Shotcrete: The Solution to Vertically Cut Unsupported Excavations

Safety is Our First Priority

Typical excavations have room to safely slope or step the sides of an excavation. Inner city excavations, and last remaining lots in new subdivisions however, are limited in space and often require straight cut excavations. OH&S regulation states that if an excavation is more than 1.5m deep, the wall needs to either be cut back or a protective temporary structure must be installed. If the excavation is more than 3m deep the temporary protective structure must be designed by a professional engineer.


UNSUPPORTED EXCAVATIONS OVER 1.5m IN DEPTH CAN BE SHUT DOWN BY OH&S AND CITY BUILDING INSPECTORS.
