ANDERSAL PTY LTD serves Alexandria, NSW on government, industrial, commercial and strata projects from $15K to multi-million-dollar in scale, including concrete cancer repair and waterproofing. Its own site says it is not resourced for minor repairs to private residences.
In greater Sydney, older apartment blocks and balconies see a lot of concrete cancer, while reactive clay suburbs see more footing movement and cracking.
As a 2025 guide, typical underpinning runs about $4,000 to $15,000 and concrete cancer repair varies widely with access -- a guide, not a quote. See the cost guide for the detail.
Use the provider's current licence, insurance and written scope as part of the hiring decision.
ANDERSAL PTY LTD's listing here covers Concrete cancer repair, Waterproofing and Strata / apartment experience. Treat that as a pointer for comparing specialists rather than a confirmed scope of work, and check directly what they can take on.
This directory carries name, city and service focus only, not licensing or insurance verification. Ask ANDERSAL PTY LTD for their current licence and insurance details directly, and check them against your state's building regulator if you want independent confirmation.
For anything beyond hairline cosmetic cracking, yes. A structural engineer independently diagnoses whether footings have moved and why, and specifies the repair; a contractor like ANDERSAL PTY LTD then prices and carries out that repair. Getting the engineer's report first means every quote you get, including from ANDERSAL PTY LTD, is priced against the same diagnosis.
Underpinning and concrete repair are quote-driven work, typically $4,000 to $15,000 for common residential underpinning jobs, but method, soil and access swing the number a lot. Get a written quote from ANDERSAL PTY LTD or any contractor you compare, and check it against our cost guide.
