Rebar is metal bars that you can use to reinforce concrete. In some cases, you should definitely use rebar, but in other cases, you can save a bit of money and skip the rebar. Here are four signs you should use rebar.
1. Your Patio Is Old & Needs Touching Up
If you have a tired old patio or a sunken driveway, you can revitalise it by adding a new slab of concrete on the top. In this case, you should use rebar to tie the two slabs of concrete together. There are a number of ways you can do this, but you may want to try drilling holes into the existing slab and putting short pieces of rebar into those holes.
This can work when putting two slabs next to each other or when pouring a new slab on top of an old one. Make sure that the rebar doesn't stick up past the level of the new concrete. When the rebar is firmly in place, simply pour the new concrete as usual. It will harden around the rebar.
2. You're Working in an Area With a Diverse Climate
Rebar helps hold concrete slabs together when the climate tries to pull them apart. Essentially, as the weather in your area gets very cold, water in the concrete can freeze, causing the concrete to expand. Then, when temperatures rise, the water evaporates, causing the concrete to shrink. This cycle of expansion and contraction can cause cracks or potholes in the concrete, but rebar can help prevent that.
3. You're Addressing Wet or Weak Soil Conditions
Even if the climate is not extreme, you may want to take into account soil conditions when deciding to use rebar. In particular, if the soil is very weak or wet, you should use rebar to strengthen the concrete. If the soil is relatively dry and firm, you may be able to get away without using rebar, but in these bases, you need a firm base for the concrete. For example, a bed of gravel between the soil and the concrete can help with stability and drainage, and a moisture barrier can help prevent moisture from migrating from the soil to the concrete slab.
4. Your Concrete Isn't Complying with Local Building Regulations
In addition to surveying your project's need for rebar, you should also check with local building regulations. In most cases, you are required to use rebar in columns and concrete walls, but there is a lot of code variance when it comes to concrete slabs. For example, you may not be required to use rebar in a small walking path, but you may need to use it in a slab for a driveway. Note that is just an example to show how possible codes may differ from each other. It is not based on actual laws.
