Patching the Cracks Sidewalk Repair & Maintenance

Given the thousands of miles of sidewalks running through New Jersey's suburban communities, sidewalk maintenance in this region is serious business.

What are the factors that contribute to buckling, cracked, and uneven sidewalks? How can boards and managers keep their own stretch of concrete in good repair to avoid unwanted legal drama? Let's take a look.

After the formula was lost during the Dark Ages, along with just about everything else one identifies with civilization, concrete was re-discovered in Britain in the mid-18th century. Modern concrete is usually a combination of Portland cement, fly ash (a by-product of coal power plants), gravel, sand, special chemicals that do things like make new concrete bond to old or give it a brick-colored hue, and water.
