Concrete stormwater pipes have a long
lifespan but it is not infinite. Ageing infrastructure and pipe erosion and
corrosion are all factors that initiate the rehabilitation of stormwater piping
systems. Rocla, known for its
technical experience and product application analysis, was selected to design
and manufacture skew culverts for the Parktown Emergency Stormwater Project in
Johannesburg.
“An assessment of the relevant technical
and practical factors is key to the successful design of any element of
stormwater rehabilitation projects” said civil engineer, Muhammad Bodhania,
based at Rocla’s Roodepoort offices. “There were numerous technological
challenges presenting on the Parktown project, so meetings were held between
PGN Civils, the site engineer and ourselves in order to ascertain the most
appropriate design and product to be used for the successful installation of
the replacement skew culverts and bases” said Bodhania.
“The existing stormwater channel at
Parktown is a channel with a unique curvature. This is why Rocla had to design
and manufacture specialised skew culverts that could be installed into this
channel. We took the basic design of a standard Rocla culvert but manufactured
it at an angle to create a curvature that would fit properly into the existing
curved channel. We are proud to say that despite the challenges of the required
angle design we met the technical specifications completely”.
Rocla supplied 42 straight 2500 x 2500
SAR Culverts, 19 skew culverts and associated bases.
“We have worked with engineers at PGN
Civils and WBHO previously on specialised projects and they know of our
technical, design and manufacturing capabilities, hence Rocla being chosen to
assess and resolve the technological challenges of a very unique project”
concluded Bodhania.
The Parktown Emergency Stormwater
Rehabilitation Project started in February 2019 and is due for completion in
February 2020.
Rocla is part of the ISG which also
includes Technicrete.
