It was hard for the home inspector not to stop and take a photo of this side yard walkway in Fremont.
Nearly every backyard concrete patio and driveway will crack after installation, if not properly installed. What happens?
A number of factors cause concrete flatwork to develop cracks, offsets and to settle:
- installing directly on soil – which expands when wet, shrinks when dry
- inadequate preparation –not adding a 4” gravel base
- not installing reinforcing steel mesh
- poor drainage control – downspouts discharge water next to walkway
The large crack was a result of poor drainage and ground settlement.
It was classified as a walking safety concern and a liability.
