Culvert Jacking

Esor Construction can install box culverts for utilisation on stormwater systems, combined pedestrian / bicycle access ways and vehicular traffic tunnels.


  • Box Culverts can be jacked under surface infrastructure using similar techniques to pipe jacking. Box culvert installation can be utilised for:
    Pedestrian underpass
    Pedestrian / Cycleway underpasses
    Trafficable tunnels
    Stormwater systems


Pre-cast or cast on site box culverts are jacked into position using high-capacity hydraulic jacks pushing from the launch side.

City of Tswane required 3m x 3m Jacking Box Culverts to be installed beneath Rodger Dyson and Voortrekker Street in Pretoria for a water service pipeline using trenchless methods.

This method was chosen so that heavy traffic in this area could not be disturbed in any form or way.

Esor Construction, the only company equipped and experienced for this type of jacking was appointed as the sub-contactor responsible for the installation of the culverts.
