Concreting Adelaide: Concreting Tips for Driveways

If you want your concrete driveway to last, be sure not to park heavy equipment or trucks on it for a few days. It will prevent the concrete from settling and becoming weak. Once the concrete is poured, it needs to be levelled and tamped. A wood float or magnesium hand float is used to smooth the surface. Cut control joints early in the process; for a four-inch slab, this means cutting them every eight feet.

Preparation

The sub-base, or foundation, of a concrete driveway is crucial to its longevity. In driveway concreting Adelaide, it should be well-graded and compacted, using materials that are consistent with your soil condition and climate. For example, if you live in a climate that experiences extreme cold, or your driveway will have heavy vehicles regularly parking on it, you may need to increase the thickness of the concrete.

Once the form is assembled, stakes are placed at 4-foot intervals along the path of the driveway. It allows you to create a level surface for pouring the concrete. You may also want to use a vibratory plate compactor and rammer to ensure the ground is level and dense before you begin laying your concrete.

After the forms are removed, a wood or magnesium hand float is used to create a smooth finish on the concrete. It helps to reduce tripping hazards and gives the concrete a clean look.

To prevent cracks, protect the concrete from extreme weather conditions until it has cured. You can help to speed up this process by watering the concrete regularly and covering it with a wet curing blanket or layer of plastic sheeting.

Mixing

Concrete must be mixed properly in order to get the right consistency and strength. Skilled concreting contractors will use a drum mixer that mixes the concrete continuously to ensure a consistent texture and quality. The mixer will also agitate the mix to reduce bubbles and air pockets that can weaken the final concrete.

When the concrete is ready to be poured, it must be transferred to your site as quickly as possible. A concrete pump may be needed to ensure the delivery is made quickly and evenly.

Once the concrete is poured, it must be screeded to achieve a smooth and uniform surface. Depending on your desired finish, workers may use power tools or brooms to roughen the concrete surface at just the right time in the set process to produce different textures.

During the curing process, it is important to keep the concrete moist so that it doesn’t crack or damage. It can be done by spraying the surface with water, covering it with wet burlap, or using a curing compound.

Pouring

Once the base is poured and the forms are set in place, it’s time to pour the concrete. The ready-mix concrete is poured straight from the truck’s chute into the formwork, and it should be level with the tops of the forms.

If you want a more durable concrete driveway, the team may also lay steel mesh – called rebar – over the entire area before the concrete is poured. It adds to the overall cost of the project but dramatically increases durability by spreading the weight of vehicles evenly over a larger surface area.

To prevent concrete cracking after it sets, the concrete contractors will install control joints within the slab. It helps reduce the number of cracks and will allow the concrete to bend slightly without breaking or collapsing. The minimum distance between control joints is 8 feet, but a more precise calculation is used depending on the size of your concrete driveway and whether it is square or rectangular.

Finishing

Once the concrete has set slightly (depending on the weather conditions), it is time to finish the surface. Using a wooden or magnesium bull float, the concrete can be finished to a smooth finish. Alternatively, a course brush can be used to create a more rugged texture in driveway concreting Adelaide. This type of finish is particularly good for driveways as it offers better traction and helps prevent accidents due to slippery surfaces when wet.
