Can every slab crack be patched before flooring?

No. Static surface cracks, active joints, differential cracks, and structural movement require different decisions.

Will a membrane stop a crack from returning?

A product may manage limited in-plane movement within its instructions, but it cannot correct structural movement or guarantee that no finish distress occurs.

Who evaluates a structural crack?

A qualified structural engineer or appropriate foundation professional should evaluate conditions beyond flooring preparation scope.

Slab Cracks Before Flooring | Austin Planning Guide

Learn what to document when concrete cracks appear before flooring, how crack type affects scope, and when structural or moisture review should come first.

A visible slab crack does not reveal whether it is stable, moving, moisture-related, or structurally significant. Flooring planning requires crack width, elevation, location, history, moisture conditions, and the selected floor system. Seek qualified structural or foundation review when there is vertical displacement, rapid change, related wall movement, sticking openings, or other signs outside normal flooring preparation.
