Why Your Paving Stones Have Pits and How You Can Prevent Them

Top Three Causes of Pitting in Your Patio Pavers

When you notice pits in your pavers in Las Vegas, you might wonder how they got there. While paving stones are typically durable and long-lasting, they can experience some damage such as pitting on their surfaces. If you notice pitting in a particular area or extensive pitting, it is important to arrange for an inspection and maintenance of your patio.

Chemical Exposure

Chemical exposure is the leading cause of pitted paving stones in Las Vegas. If you have a fire pit on your patio, the soot and ashes have enough caustic material to cause pits in the pavers. If you wash your car near the pavers, the detergents could cause pitting. Other cleaners that you use on your patio furniture may also damage the paving stones. Severely damaged paving stones should be replaced.

Poor Drainage

While Las Vegas is not known for getting a lot of rain, poor drainage could be a reason why your paving stones have pits. When it does rain, the stones in shady areas may have pools of water sitting on them. This could happen in combination with uneven soil settling underneath the pavers. The pavers in lower areas are more likely to have pits than pavers in higher areas. You could have technicians repair the substrate and level the soil underneath the patio. This could involve temporarily dismantling parts of the patio.

Freezing and Thawing

Las Vegas does not experience too much frost or freezing, but it can happen. Frost may cause expansion of water within the porous paving stones. The water freezes and expands, which can lead to small surface pits. One way to prevent this from happening is to have the patio sealed with a waterproof sealant on an annual basis.
