When the world-class Graham Beck Wine Estate needed an additional bottling and storage area, CSV Construction turned to Sika’s renowned Sika PurCem flooring system to give the new building an attractive and clean finish.
Graham Beck Wine Estate, situated in the breathtaking Breede River Valley near the town of Robertson, is an easy drive along the scenic Route 62 from Cape Town. Graham Beck’s world class wines, produced in harmony with nature, are testament to his passion for restoring and conserving the environment.
With the estate’s constant growth, an additional bottling and storage area was required. The client specs required that the floor in this new building was to withstand low to heavy traffic; as well as have an attractive and clean finish. For this, CSV Construction specified Sika’s renowned Sika PurCem flooring system.
The building of these additional requirements started in November 2018. Shortly after completion of the construction, severe settlement cracking was observed in the concrete floors, which demanded urgent attention.
Epoxy Flooring Systems called on Sika’s expert advice to find a solution to the cracks. Anthony Webster, technical sales consultant – contractors, recommended Sikadur-52 ZA. This is a two-part, low-viscosity, injection-liquid based on high strength epoxy resins. To start the repairs, Sikadur-52 ZA was used to fill and seal the cracks in the concrete floors on which the PurCem systems needed to be applied on. Anthony then advised a three to four month wait, to ensure complete sealing of the existing cracks, and to check no further cracking occurred. After first priming the concrete floor substrate with Sikafloor-161, a two-part, low-viscosity epoxy resin; Epoxy Flooring Systems applied the final PurCem floor coating.
Sikafloor-21N PurCem is a multi-component, medium to high strength coloured polyurethane modified, cement and aggregate screed with self-smoothing properties. It was selected for a smooth, flat and decorative wearing surface, with a medium slip resistance for light traffic areas. It was applied at a 4 mm thickness on the low to medium traffic areas. For the medium to high loading and high traffic areas, which require a more durable floor coating, Sikafloor-20N PurCem was used. This product, applied at 6 mm thickness on the wet floor areas, has a textured aggregate surface providing the medium to heavy profile slip resistance.
Sikaflex Pro-3 i-Cure, an elastic joint sealant, was used to seal all the connection joints where the Sikafloor -20N PurCem and Sikafloor -21N PurCem flooring systems had been applied.
As the original floor was in an extremely bad condition, the main concern was it would crack through the new flooring – so the correct and efficient repair was the primary challenge of this project.
