Project overview

A Davenport business had a parking lot with a web of open cracks and a surface that had faded to grey. The crew filled the cracks and sealcoated the lot, restoring protection and a clean, uniform finish.

This is routine maintenance done at the right time: before the cracks turned into potholes and before the asphalt needed replacement.

Project details

The crew began by filling the cracks so water could no longer enter the pavement and reach the base. Water in the base is what causes the soft spots, heaving and potholes that show up after a Quad Cities winter.

A fresh coat of asphalt sealer was then applied across the lot. The sealer protects the asphalt binder from oxidation and UV, slows moisture penetration, and gives the lot back its dark, even appearance.

What property owners should know

Preventative maintenance is one of the most cost-effective ways to extend the life of a commercial parking lot. Most lots benefit from sealcoating every two to three years depending on traffic and condition, with crack filling done early, before freeze-thaw cycles widen the damage.

Keep drainage clear so water never stands on the surface, address deteriorating areas promptly, and keep dirt, debris and oil cleaned off. Each of those steps is cheap next to asphalt replacement.
