Concrete slab: joints, shrinkage and curling
Plan where concrete can crack/move and recognize when joint-edge lift comes from differential shrinkage rather than a surface-only defect.
VERT / GREEN
Before placement, show joints and slab sequence on the plan.
JAUNE / YELLOW
Random cracks or lifting joint edges can point to poor shrinkage control, curing, thickness or support.
ROUGE / RED
Structural slab, widening/offset crack, major curling or improvised late sawing: diagnose before cosmetic repair.
Quick triage
What the professional checks
The concrete specialist establishes mix, thickness, support, joints, saw timing, curing and tolerances; they distinguish shrinkage/curling from soil or structural issues.
