Adhesive and floating-floor tolerances exist because joints engage over high spots while neighbouring hollows resonate or starve adhesive films. Grinding crowns and bridging valleys with approved leveller restores compliance when underlying structures remain sound.
Survey outputs
Straightedge or laser traverses quantify deviation relative to product datasheets. Spot filling without systemic reasoning invites reflective cracking or bond failure under concentrated rolling loads.
When strip-out wins
Rotten sleepers, contaminated slabs or failed membranes justify systematic removal. Thick leveller stacks masking structural movement rarely age gracefully across Melbourne seasonal humidity swings.
