Older slabs, shrinkage cracks and settled edges
Ranch homes from the mid-century period often have thin driveways and patios with few or no control joints. After many summers and winters, those slabs develop long cracks, rough surfaces and edges that drop away from the house.
Close to the American River, some ground contains gravel and cobble left by historic dredging. That can make digging slower and may affect how compaction is done. We review each site before promising a method, because a surface overlay suits one slab and a full tear-out suits the next. Wet-season runoff against a slab edge is also a common reason for undercutting, which we look for during every repair visit.
