cement grouting for pipe decommission

Void Filling in Pipe Decommission

Location: North York, ON
Sector: Utilities
Category: Cement Grouting

Description

Following a pipe’s abandonment, a utility contractor discovered a washed out area above the pipe with the potential to collapse in the future and create voids that could lead to a sinkhole. Structural void filling and permanent abandonment works were required.

A bulkhead was designed and installed to successfully fill the pipe and the void using a heavy cement slurry.
