Pipe Jacking Sequence

Pipe Replacement

Replacement of collapsed Armco pipe using Pipe Jacking along the Karkloof Road

The existing Armco pipe had deteriorated to the point of complete failure, leaving little support for the road above. Using a trenchless pipe jacking method, BLOC installed a new concrete pipe without disturbing the road surface, which allowed for continued road functionality during the process.

Culvert Jacking

Assembly and installation of large post-tensioned culverts

Due to the size and weight of each culvert, BLOC proposed a cast-in-sections approach. Each unit was manufactured in manageable segments to simplify transport to site. Once delivered, the culverts are assembled and post-tensioned on-site before being jacked into position.
