Paver Repair & Re-Sanding in Casco Township

Farmland and rural residential land cover about 78% of Casco Township, and zoning sets minimum lots of 2 acres in the R-1 and R-2 districts and 5 in the agricultural district. On a lot that size a paver patio can sit out in the lawn: the house wall, which CMHA accepts as a restraint, may hold one side while grass meets the rest. CMHA's edge restraint note requires a restraint along the perimeter and wherever the paving meets another material, to hold the pavers tight through traffic and freeze-thaw. Soil backfill, it says, is never a suitable restraint.

A failing edge has a recognizable pattern. CMHA's maintenance guide describes joints that widen at the outer edge, edge pavers that rotate or settle, and sand lost from the gaps, most noticeable within a foot or two of the edge. When we see it, the first question is what the border was held with. CMHA rules out landscape bed edging and any edging set on top of the bedding sand, and advises against timber, which warps and rots. Spikes belong in compacted base, never in soil, and the base should run past the restraint by at least the base's own thickness, so a 6-inch base reaches 6 inches past the spikes.

A concrete edge troweled against the outer row looks solid, but CMHA lists a troweled edge only where the ground does not freeze, so the repair uses one of the restraints it accepts for homes. Low spots in the field of the patio are a separate question. On ground near the county drains that carry water toward Swan Creek, or by the Belle River floodplain in the northeast, a saturated base is one of CMHA's causes for a dip, and the fix is the base, not extra sand.
