For the purpose of this article, we will confine the instructional information for demolition projects to smaller jobs. This example includes the tools and techniques needed to remove sidewalks.
A contractor specializing in demolition may be best suited for certain operations, depending on the amount and complexity of demolition needing to be performed.
Sidewalk demolition can be one of the easiest concrete demolition jobs in the concrete demolition arena. Taking for granted that there will be reinforcing inside the concrete is always the correct assumption when planning for demolition. This knowledge leads us to the list of tools needed to get started.
Before beginning the project, it is imperative that you call the local building department to inquire about any permits needed and most importantly, to find out if there are any utility lines around the work area that may be affected. The utility companies will arrive at the site and mark out the area for reference to any utilities.
A jackhammer will be one of the first tools needed to begin demolition. An electric jackhammer will be sufficient for sidewalk removal. Remember to get the bit (you will need a “point”) when the tool is rented, which will save you a trip back to the rental store. You will also need a heavy duty extension cord for the jackhammer, and most rental companies will have them. Be sure to tell the rental clerk what you are attempting. Rental clerks are very knowledgeable and can help you determine the exact tool you will need for your project.
The tool necessary for cutting the reinforcing in concrete is a set of bolt cutters. Although bolt cutters come in many sizes, the small size will be sufficient for this task. Most demolition tools can be rented at a local tool rental for a minimum cost.
A saw-zall with a metal cutting blade is a handy tool to have while performing concrete demolition. This tool will enable you to cut through reinforcing bars inside the concrete and make the removal task much easier.
A sturdy wheelbarrow, a pick, shovel and a large pry-bar will aid in the demolition project. An 8 pound sledge hammer will also be needed.
Depending on the size of the project and distance away from where you will dump the demolished concrete are factors in considering what type of container will be used to transport the rubble. A larger job would be well served to have a dumpster on site, while a smaller job may only require the use of a pick-up truck.
Beginning the removal of the concrete will require the use of heavy gloves and eye protection. The use of a face shield is recommended during the demolition process. Broken concrete is very sharp and projectiles fly when the jackhammer and other tools are in operation.
Start the demolition process by using the jackhammer to break the concrete into pieces small enough to pick up by hand. Break the entire sidewalk with the jackhammer before beginning any removal.
Pick up the broken pieces of concrete and use the wheelbarrow to carry them to the waste container or truck. If there is any reinforcement in the concrete, use the bolt cutters or grinder to free the broken pieces.
Cleaning up of the small, pebble sized chips is not necessary as the small chips will either be covered with soil, or a new sidewalk.
The more people you can get to help out with the carrying, the faster you will get this project complete, so ask your friends to help with this project.
