Installing Very Long Concrete Driveways
Concrete driveways offer many benefits to the owners owing to its durability, low maintenance costs, easy customization and easy removal of snow and ice. Installation of very long concrete driveways may be tiresome, time-consuming if the typical methods and tools are used. It is therefore of importance to hire machinery that would initiate faster excavation, concrete placement, and leveling. Despite this, the steps for driveways installation are as follows
1. Knowledge of the relevant technical aspects
Awareness of the code requirements should be crucial as it provides guidance on the minimum compressive strengths to be attained, and the prerequisite permits that require satisfaction. The confines will ensure that the design and specifications of the driveway satisfy the laid out engineering standards.
2. Site preparation
Once the area is selected with vegetation, there should be the placement of wood forms at the edges of the driveway area. The gravel at the base should also undergo thorough compaction. These activities are aimed at guaranteeing the ultimate drainage and level of the area.
3. Pouring of concrete
Since the driveway is very long, It would be prudent to hire a crew of concrete workers experienced and with the relevant manpower to spread the concrete quickly. The concrete is poured against the form with shovels and hoes for spreading. Overworking the concrete through spreading far is not recommended as this can cause defects in the finished driveway. The long driveways should, therefore, be concrete spread in sections.
4. Striking concrete
This involves moving the strike off across the form to level the concrete. In the long driveway, this is done in batches rather than after complete placement. As the work is done in sections, two people are required for timesaving and a third individual for the collection of other concrete.
5. Smoothing the driveway surface
Use a bull float in smoothening high spots and filling the small hollows; this improves leveling and provides an ideal surface where any type of Finishing based on the needs of the owner is achieved.
6. Edging of concrete
The edge of the driveway should always be regular and commensurate with the formwork. This involves running a masons trowel between outer edges and the concrete, with the forth and back running, it smoothens and compacts the concrete.
7. Jointing of concrete
This aims at controlling cracks since we are doing a very long driveway, jointing is very necessary, as the slab is susceptible to cracks. This will require the setting of joints using a one-inch jointer with a straight guide board. The control joints are made at intervals of 15 times the width but not exceeding 30 times the thickness of the driveway.
8. Curing the driveway
With effective floating of the surface, it should always be kept from drying quickly as this may weaken the surface an initiate crumbling. Since the driveway is long, you can use plastic sheeting to contain the evaporating water; this is effective as continued wetting of the entire surface may be difficult. For cold weather, curing should always take three days longer. A vehicle can drive o the driveways only after ten days elapses.
