Structures like carports or garage floors may not need a permit, but they should still be reinforced to withstand the weight and traffic they will endure.

The different types of concrete and when to use them

Different types of concrete and concrete finishes can be used for different applications. The type of concrete you use will depend on the purpose of the area you are concreting, the traffic that will go over it and the look you want to achieve.

Residential concrete: It is ideal for driveways, pathways, patios, pool surrounds and general landscaping. The concrete can be coloured and stamped to create different effects.

Commercial concrete: This type of concrete is used in areas with high traffic, such as shopping centres, car parks and industrial areas. It is a stronger mix that can handle heavy vehicles driving over it.

Concrete finishes: Many different finishes can be achieved with concrete. A few popular finishes include:

Polished concrete is a smooth and shiny finish achieved by grinding the concrete surface.
Exposed aggregate: This finish exposes the stones in the concrete mix, giving it a textured look.
Stamped concrete: This is a finish that can be achieved by using unique stamps to imprint patterns into the concrete surface.
Coloured concrete: This is achieved by adding pigment to the concrete mix or applying a coloured sealer to the surface.

How to prepare for a concrete pour

Preparation needs to be done beforehand to ensure a successful pour. These are the key steps:

Clear the area of any debris or obstacles.
Mark out the area where the concrete will be poured.
Excavate if necessary to create a level surface.
Prepare the sub-base by compacting it and adding a layer of gravel if necessary.
Install any reinforcement, such as steel mesh or rebar.
Connect any expansion joints that will be used.
Prepare the forms that will contain the concrete.

The type of construction you are doing will determine how to pour your concrete, but those are the typical steps involved in preparing for a pour.

The process of concreting, from start to finish

Once you are ready to pour, the process is relatively straightforward:

Start by mixing your concrete according to the instructions.
Fill the forms with concrete using a shovel or similar tool.
Tamp down the concrete to remove any air pockets and level it off.
Finish the concrete by smoothing it with a trowel or similar tool.
Let the concrete cure for the recommended amount of time.
Remove the forms and enjoy your new concrete surface!

As you can see, concreting is not a complicated process. However, it is essential to follow all instructions carefully to ensure your project turns out the way you want it to.

Tips for maintaining your new concrete surface
