PRECAST SOLUTIONS FOR STORMWATER AND SANITATION

Within this field, precast manufacturer Rocla and sister entity

Technicrete (both forming part of the IS Group) continue to field purposedesigned solutions for upgrade, mitigation and repair projects across South Africa.

Recent examples within the sanitation field include the supply of Rocla’s rolling joint spigot and socket pipes for flood damage repairs to the main sewer line along Queen Nandi Drive in Durban. In total, around 41.48 m of 1 350 mm diameter pipe was supplied from Rocla’s factory in Roodepoort, Gauteng.

Hazeldean Boulevard

Various integrated IS Group solutions have also been supplied recently for the Hazeldean Boulevard upgrade, which forms part of the Riverwalk Road Project near Pretoria East. Carried out by Kwa Mhlanga Construction, the project scope aims to reduce traffic congestion between the Blyde and Silver Lakes residential estates, in addition to improving stormwater infrastructure. Rocla supplied 1 564 interlocking joint pipes of varying sizes, while Technicrete delivered close to 7 km of Fig 7 (semi-mountable) and Fig 10 kerbs, as well as 3 500 m2 of Armorflex 180, an articulating concrete block system.

Ideally suited for lining trapezoidal channels, a distinctive feature of Armorflex 180 blocks is that they provide a loose, but sophisticated interlocking design. This allows the surface to remain flexible to movement during stormwater or flooding events, safeguarding the overall integrity of the system.
