Above and Below Ground
Holding the ground we open
Our underground crews bolt, screen and shotcrete every heading they advance. We bring the same people, methods and equipment to the surface: anchoring rock walls on building excavations, shoring soil faces next to streets and houses, and securing portals and box cuts before anyone works below them.
Often it is the same job. Where we drill and blast an excavation, we can also hold its walls, so one contractor answers for the face from the first blast to the last anchor.
What We Install
Ground support, grouting and shoring
Rock & soil anchors
Grouted rock anchors and soil anchors, drilled, installed, plated and tested to the engineer’s design. In broken ground we use hollow-bar anchors that drill their own hole and are grouted through the bar.
Grouting
Cement grout mixed and pumped on site, filling anchor holes from the bottom up and bedding bearing plates on formed grout blocks against rough rock.
Bolting & screen
Rebar and friction bolts on a set pattern, with screen pinned tight to the face so loose rock stays where it is, from a manlift or bolting deck.
Shotcrete
Shotcrete sprayed over screen to seal and hold rock faces on excavation walls, portals and box cuts.
Excavation shoring
Anchored support for building excavations next to streets, utilities and neighbouring properties — soil anchors where the walls are soil, bolts and shotcrete where they are rock.

Ground support & shoring
Dartmouth Shopping Centre — Rock Anchors
Dartmouth, Nova Scotia
Grouted rock anchors holding the rock walls of a commercial redevelopment excavation, installed row by row to the engineer's sequence, plus hollow-bar anchors pumped full of grout where the ground was too broken to hold a hole.

Halifax, Nova Scotia
Shoring and ground support for an apartment building excavation in the city — grouted soil anchors where the walls are soil, and bolts, screen and shotcrete where they are rock.

Your Project
Walls that need holding?
Send us the drawings and the geotechnical report. We’ll price the anchors, grout and shotcrete, and tell you where the design could work better in the ground you have.
