The concrete driveway construction is gaining popularity day by day over other paving materials. Driveways are an attractive and much-needed component in every house. It looks simple yet elegant and aesthetic. Also known as cement driveways, there are a variety of unique and decorative options that differentiates it from other methods of driveway construction.
To ensure the durability of driveways in Sydney, some important specifications should be followed by the contractor during installation. Quality of workmanship and the material that goes into it is what that largely matters. To get a perfect driveway, here is the list of factors that you can take care of.
- Place concrete at the uniform thickness
Thickness is the foremost factor in determining the structural capacity of a driveway. It should have a thickness of a minimum of 4 inches to 5 inches. Make sure to increase the thickness by 1 or 2 inches at the edges to provide additional support and durability of the driveway as edges are subject to heavy loading most of the time. You can contact your local driveways contractors in Sydney for proper guidance and recommendation.
- Perfect Concrete Mix
A high-performance concrete mix is necessary to ensure the durability of driveways. It may cost you a little bit more per square foot, but it will save large expenses and stress in the long run. You’ll require a low permeability mix to withstand conditions like vehicle traffic, deicing chemical, freezing conditions, etc.
- Finely Placed Joints
Control joints prevent random cracking in the driveways. They should be placed at the appropriate spacing of 10 feet for a slab of 4-inch thickness. These random cracks can be an eyesore, although they won’t affect the service life and durability of the driveway. Joint patterns that have triangular and rectangular sections should be avoided. An isolation joint should also be installed where the driveway meets existing pavements like garage floor slab or the sidewalk.
- Proper Finishing
To achieve uniform finishing of the surface, extra concrete should be struck off. Before the accumulation of bleed water, float the concrete with either a magnesium or wood bull float. Give the finishing touch with the application of a simple broom to improve the traction. Avoid the use of steel trowels at the end as it might do more harm than good to the driveway.
- Proper Drainage System
The driveway should be sloped towards your street and eliminate the standing water. It should be away from structures like a garage, house, etc. Install a proper drain if the drainage is prevented due to the wedges of the concrete slab.
- Curing Technique
Curing of the concrete is the foremost and final step of the process. Concrete should be cured as early as finishing is done. This step is neglected by most of the people but make sure not to avoid the curing. Failure of curing the concrete might reduce the strength of concrete driveways by 50% and increase the possibility of visible defects on the surfaces. Curing includes covering the driveway with wet curing blankets or plastic sheets, sprinkling continuously, and finally applying a liquid membrane-forming compound for curing. Using a liquid curing compound is the most common method of curing.
