Bypass Shotcrete

The Sage Condominium in Waterloo required an innovative shoring system that could facilitate a 10m foundation depth with encroachment restrictions. HCM implemented a soldier pile and shotcrete shoring system with a single row of highly loaded rakers.

The use of bypass shotcrete over a caisson wall system advanced the schedule as vertical drilling time was significantly reduced. Shotcrete lagging is advantageous over caisson wall as it reduces the environmental footprint of the project by using less concrete.
