Efflorescence (white powder substance) can appear on occasion and does not look good on curbing. It is generated from water sprinkling systems and can also appear after a rainstorm. The intensity of efflorescence varies depending upon the type (hardness) or water and the volume of water that gets on the curb. Check your sprinkler heads while the system is on and try to adjust them to minimize the amount of water spraying directly on the curb. If you have just planted sod and are watering frequently, efflorescence may appear more readily. Be patient, wait for the lawn to get established, turn the water off for a few days, and then clean the curb after it dries. A solution of 50/50 vinegar and water with a light brushing will remove the efflorescence. You may have to do this a few times; eventually, the efflorescence should go away.

Cracking – concrete curbing like any other type of concrete can and will crack. We experience very little cracking, outside of the designed joints, in our products; however, if it should crack, we will replace it at no charge during the warranty period. A Warning, however, is important to note: Repairs can be difficult to make in colored concrete. It is impossible to get a perfect color match. Sometimes the “cure is worse than the illness.” A hairline crack is much less noticeable than a patch or discoloration in the curbing.

When curbing is installed as a retrofit (grass already in place) there will be a small amount of concrete on the ground between the new curb and the grass. It is very difficult to remove this concrete while it is still wet. After a 24-hour curing period, it can be picked up in small pieces and thrown away. Since we have not included a return trip in the price of our curbing to do this, we ask that you take a few minutes to remove the excess concrete. This will allow your grass to grow back against the curbing.
