From driveways to walkways to patios, most homes have concrete laid in either the front or back yards. Over time, concrete can crack, weeds may start to grow and surfaces may sink. When poured, the concrete may have been beautiful, but over time, it can start to look unsightly. Resurfacing concrete involves cleaning and repairing it, then overlaying it with a new surface. The cost of a concrete resurfacing project depends largely on the state of the concrete and the size of the area that needs to be worked on. Resurfacing is significantly less expensive than tearing out old concrete and replacing it with new material.
Most professional concrete companies, such as 4Sons Concrete in Portland, Oregon, DJW Concrete in Sugar Land, Texas, or Kost Services in West Chicago, Illinois, offer repair and maintenance services, including resurfacing and mudjacking.
Steps to resurfacing
Resurfacing is a multistep process that starts with power-washing the surface. Next, cracks and holes are fixed, often with an epoxy mortar, and then the surface is primed and covered with a layer of spray-on polymer concrete, ranging from 1/16- to 1-inch thick. Optionally, the concrete surface can then be colored and sealed.
Resurfacing can also include adding ornate layers such as flagstone, brick or stone patterns in the concrete. The surface can be stamped or etched to look like stone, which is a much less expensive option than laying actual stone. Alternatively, homeowners can have small stones embedded in the new surface.
Some concrete specialists, such as Level Best Concrete Solutions in Crown Point, Indiana, specialize in a concrete-leveling process called "mudjacking." Polyurethane foam is pumped through a concrete slab that has sunk or shifted to support and lift the slab until it’s even again. Then, the concrete can be resurfaced to appear like new.
Concrete contractors generally charge $3 to $10 a square foot for resurfacing, depending on the condition of the original concrete and local labor costs. For smaller projects, some contractors charge a flat fee of at least $500–$1,000. Nationally, the average cost for resurfacing a 500-square-foot driveway ranges from $2,000 to $5,000. The new concrete must also be sealed, which costs $20–$80 a gallon.
Of course, decorative overlays cost more than basic poured concrete, ranging from $4 to $12 a square foot for a stamped pattern, for example.
