Richmond concrete faces a mixed climate — humid summers, real-but-moderate winters, clay underneath — and its maintenance mistakes are correspondingly mixed. These are the ones that show up in repair calls, ranked by the damage they do.
Letting the clay get thirsty then flooded
Virginia clay swells and shrinks with moisture, and slabs ride the motion. Downspouts dumping beside the driveway, irrigation soaking one edge, or a summer drought followed by tropical rain all move the ground — and gutters, splash blocks, and stable grading are concrete maintenance here as much as anything done to the surface.
Treating sealer as optional
A penetrating sealer every four years or so keeps water out of the pores through winter freezes and summer algae season alike. It is an afternoon and a pump sprayer on a DIY basis — and its absence is legible in every scaled, gray, moisture-streaked driveway on the block.
Winter shortcuts
Richmond freezes enough to matter: rock salt on young concrete, metal shovel edges on stamped work, and ignoring refreeze puddles all leave spring evidence. Calcium chloride sparingly, plastic edges, and fixing the puddle's cause cover the season.
Deferring dollar repairs into thousand-dollar ones
Open joints and cracks admit water to the clay; wet clay moves; moved slabs crack wider. The loop runs on neglect and stops with a tube of polyurethane caulk the first season a crack appears. A yearly one-hour walk — clean joints, caulk cracks, note any new movement — is the whole preventive program.
The yearly hour, scheduled
Pick a spring Saturday: wash, clear joints, caulk new cracks, check where the gutters discharge, reseal on the four-year cadence. Clay-country concrete rewards exactly this hour and punishes its absence with interest.
