Get matched with top concrete resurfacing pros in Onida, SD

You can dry pour concrete over existing concrete, but it’s best to use wet pour concrete instead. Dry pour concrete is easier to apply, but in order for new concrete to adhere to old concrete, it needs the right mixture for slow, uniform curing. Additionally, dry pour concrete is less durable and less resistant to cracking and concrete sinking, so dry pouring over an existing slab may result in surface imperfections appearing prematurely.

The easiest way to handle extra-wet cement is to pour it, let it harden, and then recycle it using one of the methods above. You can also crush it down and sell it for base materials, although this can be pretty time-consuming. Your best bet is to start with less concrete than you need and make more as you go to avoid this problem.

Pervious concrete should be between 4 and 8 inches thick to drain water properly. Surfaces like parking lots and driveways should be at least 6 inches thick to accommodate the weight of vehicles, while patios and walkways may be poured between 4 and 6 inches thick. There’s no standard for pervious concrete thickness, but in most cases, the more weight the surface will need to hold, the thicker it should be.

The repair method for a damaged concrete patio depends on the type of damage. For surface cracks, a concrete crack filler is a quick and simple fix. 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.
