About SlabCalc Concrete Crack Analyzer
SlabCalc Crack Analyzer - AI Concrete Crack Diagnosis
Introduction
SlabCalc's Crack Analyzer is a free, AI-powered tool that diagnoses concrete cracks from a single photo. Upload an image of a crack in your driveway, slab, patio, or wall, and the analyzer identifies the crack type, assesses severity, explains the likely cause, and tells you whether it's a cosmetic issue or a structural concern that needs a pro.
Built for homeowners, contractors, and property managers who need a fast second opinion before deciding whether to seal, patch, or call a structural engineer.

FAQs
Is the analysis accurate enough to rely on? The analyzer is a first-pass diagnostic - excellent for triaging whether a crack is cosmetic or warrants a closer look. For anything flagged as structural or load-bearing, always confirm with a licensed structural engineer.
What kinds of cracks can it identify? All the common ones: shrinkage (plastic and drying), settlement, structural/load, map cracking, crazing, D-cracking, and surface scaling. Each comes with its own dedicated guide.
Does it work on photos from any device? Yes - phone, tablet, or DSLR. Better lighting and a closer crop produce more confident results.
Is my photo stored or shared? No. Photos are processed for the analysis and not retained or used for training.
Do I need to know anything about concrete? No. Results are written for non-experts - but they include the technical reasoning so contractors and inspectors get value too.
What if my crack isn't in the library? The analyzer will still classify it to the closest match and explain the reasoning. You can also reach out via the contact link with edge cases.
