Narrow lots, alleys and a high water table
Lots here can be tight, and some streets have alley access or limited room for a truck to back in. Concrete trucks are heavy and the chute only reaches so far, so access often decides whether a job uses a pump, wheelbarrows or a different pour sequence.
Ground conditions matter too. Much of the peninsula is low and sandy, and the water table can sit close to the surface after a wet summer. Standing water under a slab can soften the base and push moisture up through the finished surface. Tree roots from mature oaks add another pressure, since they can lift a slab edge over the years. We look at all three before suggesting thickness, reinforcement and drainage.
