Custom-made and one-off precast concrete products

Twinstar Precast is the industry-leading expert in SA for the design, manufacture, delivery, and placement of custom-made and one-off precast concrete products for construction companies working on projects in the public and private sector, and civil engineering contractors.

With 26 years of experience in the precast industry, owner-operator Annemerie Coetzee realized that there was a gap in the precast concrete market for custom-made products and one-off items. In the concrete pipe and manhole market, for example, the emphasis is on high volumes, and the effort and time required to design and build once-off moulds for non-standard products disrupt any normal well-oiled production line, and also requires additional skills and supervision. This makes custom-made, one-off product manufacture an unprofitable business for mainstream, high volume operations. However, not all building contractors have the necessary expertise, manpower and facilities to manufacture such products on-site.

Twinstar Precast was founded in 2014 with the express aim of assisting specifying civil engineers and civil engineering contractors with complicated sites and situations where currently available precast concrete products would not work. Twinstar Precast strives to be a problem solver and is solution-driven in all aspects of precast concrete. With products ranging in weight from 2kg up to 6 tons, the company is capable of solving almost all precast problems and turning the nightmare requirements into a quick and affordable solution. To date, it is the only company in South Africa specialising in custom-made and one-off precast concrete products, only keeping a few fast-moving products in stock that are standard spec for tenders and drawings.

Twinstar Precast has a unique relationship with mainstream precast concrete companies that pass on referrals and use Twinstar to supply certain non-standard products to keep their clients happy. As far as possible, Twinstar Precast uses small local suppliers and SMMEs, rather than large corporate companies, to transport its products. Marketing is done mostly online, but direct contact is made with specifying engineers to make them aware that their need for custom-made products can be met.

Achievements include manufacturing of polymer products

In 2016, Twinstar Precast assisted a client in successfully closing old mineshafts in Gauteng which were previously closed but could not withstand vandalism, and were rife with illegal mining activities. Twinstar Precast’s mineshaft slabs are still intact, and no illegal activity has been reported since.

In 2018, Twinstar Precast started with the in-house manufacturing of polymer products. The risk of theft of products with steel and cast iron components increases daily. These polymer products have no metal components and reduce the safety risk of open manholes as well as the financial implication this has on councils and developers. The company manufactures manhole covers and frames as well as stormwater gratings. These components can be bought as a loose item, or cast into the required precast concrete slabs.

In 2012, Annemerie Coetzee was part of the team which received the CMA Award for Excellence in Innovation for her contribution in the design and development of bombproof ATM enclosure.
Twinstar Precast’s manufacturing facility is situated in Olifantsfontein, Gauteng, but deliver anywhere in South Africa. Its crane mounted trucks can offload the product directly on site. The company also offers a service where the crane-mounted trucks can assist with placing slabs during installation.
