Waterkloof Quarry, an old 58-hectare landmark, situated on the border of Waterkloof Ridge and Monument Park near Pretoria is to be developed into an upmarket retirement estate known as the Waterkloof Marina Retirement Estate and is due to launch early in 2019.

Rocla was selected to manufacture and supply all the stormwater (spigot and socket) and interlocking pipes for the project.

Hannes Bezuidenhout, Estimator from Advance Projects said “This exciting development will consist of a mixed-use development which will offer a large selection of sectional title and full ownership retirement units and full support facilities such as a 24-hour frail care centre, medical centre, restaurants, recreation facilities – and I believe the Waterkloof Dam is still good for bass fishing!”.

“However, it was not without its challenges. The size of the pipes required for the development and the proximity of the pipe trenches to existing roads created some logistic issues in terms of excavation materials, pipe deliveries and existing traffic flow.

Rocla understood these issues and ensured that pipe deliveries were as we requested and that pipes were off-loaded as close to the excavated trenches as possible for ease of installation” Bezuidenhout commented.

“The timeframe for pipe delivery was a mere three months and it was Rocla’s capability to meet this timeframe, their competitive pricing and product availability that secured them the contract to supply over 614 assorted stormwater pipes. The whole project duration is six months said Bezuidenhout.

“Obviously when there are existing roads nearby or trench excavation working space is small, the delivery of large stormwater pipes can be problematic for contractors at site. At the Waterkloof Marina Retirement Estate project these factors needed to be addressed, particularly for the delivery of our large stormwater pipes, so that no major inconvenience or disruption to excavation scheduling occurred. I believe Rocla successfully met these specific challenges” said Brendon van Vuuren, Sales Consultant for Rocla.

Rocla’s spigot and socket stormwater pipes use the rolling rubber ring principal and no lubricant is required. Pipes within this category may be ordered as both stormwater culvert (SC) or stormwater and irrigation (SI) pipes. SI pipes are hydrostatically tested after manufacturing.

Rocla is one of South Africa’s leading manufacturer or precast concrete products for the infrastructure sector and is part of the IS Group of companies which includes Technicrete and Ocon Brick.
