Concrete kerbs and driveways are a great option for any property. They make parking and driveways a lot smoother, quieter and more attractive. Construction of such a driveway involves these steps:
Heavy machineries such as forklifts, bobcats, trucks and loaders will be used for the demolition and removal of debris.
Preparing the surface for appropriate water drainage. The surface will be graded to ensure that water runs off smoothly. This will help prevent cracks, potholes, and heaving.
Sub-base is one of the most important parts of driveway construction. It will provide a stable surface to support the new pavement and driveway kerb edging. It also acts as a foster barrier to help reduce winter damage due to thawing and freezing.
- Proof roll, undercutting and sub-base repair
Once the sub-base is compacted and graded, proof rolling will be done. It involves driving a fully loaded dump truck row by row over the entire surface. If the gravel flexes more than an inch under the weight of the truck, it means the base is not supported properly. Soft spots will be removed using undercutting. It involves digging and replacing the underlying soft clay with a stronger material.
- Binder and surface course
Once the soft spots are repaired and the sub-base is laid out thoroughly, it is time to add the binder. It will be a layer of large aggregate mixed with oil for strength and durability.
- Installing the new surface
A top layer will be added to provide a smooth and clean ride. The layer will be made of small aggregators, sand and oil.
The entire surface will be compacted and smoothened using a roller truck. This will ensure that there are no small aggregator bumps or stone poking through the new surface.
