Paver Repair & Re-Sanding in Clawson

Many Clawson houses off 14 Mile Rd, Crooks Rd and Main St stand only 12 to 15 feet apart, so any pavers on the lot sit close to two things that work against them: roof water and other hard surfaces.

Start with water. A downspout empties a section of roof onto a few square feet, and an eave without a gutter drips along a single line. Concentrated flow like that is one of the ways joints lose their sand, and enough of it can wash out the bedding sand underneath, leaving the pavers above to sink. Bedding that stays saturated also pumps out through the joints under traffic. CMHA, the paver industry's trade association, notes that stabilized joint sand helps hold the joints at downspouts and under eaves. A gutter that spills over its front edge can turn its full length into a drip line, one reason gutter cleaning belongs in the same conversation.

Then the seams. CMHA requires an edge restraint around the perimeter of every paver surface and wherever it meets another pavement, and on a Clawson lot that can mean the edge of an old concrete drive or a shared apron. Where that line is not held, the joints along it widen, the pavers beside it tip or settle, and sand drains into the gap. Refilling those joints does not stop it, because the pavers are still free to move.

In both places, the pavers in the failed strip come up, the cause underneath is corrected, a restraint goes in where one belongs, and the strip is relaid, compacted and re-sanded. Pavers that are level but faded or mossy need restoration instead.
