If you're thinking about putting in concrete kerbs around your business or personal property, you need the right supplies. Pouring kerbs is different than pouring flat slabs of concrete. Here are the essentials you need as well as an explanation of the differences between pouring large slabs and small kerbs.
Rebar is a must-have if you're pouring concrete slabs, but it's not as important for kerbs. In fact, you only need rebar for kerbs if they're going to be load bearing. In most cases, this does not apply.
Note that someone walking on the kerb does not make it load bearing. To be load bearing, it must carry very heavy weights such as vehicles.
2. Vapor Barrier
You should lie down a vapor barrier before you start pouring the concrete. This helps to ensure that none of the ground water mixes with the concrete. It is critical in wet climates.
To form the concrete kerbs, you will need moulds. You can buy preformed concrete edging moulds, or you can easily make your own. To make your own, you just need to set up wood frames where you want the kerbs to be.
When pouring a slab, you use moulds to corral the concrete, but they aren't as detailed or small as kerbing moulds.
For the concrete itself, you can choose from a range of types. To get the concrete to match, you should use the same type as you have used for any areas connected to the kerbing.
After you've poured your concrete kerbs, you need to smooth down the concrete. This process removes imperfections from the concrete. It ensures that the concrete looks smooth and doesn't have any unwanted bumps.
For a large slab of concrete, many people run a long plank or a tube over the whole piece of concrete. A trowel does the same job, just on a smaller scale.
6. Groove Cutters
Grovve cutters allow you to cut small grooves in your kerbs. The grooves are built in cracks that allow for expansion and contraction. They help the concrete kerb to last longer. This process is required for both slabs and kerbs.
If desired, you can stamp your concrete. This adds designs to your kerb. You can also do this to big slabs, but obviously, your kerb stamps are going to be smaller.
