NO SOUR GRAPES FOR SIKA AT GRAHAM BECK WINE ESTATE

Graham
Beck Wine Estate is situated in the breathtaking Breede River Valley near the town
of Robertson. 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 (Pty) Ltd called on
Sika’s expert advice to find a solution to the cracks.  Anthony Webster, technical
sales consultant – Contractors, recommended Sikadur®-52 ZA, 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.  He then advised
a 3 to 4 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 (Pty) Ltd 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 6mm 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.
