Decision guide

Repair or replace your concrete?

Prepare for an assessment of cracks, settled panels, surface wear, and drainage. Compare what a repair will solve with what replacement changes.

Describe the change before choosing a method

Take a close-up and a wide photo. Record whether the issue is surface wear, a visible crack, displacement, or a low spot collecting water. Note when you first saw it and whether it is changing.

Ask what caused it

A patch, overlay, or sealer may improve the surface without correcting movement underneath. Ask whether the proposed repair addresses the cause or only the visible result.

When limited repair may make sense

An assessment may identify localized damage on otherwise suitable concrete. Ask about compatibility, expected appearance, maintenance, and what remains outside the repair scope.

When to compare replacement

Widespread deterioration, unsuitable supporting conditions, a poor layout, or drainage changes may make a broader project worth considering. Compare demolition limits, base work, and adjoining transitions alongside the finished surface.

Know the limits of a visual guide

This page cannot diagnose a slab or structural problem. Significant displacement or a changing condition near a structure needs qualified evaluation. Keep people away from unsafe surfaces while arranging an assessment.

Common questions

A few good questions.

Will a new coating stop a crack from moving?

A coating should not be assumed to correct underlying movement. Ask about the cause, product suitability, and expected limitations before choosing it.

Will a concrete patch match the old surface?

An exact match should not be promised. Age, material, finish, and exposure affect color and texture; discuss the expected appearance in advance.
