What goes into a paver patio that stays flat in Michigan
Most Troy homeowners adding a new paver patio start with one of three site conditions. Either lawn that needs to be excavated down to subgrade, an old wood deck that is coming out, or a failing stamped concrete pad that needs to be broken up and hauled. The site condition changes how much excavation is needed. But the base spec stays the same. A residential patio in Oakland County needs a 6 to 8 inch compacted aggregate base. The pavers themselves can be a 60mm Unilock-style residential paver. Cut perimeter, screeded sand bed, polymeric joint sand. Anything thinner on the base fails inside a few seasons on Michigan clay soil.
A proper paver install runs in a clear sequence. First, the site gets excavated down to undisturbed subgrade and graded with a quarter inch per foot slope away from the house. 6 to 8 inches of crushed limestone (21AA or 22A in Michigan) goes down, compacted in 2 to 3 inch lifts so it locks together. A one inch bedding sand layer gets screeded perfectly flat off rails laid on the base. Pavers go down in the chosen pattern. Herringbone is the strongest, locks under load, and is the right call for any patio that will see a wheelbarrow or a heavy grill. Running bond and basketweave are foot-only and look more relaxed. Perimeter pavers get cut on a wet saw to the patio outline. Edge restraints (plastic L-edge anchored with 10-inch spikes, or a soldier course of pavers set in concrete) lock the perimeter. Polymeric sand gets swept into every joint and watered in. The patio is walkable the same day; full furniture load the next.
- 6 to 8 inch crushed limestone base compacted in 2 to 3 inch lifts, never a single dump-and-roll pass.
- One inch screeded bedding sand, never a thicker bed that lets pavers rock under load.
- Herringbone pattern for any patio with vehicle or heavy-load traffic; running bond or basketweave for foot-only.
- Anchored edge restraints along every perimeter, never just sand against turf that lets pavers wander.
- Polymeric sand swept into joints and watered in, never plain mason sand that washes out in two rains.
Troy and the surrounding Oakland County cities (Royal Oak, Birmingham, Bloomfield Hills, Rochester, Rochester Hills, Madison Heights, Clawson) all sit on the same heavy clay soil that wants to settle around any foundation that is not on a deep aggregate base. Reputable paver contractors in this area write the base depth, the paver brand, the joint sand type, and the edging method directly into the quote, not as a verbal promise. A bid that just says paver patio with a price is the one missing the layers that matter.
