PRECAST FOR LIFE TROPHY
WINNER
The Waterfront Knysna Quays,
Western Cape
A trip along the Garden Route is not
complete without a visit to the famous
Knysna Waterfront. Arguably one of
the most popular leisure and shopping
destinations in the region, boasting a
superior marina, the waterfront offer
various restaurants, boutiques and other
speciality shops.
This project was completed in
October 1998. Signature Fan cobbles line
the marina and offer an overflow area
for the restaurants. After 17 years these
cobbles are still beautiful and their
installation pristine.
Judges’ comments
Has withstood the harsh climatic condi-

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.
• The Castle Botton Kerb eliminates
air pockets in the screed which could
create weaknesses under the kerb after
installation.
Judges’ comments
An effective and cost-effective alternative to
satisfy extreme technical demands, made this
an impressive solution.
