Retaining Wall Replacement Collaroy Plateau

Retaining Wall Replacement in Collaroy Plateau 2097

We work on retaining wall replacement throughout Collaroy Plateau 2097. The service is the rebuild of a wall that has bowed, rotated or failed, done in a way that keeps the ground above it supported while the old wall comes out, and in this suburb one thing shapes it more than anything else. Collaroy Plateau's exposure works both ways — less salt than the beach below, but sustained wind load that makes solid panel fencing a real engineering consideration.

Replacement is more demanding than building new, because the ground behind the wall is already loaded and often already moving. We stage the demolition in sections, support what needs supporting, and correct the drainage that caused the original failure before the new wall goes in. The Northern Beaches walls we replace most often are old timber in sandy ground where the posts simply lost their grip. Rebuilding in the same material at the same depth reproduces the same failure. Collaroy Plateau sits back from the open surf, so the coastal grade matters most on the exposed elevations rather than over every metre of the job. Sandstone sits close to the surface across much of Collaroy Plateau, so posts are often drilled into rock and chemically anchored rather than concreted into a dug hole.

The ground under Collaroy Plateau is elevated sandstone plateau with shallow soil and frequent rock, exposed to strong westerlies, and the suburb is built out with family homes on sloping blocks with elevated ocean and lagoon views. Those two facts decide footing depth, material choice and how long the job takes, so we measure on site before we price anything in Northern Beaches Council's area.
