Line Marking Granville NSW

Yes. Granville South Street industrial and Woodville Road commercial carparks are part of our Cumberland City western Sydney schedule. Bitumen patch integrity assessed before marking — debonded patch edges in composite surface carparks cause marking delamination at the patch boundary. We've completed 5,000+ projects nationally since 2009 and carry $20M public liability. Fixed pricing, Transport NSW approved. We've completed 5,000+ projects nationally since 2009 and carry $20M public liability. Every Granville quote includes a site assessment, surface condition report, and fixed pricing. For SafeWork NSW improvement notices we can assess within 24 hours and deploy within 48-72 hours. Completion includes photo documentation, compliance statement, and material specs. Transport NSW approved for all road and carpark marking requiring authority sign-off.

Before marking. A debonded patch will continue to delaminate and marking applied over it will come up with the patch when it eventually lifts. The repair options are: cut out the debonded patch and replace with epoxy mortar (permanent), re-glue the patch to the concrete below with bitumen adhesive and overlay (temporary), or scarify the debonded patch surface to remove the loose layer and mark directly on the exposed concrete below (if the patch is thin enough). We advise on the best option based on the patch type and extent.

Standard thermoplastic adheres adequately to sound, well-bonded bitumen patches after acid etch. Pull-off values on sound bituminous patches are typically 1.4-1.7 MPa — within the acceptable range. The critical issue is patch bondedness, not patch material. A debonded bitumen patch with good-looking surface will produce standard adhesion in the centre but fail at the edges where the patch is lifting.

Transport for NSW approved since 2009. We meet contractor qualification, insurance, and technical standards for state and council road networks.
