Description
Rocla’s custom designed jacking culverts are the largest to be manufactured in South Africa. The customer required 3m x 3m custom-made jacking box culverts for a service delivery project. The culverts were manufactured with an in-the-wall joint that can be sealed with a rubber ring if required. They were used to create two 50m long under road tunnels, 6m below the road surface in order to provide new water services.
