The construction of the China Cash and Carry sales outlet at Crown Mines, Johannesburg presented architects with an interesting challenge – to develop a centre that is functional to both retail and wholesale shoppers.
A young entrepreneur who “fell in love with construction” is today running her own busy construction company handling a multimillion rand contract to pave township roads in the North West Province – and sees the prospect of more such contracts on the way.
The Concrete Manufacturers Association (CMA) has introduced a new paving manual – A Step-by-Step Guide to Perfect Paving – to support skills development and boost employment opportunities in this field. The manual has been developed primarily to be used by people who are unemployed and want to learn how to lay concrete block paving as a useful income-producing skill. However, it is sufficiently informative and technical to be of use as refresher material or a ‘How To’ reference for established contractors, big and small. The CMA is also offering the manual to training and technical institutions to be incorporated into construction-related course material.
SANS 1058 - 2010, the new SABS (South African Bureau of Standards) standard for concrete block pavers (CBP), has been amended. The new standard was announced in March 2010 and was officially introduced at the beginning of September 2011, giving manufacturers an 18-month window to alter their mix designs and production processes to achieve compliance with the new standard. However, the Concrete Manufacturers Association (CMA) has initiated an amendment to the new standard which lowers the performance criteria of the standard – albeit only marginally. In addition, the two strength ratings within the standard have been renamed for greater clarity.
Technicrete’s Trojan concrete pavers were chosen to surface the parking areas and traffic thoroughfares at Fancourt Office Park, a complex of 18 office buildings and one of the latest developments in the still growing North Riding node of Johannesburg.
Revelstone, a leading manufacturer of cast stone products, used Pareflo 20 silicone water repellent, supplied by Chryso SA, for the paving at the pioneering Nedbank Ridgeside development in Umhlanga Ridge in KwaZulu-Natal.

As the home base for the England squad during the 2010 FIFA World Cup™, the Royal Bafokeng sports campus presented an opportunity to showcase South African concrete paving and roofing products to an international market. Located not far from Sun City in North West Province, the complex incorporates a five-star hotel and facilities for a range of sports activities, including soccer, rugby and tennis, plus a tennis clinic.
THE ‘lows and highs’ factor is a common problem when laying interlocking concrete paving. It happens when inferior quality pavers of irregular depth don’t fit together easily. The result is an uneven surface and a bumpy ride. But that was no problem for the contractor laying over 2 000m² of Technicrete’s Double Zig-Zag paving blocks at the new Grey Owl shopping centre in Midrand, Gauteng.
Paving producers that hold the SABS (South African Bureau of Standards) mark for concrete block pavers (CBP) tested and approved to SANS 1058, have 12 months in which to comply with the revised standard, SANS 1058 2010, which was published officially by the SABS in March.
One of the most extensive paving projects in the North West Province www.nwpg.gov.za – at the Mafikeng Industrial Development Zone (MIDZ), adjoining Mafikeng Airport – was completed and handed over at the end of last year. Strategically located close to a major rail link and with an internationally rated airport on its doorstep, the MIDZ is intended to position Mafikeng
An independent survey conducted in Gauteng on behalf of the Concrete Manufacturers Association (CMA) last year shows that concrete block paving (CBP) is, in most instances, a more cost-effective surfacing option for driveways, car parks, residential streets and township roads than premix asphalt paving (PAP). The survey also found CBP to be more cost-effective for light and heavy duty industrial yards, bus terminals and through-roads in urban areas. The results of the survey have been published by the CMA in an updated leaflet, previously published in 2007.
Infraset Building and Landscaping Products recently saw its Uni-Ecolok permeable interlocking concrete pavers installed for the first time on a suburban property in eastern Johannesburg where the former house has been converted to offices.
