South African Paving Manufacturers
Choose your paving manufacturer carefully.
There is only one Standard for the manufacture of paving; (SANS 1058). There are two bodies that can test the compliance with SANS 1058 namely the South African Burau of Standards (SABS) and the Concrete Manufacturers Association Certification Services (CMACS). The testing authority is irrelevant, what is important is that the manufacturer should comply with the South African National Standard (SANS) ad that it has a certificate from one of these bodies to prove it.
It takes a lot of money and effort to comply with the National Standard.
Unfortunately there are unscrupulous manufacturers who do not comply with the national standard. They do all kinds of fraudulent things to trick consumers into thinking that they do. Some proudly display the CMA (Concrete Manufacturers Association) logo on their website and material and claim that their products are CMA approved. There is a distinct difference between the CMA and CMACS. They are two separate entities all together.
Some present their CMA membership certificate as proof of their “compliance” with SANS. This is fraudulent. They should present a CMACS certificate of compliance.

If the company in question is not on this list, they are not SANS approved.
When it comes to simulated stone, there are even more irregularities because there is no National Standard for the manufacture of Wet Cast Concrete flagstones, pavers and cobbles.
The best thing to do in this regard is simply to deal with a reputable company. There are reasons why one manufacturer may be more expensive than the next. The good manufacturers have a quality management system and reputation to uphold. You can rest assured that they will deliver on time and that their products have been manufactured with material fit to make concrete. Furthermore, you can rest assured that these manufacturers used reliable cement like PPC, Afrisam, Sephaku etc.
