TWINSTAR PRECAST

IF YOU CAN DREAM IT, WE CAN MAKE IT

Your go-to problem solver for those difficult, once-off jobs that make civil engineering & construction challenging

  • THE GAP AND HOW WE DIFFERENTIATE OURSELVES

    With 26 Years of experience in the Precast Industry, owner-operator Annemerie Coetzee, realized that there is a gap in the Precast concrete market for custom-made products and once-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 disrupts any normal well-oiled production line, and in addition requires additional skills and supervision.

    This makes custom-made, one-off product manufacture an unprofitable business for mainstream, high volume operations. On the other side not all building contractors have the necessary expertise, manpower and facilities to manufacture such products on site.

  • OUR HISTORY

    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 just won’t work.

    TWINSTAR PRECAST strives to be the problem solver, and are solution driven in all aspects of precast concrete. With products ranging in weight from 2 kgs up to 6 tons, they are capable of solving almost all precast problems and turning nightmare requirements into a quick and affordable solution.

    To date it is the only company in SA specializing only in custom-made and one-off precast concrete products, only keeping a few fast-moving products in stock which are standard spec in tenders and drawings. Companies who previously made them have either stopped or have closed down.

  • OUR ORGANIZATION

    TWINSTAR PRECAST’s manufacturing facility is situated in Olifantsfontein, Gauteng, but deliver anywhere in South Africa.

    Our 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 of slabs during installation.

  • OUR RELATIONSHIP WITH THE INDUSTRY

    It has a unique relationship with the mainstream Precast Concrete companies who pass on referrals, and use TWINSTAR to supply certain non-standard products in order to keep their clients happy. As far as possible it uses small local suppliers rather than large corporate companies, and SMME’s for transporting our products. Marketing is mostly online, but direct contact is made with specifying engineers to make them aware that the need for custom-made products can be met.

  • OUR ACHIEVEMENTS

    In 2016 TWINSTAR PRECAST assisted a client in successfully closing old mineshafts in Gauteng which have previously been closed on numerous occasions but could not withstand vandalism, and were rife with illegal mining activities. These 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 also reduces the safety risk of open manholes as well as the financial implication this has on Councils and developers. The company manufactures manhole lids and frames as well as storm water gratings. These components can be bought as a loose item, or casted into the required precast concrete slabs.
    In 2012 Annemerie Coetzee was part of the team who received the CMA award for excellence in innovation for her contribution in the design and development of the bomb proof ATM enclosure.
