One of the first signs of damage to a concrete patio is surface cracking. If this occurs in a wide area, it may signal a bigger problem beneath the surface. While small cracks can be filled with epoxy filler, deeper cracks may require professional intervention. The strength of a concrete patio is affected by a variety of factors, including tree roots and the soil underneath the patio slab.
Cost of replacing a concrete patio
Costs for a new Concrete Patios Charleston can vary greatly. Some people calculate the costs by the cost of the contractor, but almost always the price is based on the square footage. If you’re thinking of replacing your patio with a new one, make sure to get a few different quotes from contractors before you make the final decision.
If the patio is situated on an uneven or hilly site, preparing the ground may prove to be a complicated process. You may need to build up lower areas or erect retaining walls. Also, you may have to remove existing structures and natural barriers. These costs can add up depending on the size and weight of these obstacles. For instance, removing an old dog house can cost as little as $100, but removing a tree root could cost thousands of dollars.
In general, concrete is a strong material that’s reasonably priced. But if you do happen to notice a crack, it can get very costly. Crack repair can cost between $100 and $300. Crack fillers can help prevent bigger cracks from developing and are also a great option if you’re worried about the overall look of your patio. In addition, it’s possible to repair holes in a concrete patio by applying a new topcoat or filling them with another material.
Symptoms of damage
A concrete patio can show signs of damage over time. Cracks in the surface can indicate more extensive damage. Cracks can be caused by several things, including the settling of the subgrade or heavy weights placed on the patio. The first step in repairing concrete damage is to identify the source of the damage.
Fire can also damage Concrete Patios Charleston SC. Heat draws out moisture from concrete, creating small pockets of air that create cracks. Additionally, fire can also damage the aggregate in the concrete. This can cause the concrete to expand or break down, depending on the content of the patio. For example, some quick-mixes contain limestone, which breaks down when exposed to high heat.
Cold weather is another factor that can affect the concrete. It can make the surface look cracked and become unsafe. Ice also causes problems because it expands nine percent when it freezes. The increased pressure can cause cracks in concrete, which will only become larger as the winter goes on. Another cause of damage to a concrete patio is the use of salt. It is not recommended to use salt on a concrete patio, as it can affect the color and strength of the patio.
Once the base is sealed, apply a topcoat sealer. This will protect the concrete stain colors and make the new surface durable. The topcoat sealer should be UV-resistant and penetrate every nook and cranny of the surface. It’s best to apply two coats to the entire surface for optimal durability. Remember, however, that the new concrete overlay is only as good as the surface underneath. Make sure that the surface is clean before applying the overlay.
