Crack in slab foundation — Barcelona, Catalonia
A crack running through a concrete slab foundation can signal differential settlement, soil shrinkage, or excess hydrostatic pressure beneath the slab. Even hairline cracks may widen over time, allowing moisture and radon gas to enter the home. A foundation specialist can evaluate the crack pattern, determine whether the settlement is active, and apply the appropriate repair — from epoxy injection to pier underpinning.
