Concrete-Driveway Construction Process
Concrete driveway construction is increasing in popularity over asphalt, bitumen or other types of paving materials. Concrete driveways concrete driveway contractors Knoxville tn are also referred to as cement driveways, offer numerous decorative options that help them stand out from other driveway construction methods. This article will briefly explain the specifications for concrete driveway construction.
Concrete Driveway building and construction
To achieve the desired quality in finish, appearance, and durability, the concrete driveway construction must be completed correctly by the contractor. The level of craftsmanship and the materials used in the construction determine the quality and aesthetics of the concrete driveway. These are the essentials for a concrete driveway constructed properly.
Appropriate Subgrade Arrangement
The subgrade has to be laid out to ensure uniformity in soil composition and the level of compaction. It is important to meet this requirement in order to provide adequate support to the load that is pushed across the driveway.
Selecting the Right Concrete Mix
ASTM C-94 advises that concrete driveways to be built using ready-mix concrete. They offer a consistent concrete mix. Random cracking problems are avoided with the right concrete mix.
Reinforcement
Most of the light-duty driveways utilize plain concrete. To increase the structural strength of the driveway, concrete or reinforced concrete companies in Knoxville tn can be used. In areas that have heavy traffic the concrete reinforced driveway is the most suitable option. The reinforcement will not stop cracks from occurring. But the rebars holds the cracks together when they occur and prevents the spread. The reinforcement is placed in concrete driveway either as wire mesh or grid patterns. Blocks can be positioned underneath the rebars in order to aid in locating reinforcement in the center of the concrete driveway. Today the use of synthetic fibers as reinforcement are becoming more popular because they prevent shrinkage cracks to a vast extent. They are not designed to be structural reinforcement but they are able to be used as secondary reinforcement alongside steel reinforcement.
Concrete Position
The strength of the concrete driveway is heavily influenced by the thickness implemented. The minimum thickness recommended for concrete driveways is 4 inches. A structural increase of between 4 and 5 inches will boost the capacity by 50%. This is determined based on specifications and requirements for the driveway.
Properly finishing concrete driveways
Care must be taken during the final procedure of the driveway made from concrete, as most of the work goes wrong due to excessive work on the surface or because of the operation performed over bleeding water on the surface.
Proper Placement of Joints
Control joints that are placed at an appropriate spacing will help to prevent the issues of random cracking. For a concrete driveway that has 4 inches of thickness, the spacing is generally 10 feet. Random cracks are not considered a structural problem. It can affect the aesthetics of your driveway.
Cracks that are random can be avoided by making sure that joints do not have triangular or rectangular sections. The control joints must be 1/4th the thickness of the driveway slab. It is crucial to create isolated joints where the driveway connects with other surfaces or garage floor slabs. Before you begin driveway building, plan your joints.
Adequate Drainage Facility
Concrete driveways are prevented from standing water with the proper drainage plan. Drainage for concrete driveways could be achieved through:
Sloping the concrete driveways toward the street. The side that faces the existing structures must be at high altitude.
A drain must be placed at the bottom of the concrete driveways when sloping is impossible. The water is then diverted.
Correct Curing
The curing process is often overlooked in most concrete contractor Knoxville tn driveways. Curing is equally crucial as the other steps mentioned above. When the finishing process is complete, the surface must be immediately dried.
