For larger cracks or uneven slabs, you may need to hire a professional to pump a cementitious material under the sunken portion to lift it back into place. For heavy spalling and other surface damage, resurfacing may be the best and most affordable option. This includes pouring a new layer of concrete over the old layer.

Yes, you can pour new concrete over an existing concrete patio. This process, known as resurfacing, is a common repair method used by professionals. For the best results, ensure the old concrete surface is clean and free from debris. The new layer of concrete should be at least three to four inches thick and include reinforcement materials, such as fiberglass fibers or wire mesh, to prevent cracking and spalling. With proper technique, a resurfaced patio can last for 15 to 20 years.
