INNOVATION TROPHY WINNER Castle Bottom Kerb The Castle Bottom Kerb is patented (SA2012/09544), clear evidence of innovation. Prerequisites for a patent are that an inven- tion should be novel and hold clear advan- tages over existing and similar products. Advantages of Castle Bottom Kerbs: • Cavities provide grip for installers making for much easier handling. • The cavities make the kerb much easier and quicker to install. In instances where unlevelled screed surfaces force installers to lift fill and relay conventional kerbs, Castle Bottom Kerbs are much easier to manoeuvre into place. • Because the Castle Bottom Kerb has more load points it sinks into the screed, providing much better adhesion in all directions. tion winners were Concrete Units and Aveng Infraset. Concrete Units won the award for manufacturing precast concrete rock print panels for the Mouille Point Sea wall Project in Cape Town and Aveng Infraset for providing non-standard portal culverts for the Tweefon- tein Optimisation project in Mphumalanga. • SmartStone – the Precast for Life trophy for supplying Fan Cobble paving blocks for the Waterfront at Knysna Quays project in Knysna. Apart from the Aesthetic Residential category all other categories posted two commenda- tion winners each. The Aesthetic Commercial commenda- tion winners were: SmartStone Midrand and Bosun, the former for supplying pavers and coping for the Thaba Moshate Hotel Casino and Convention resort in Limpopo, and the latter for providing drycast paving blocks for the courtyard of BMW’s head office refurbish- ment project in Midrand. C.E.L. Paving Products and Hydraform each won a Community Upliftment commen- dation.
