the Keybricks interlock tightly, ensuring durability even under force. Muswena recounted an incident where a worker attempted to dislodge a brick by kicking a wall. \u201cHe couldn\u2019t move a single brick. With the roof on, the vertical pressure just locked everything into place,\u201d he noted.<\/p>\n

This innovation not only targets the housing backlog but also promotes job creation. Glass bottles collected across KwaZulu-Natal, often stored in bulk bags, are not recycled as assumed. \u201cThere\u2019s a misconception that this glass is being reused. It isn\u2019t. But with our project, it will be,\u201d Muswena explained.<\/p>\n

Moreover, the system requires minimal skill to erect. \u201cWe put up an RDP house from foundation to roof in just seven days\u2014with one person doing it,\u201d he said. The bricks also feature internal cavities that allow concrete and rebar to be added for additional reinforcement, making them suitable for retaining walls and paving too.<\/p>\n

Still undergoing certification with Agr\u00e9ment South Africa, the Keybrick holds promise to reshape not only how RDP houses are built but also who builds them\u2014bringing green innovation and economic potential to communities that need it most.<\/p>\n

Further parts of the interview are expected to reveal how this initiative could transform waste management and informal employment across the country.<\/p>\n
