Rocla rectangular portal culverts were used to rehabilitate a section of the R61 in the Eastern Cape
Reinstating a vital EASTERN CAPE ROUTE
R
ecent heavy rains led to the collapse of a bridge forming part of the R61 at Tsomo Junction between Ngcobo and Cofimvaba in the Eastern Cape and required urgent rehabilitation. As par t of the emergency response, Rocla was contracted to supply 30 rectangular portal culverts. “The team at Rocla double-stripped a RP2100 gang mould so that we could increase our manufacturing output to six culverts per day and get the culverts on the road as quickly as possible,” explains Graham Howell, sales consultant for Rocla in Gqeberha. Measuring 2 100 mm x 2 100 mm, Rocla rectangular portal culverts consist of a deck and two legs placed on a concrete base that can be cast in situ or prefabricated. The standard strength classes are 75S, 100S and 125S. Special intermediate strengths or heavier loading requirements can be designed and manufactured. Additionally, skew culverts can be manufactured for angled road crossings. “The only alternative roads for motorists who used the R61 regularly after the road collapsed were the R409 between the junction and the N2 at Ndabakazi, and the R408 between the N2 at Idutywa and R61 at Ncgobo,” comments Mike Coetzee, regional manager for Rainbow Civils. “The rehabilitation of this section of road therefore required immediate action. We worked with Rocla before and knew the quality of their product. We also knew their manufacturing capability would enable them to respond quickly.” The order was placed in late Januar y 2022 and the first culverts arrived on-site on 4 Februar y, with the last delivered on 15 Februar y. “The culverts were on schedule and were as per our required specifications. Rocla’s ser vice is renowned throughout the industr y, and this R61 project was a per fect example of how they respond to a critical situation,” Coetzee concludes.
