What Type Of Concrete Is Used For Curbs?

Choosing the right concrete for your curb is key to completing a project to the suitable quality standard. This article explains the key considerations. 

Are you installing a curb around a property or residential area? If so, it is important to ensure that you use the right type of concrete. The wrong concrete will mean that the curb is not durable and does not provide the long-term benefits you require here. 

Choosing the right concrete grade will ensure that you create a robust curb. The composition and strength of the concrete are the factors that distinguish the different grades.

What Type Of Concrete Should You Use?

The most common concrete mix is called the “curb mix.’’ This is made up of cement, water, fibre and sand. As such, it does resemble mortar when it is correctly mixed. Remember, to ensure that you produce the right concrete, and you must guarantee that you get the right ratio of the different substances. If you don’t, it will lead to the wrong strength and composition. 

Reinforced concrete is also often used for curbs. This is because curbs are expected to see a high level of foot traffic. As such, it is important to ensure they will stand the test of time without developing any issues such as cracks. 

Should You Reinforce A Concrete Curb With Steel?

Typically, reinforcing a curb with concrete will not be required. However, formed curbs are reinforced using bars of steel. If this is the case, they must be secured and positioned within the forms. The aim is always to ensure that the reinforcing concrete is not displaced during the consolidation or placement of the concrete. 

An alternative would be to use wire mesh to reinforce the concrete. The issue with wire mesh is it may not provide the same level of strength. As such, it can result in a weak concrete foundation for your curb overall. 

Should A Concrete Curb Have Gravel Underneath it?

Another question to consider is whether or not you need gravel as a foundation for the concrete. The right base of gravel can provide significant benefits. For instance, it may prevent the concrete from shifting or cracking over time. Essentially, if you pour the concrete over a gravel base, you can guarantee that it will remain durable. Gravel can also be more important depending on the ground where you are laying the concrete. For instance, you might add the curb on clay soil. Since clay soil doesn’t typically drain well, it can cause water to pool under the newly laid concrete. This can cause the soil to erode slowly.
