Photo: Choose a concrete resurfacing product. You just need to equip yourself with the right materials and follow the simple steps outlined below. This repair doesn’t require any special skills or previous experience working with concrete. The fix typically involves nothing more than applying a new surface layer to give your driveway a smooth, like-new appearance (and to protect it against future damage). Over the course of a winter, or over the course of years, as the internal pressure rises and falls, it stresses the surface layer of the concrete, which leads to spalling. When the temperature drops below freezing, moisture in the concrete tends to expand, creating internal pressure. After all, spalling starts out as a merely cosmetic imperfection caused by cold weather. If you tackle a spalling problem early on, it’s easy to remedy. If you ignore spalling, it eventually spreads, compromising the integrity of the surface until it is beyond repair, leaving you no recourse but to rip it out and start over. Here, the top layer of the concrete flakes away, leaving the surface patchy and pitted while exposing the aggregate underneath. The good news? What you’re describing-a condition known as spalling-ranks high among the most common issues that afflict concrete. That said, though it can last for decades, concrete typically doesn’t endure without at least a modest amount of care and maintenance. A: Its strength and durability make concrete a preferred material not only for driveways like yours, but for a range of applications, indoors and out.
