Surface Defects — Concrete Defect Field Reference Guide

Learn how to identify, assess, and repair the most common surface defects found in hardened concrete with this practical field guide from the Concrete Defect Identification Series.

This illustrated PDF guide is built for concrete inspectors, QC technicians, ready-mix producers, finishers, contractors, field personnel, and anyone responsible for evaluating concrete surface problems. It explains the most common surface defects, including dusting, surface checking, crazing, blistering, bug holes, discoloration, efflorescence, and plastic shrinkage cracking. The guide also explains how to separate cosmetic surface issues from defects that may affect durability, serviceability, or require deeper investigation.

Inside, you’ll find clear explanations of typical appearances, common causes, severity levels, escalation triggers, prevention methods, repair options, and field inspection checks. The guide includes a quick field decision path to help users determine whether a defect calls for cosmetic treatment, surface repair, monitoring, or structural assessment.
