Diagnose any concrete crack from a photo — free AI.

The SlabCalc Concrete Crack Analyzer is a free, no-signup AI tool that diagnoses concrete damage from a photo. Upload a clear, close-up shot of a crack and the AI examines crack width, pattern, displacement, staining, and surface texture to classify it against six known failure modes: shrinkage cracking, structural cracking, freeze-thaw spalling, settlement cracking, alkali-silica reaction (ASR), and corrosion-induced cracking. Every diagnosis returns a severity score from 1 (cosmetic) to 5 (structural risk), a certainty percentage, a plain-language explanation, and a clear recommendation on whether DIY repair, a contractor, or a licensed structural engineer is required. When the image is ambiguous between two classifications, the tool defaults to the higher severity — over-cautious rather than falsely reassuring. Built for homeowners, contractors, and inspectors who need a fast first read on whether a crack is cosmetic or serious. Features: - Photo-based AI diagnosis — upload a JPEG, PNG, or WebP (up to 10MB), drag-and-drop or click - Classifies against six concrete failure modes: F1 shrinkage, F2 structural, F3 freeze-thaw spalling, F4 settlement, F5 alkali-silica reaction (ASR), F6 corrosion-induced - Severity score from 1 (cosmetic) to 5 (structural risk) - Certainty / confidence percentage on every diagnosis - Plain-language explanation of the damage - Actionable recommendation: DIY repair, call a contractor, or call a structural engineer - Defaults to the higher severity when the image is ambiguous (safety-first) - Powered by Claude, a state-of-the-art AI vision model - Severity guide, six failure-mode reference pages, and shrinkage-vs-structural comparison - Links through to matching repair guides and material calculators - Free, no signup, no install — runs in the browser How it works 1.
