Preparing For A Concrete Driveway

Concrete Driveway: Preparing For Concrete concrete driveway Preparing For A Concrete Driveway prepare drivewayWhen the basic concrete driveway design has been decided, the next step is site preparation. As an example, let’s assume that an existing asphalt driveway is being replaced with a traditional, broom-textured concrete driveway. In brief, this is how a typical site preparation works.

The existing thin layer of asphalt is easily removed with a fork-lift truck (or by any method) and carted away. The existing gravel base is reusable, but since the new concrete driveway will be thicker, some of the gravel must be removed to maintain proper elevation.

The gravel base is compacted with a vibratory plate compactor. For a new driveway, a gravel sub base may not be necessary, but the subgrade must be compacted in a similar manner.

Lumber side forms should be placed and securely nailed to stakes in the ground. These stakes should be no more than 4 feet apart and should support each joint in the forming lumber. Measure for elevation and double-check the base to insure uniform slab thickness. One of the chief causes of cracking concrete is an unlevel subgrade.

When pouring your concrete driveway, it’s common practice to match the new driveway so it becomes level with the existing garage slab and sidewalk. However, many of our customers actually prefer their new concrete driveway sit below the garage entrance. The best practice is to keep the concrete below the actual garage floor anywhere from 1/4″ to 1′. The purpose of this is to make sure water doesn’t creep into the garage when heavy rains arise.

An isolation joint is needed where the drive is to meet these existing pavements. Typically 3 1/2″ to 4″ thick premolded joint material is used to make this joint. Joints can also be tooled or saw cut.
