Concrete slabs have many different uses. When you are completing a project that will require a slab, you have the option of using concrete, but some people opt to use asphalt because it is a little less expensive. Some homeowners appreciate the durability and versatility that comes with choosing concrete instead of asphalt.

Concrete Slab Uses

There are many things that you can do with a concrete slab. The slab can be used as a foundation for a building, such as a shed or a garage. It can be used as patio space for entertaining and cooking in the yard. Some people use them for basketball courts or pool decks. The possibilities are pretty much endless, so you just have to think about how the slab will work for your yard.

How To Pour A Concrete Slab

Some homeowners opt to pour a DIY concrete slab. While this might save some money since you don’t have to pay a contractor, you’ll have to be sure you understand all the important points of the project. There’s much more involved than just pouring the concrete into a form.

One of the first things you’ll have to do is determine whether you need cement or concrete. There are important differences between these two that you need to know because it’s imperative that you choose the option that meets the needs of your project.

You have to know when you need rebar or mesh. You also need to familiarize yourself with the process of leveling out the surface of the concrete.

You have to ensure you’re mixing the concrete properly. Read the directions on the brand you choose and find out what the curing time is so you know how long it will be before you can walk or drive on the surface.

Once you have it laid, you’ll need to determine whether you’re going to finish it or not. If you opt to apply a finish, you need to fill any cracks that are in the concrete. This might be done with an epoxy. You'll also need to apply a primer so the finish will stick and be more likely to result in a level surface.

Checking on the concrete slab periodically can help you find defects or imperfections that need to be addressed. Filling cracks and re-leveling the concrete slab as soon as you see cracks or other issues may prevent more serious problems from occurring later.

What Size Crushed Stone For Concrete Slab?

There are a few benefits to adding a layer of crushed stone under a concrete slab. It can improve the lifespan of the slab if it's handled properly. The surface you’re putting the crushed stone on will dictate what size crushed stone you should use. The contractor you work with should be able to tell you what size they will use and why they chose that option. In some instances, a mix of sizes provides the best benefit.

There are three primary benefits to using crushed stone beneath a concrete slab. These include:

  • Reducing the risk of settlement cracking by providing an even base
  • Keeping the surface level by reducing sinking and elemental erosion
  • Preventing pooling by creating a barrier between the ground and slab and providing drainage

Slab Cost Factors

Typically, you can expect to pay anywhere from $4 to $8 per square foot, with most jobs averaging $5.35 to $6.17 per square foot. Labor costs are around an average of $65.50 per hour. The actual total of the project depends on several factors, including the thickness of the slab.

Some professionals will note the price per cubic yard instead of the price per square foot, since the price per cubic yard takes the thickness into account. This cost will average $113 to $126 for the installation and materials.

There might be additional costs of some projects, such as the need for wire mesh or rebar. Concrete slabs that aren’t squares or rectangles might also incur an additional cost. Per project, these are some of the basic average costs:

  • Garage floor: $3,460 for unsealed, with an additional cost of around $1,430 to $2,960 if you want an epoxy sealant
  • Outdoor patio: $2,780
  • Shed concrete floor base: $480
