How A Concrete Contractor Installs Your New Patio

Gregory Walker

Even if you don't spend a lot of time outdoors, a patio would be a nice addition to your home. The concrete slab would give you a level and safe place to set up a grill, and the patio could be used for other purposes too. Installing a concrete patio involves a lot of work that can be labor intensive, but it's routine work for a concrete contractor. Here's a look at some steps necessary for adding a patio to your home.

Strip The Grass And Compact The Soil

One of the most time-consuming parts of installing a patio slab is getting the ground ready. It's important to do this job right or the soil may shift once the slab is in place and cause the concrete to crack or sink. First, the grass has to be removed from the area to uncover the bare soil. Then, some of the soil has to be removed. The reason soil is removed is to allow room for a layer of gravel under the concrete for drainage purposes. Also, you want the patio to be flush with the ground rather than a few inches above it.

The amount of soil that needs to be dug up and removed depends on the type of soil you have because some soils drain more readily than others. Clay doesn't drain well, so more of it has to be removed so a thicker layer of gravel can be added than would be necessary for sandy soil. Once the soil is at the right depth, it's time to tamp it down to compact it. After that, gravel is spread on the site and tamped down. The end result is a compact and stable bed for the concrete to rest on.

Build The Frame And Add Rebar

It's necessary to build a frame around the perimeter of the space that will be your new patio so there's something to hold the concrete in place while it is damp and runny. The frame consists of boards that outline the shape and size of your patio, so when the frame is in place, you'll have one last chance to visualize how your patio will look before the concrete is poured. Another step necessary before pouring concrete is to add rebar to the bed. Rebar adds stability and gives the concrete a stronger base to rest upon. It doesn't rest on the ground because concrete needs to get under it as well as over it, so the bars will be elevated by placing small risers under them.

Pour And Level The Concrete

Concrete for a patio may be delivered by a mixing truck so it is ready to be poured. This ensures the concrete has a consistent quality over mixing up small batches at a time in a wheelbarrow. The concrete is spread over the bed and the surface is flattened so it is level and even with the top of the side frames. This work usually goes fast so the concrete can be put in place before it starts to get dry and hard. Once the concrete has hardened, the form is removed and the contractor lets you know when your patio will be ready to use for outdoor cooking and dining.

Hi, I'm Caroline. Welding has always been really fascinating to me. One day, when I was at work in my office, we had a leaky pipe in the ceiling. After calling a plumber, he called a welder who came to repair the large, open pipe. As we were all sitting there trying to work, the welder just came in and started repairing the pipe! I had never worked on a construction site before, and I probably never will. But I started thinking about what it would actually be like to work on a construction site, which led to me exploring construction themes and writing this blog!
