Concrete Repairs in Northern Beaches
Concrete repairs and concrete cancer treatment across the Northern Beaches. Strata building remediation in Manly, Dee Why, Collaroy and Avalon — done properly so it lasts.
Concrete Repairs in the Northern Beaches, the way we do it
The Northern Beaches has the highest concrete cancer rate per kilometre of buildings in Sydney. Manly, Dee Why, Collaroy and Freshwater all have heavy stocks of 1970s–90s strata buildings, and most balconies and parapets over 20 years old have spalling concrete somewhere. Salt drives chloride deep into the concrete, rusts the steel, and slabs split from the inside out. Cheap patch repairs fail within five years in this environment — the only thing that works is a full cut-back to sound concrete, proper steel treatment with a corrosion inhibitor, salt-resistant repair mortar applied in layers, and a breathable protective coating. We've staged whole-building programs for strata committees across the Beaches, typically running 2–3 years to spread cost across financial years. Membrane work on balconies usually goes hand-in-hand with the concrete repairs.
Manly, Dee Why, Collaroy, Freshwater and Avalon are some of the most salt-exposed neighbourhoods in Sydney. Brick veneer homes, mid-century beach houses, and a heavy stock of 1970s–90s strata blocks dominate. Anything with exposed steel, concrete or untreated brickwork degrades faster here than anywhere else in the metro area. Wind-driven salt also damages render and paint coatings far more aggressively than inland sites.
