River City Sealcoating

River City Sealcoating is an asphalt maintenance company that has operated since 2017, with one crew working around Richmond, Virginia, and a second covering Central New Jersey. It works on residential driveways and commercial lots, and it also installs garage floor coatings.

Driveway sealcoating is the company's main service. It works with SealMaster asphalt emulsion, adding sand to the mix itself to improve traction and give a matte black finish, and a faded driveway can typically be prepped, crackfilled and sealed in one day. Crackfilling uses a polymer-modified rubber brought to 350°F and poured hot into cracks between a quarter inch and one inch wide after they are cleared of debris, vegetation and moisture; a sand broadcast finishes the strips. The company explains that filled lines stay faintly visible through new sealer, and it will not fill alligator cracking, which points to base failure, or hairline cracking caused by over-sealing.

Other pavement services include pothole repair and patchwork, plus complete maintenance packages for commercial lots that include striping to ADA requirements, phased so businesses can keep operating. One documented project was a 195,000-square-foot lot at an active distribution center, finished without any shutdown days. The garage floor system is a four-step flake coating built from epoxy and polyaspartic layers: the slab is ground and primed, flakes are broadcast, and a sealer goes on top.

In Virginia, the company works out of Moseley and covers Richmond along with Henrico, Chesterfield, Hanover, Goochland, Powhatan, New Kent and Amelia counties. The New Jersey crew is based in Piscataway and serves Somerset and Middlesex counties, with select work in Union and Monmouth counties. Quotes are usually prepared from aerial measurements within 24 to 48 hours, so most properties never need an in-person visit. The company uses its own crew rather than subcontractors, offers a two-year workmanship warranty, and will tell owners when pavement does not yet need sealing or when repaving is the better option.
