Proper preparation of the sub-grade is critical to the overall success of the project and the longevity of your driveway. This will determine the final elevation of the finished concrete so that it matches the surrounding areas. Grading creates the proper water drainage for the driveway. It allows for proper load distribution for the new driveway. A vibratory plate compactor is used to compact the base.
The forms define the edges of the concrete and are securely attached to stakes in the ground. During this step the skilled trades people of ALBA carefully assure the proper grade and pitch for your new driveway. This is critical to make sure that the driveway has proper drainage. At this stage the crew will measure for elevation and check the base, all to make sure your driveway will have the proper uniform thickness. In addition a #8 wire mesh is installed and elevated off the ground so it is embedded within the concrete. The mesh provides reinforcement for the concrete driveway.
The forms are sprayed or brushed with form oil and the subgrade is moistened with water before placing the concrete. Once the concrete is placed staightedges are used to screed the concrete. This process removes excess concrete and brings the top surface of the concrete to the proper grade. This is where skill is critical as this work must happen quickly and accurately. If not, the concrete will harden before it is properly finished and overworking the concrete can weaken it.
Whether your new driveway will have a broom finish, hand finish or a decorative finish, this work is done next. It is done once the concrete is stiff and completed before the concrete is hard.
Curing & Sealing:
Curing gives the concrete the conditions it needs during the first few days in order to properly gain strength. Curing and sealing is done immediately after concrete finishing. The specific process used will be determined by the current climate conditions when your concrete is placed.
Joints are placed in concrete to help prevent cracking. With decorative finishes they can be incorporated into designs to be somewhat disguised. For concrete driveways the joints are normally sawcut into the concrete once it has cured.
The lawn area that had to be removed in order to place concrete forms will be replenished.
