Bonduelle Waste Water Tank Relining, Strathroy, ON

Hardrock was contracted to rehabilitate a 40 year old wastewater tank.  The project began with sandblasting the entire tank to remove 40 years of sludge, grime and weathering.  We then installed rebar and mesh on the entire perimeter.  We installed ¼ inch pencil rod to gauge the thickness and screeded the shotcrete once applied.  We then applied a 150mm thick shotcrete layer using a 6hr retarder. The finish was trowelled smooth.
