A contractor who plans to use shotcrete on a project must comply with these basic requirements. Pre-construction meetings are the first requirement. These meetings will be arranged by the engineer prior to the beginning of the work.
Next, you must clean and dry the surface. This is to ensure there are no voids, growths or other materials that can interfere with the bonding process of the shotcrete. For example, reinforcing steel and concrete that is not asphaltic must be removed. Also, the surface must be clean and leveled. For any left-over spray, you can use a stiff bristle scrubber.
Once the surface is prepared, the contractor must then provide all the equipment, labor, and materials needed for the project. Contractors must have adequate shotcrete for the job. A contractor will usually use a readymix truck to transport materials to the site. Depending on the type of project, other equipment may be required.
Contractors will need to use several techniques in order to prepare a surface for shotcrete. Abrasive blast cleaning, high pressure water blasting, and chipping hammering are all appropriate methods.
No matter if the shotcrete will be applied on top of an existing structure, or in place, it is important that the surface not dry immediately after application. You will need to cover the shotcrete with an impervious layer. The material should be cut to approximately 45 degrees from the surface.
Once the surface is prepared the shotcrete gun should be pointed perpendicularly at the working face. The shotcrete will be applied upwards, unless otherwise indicated. You may occasionally need to add layers of shotcrete to repair portions of the job that are not as thick.
The consistency of the shotcrete must adhere without flowing to the surface. It should leave a rich, glossy appearance. The consistency of the shotcrete can be controlled by adding pozzolanic material to the mixture. It is important to control how much water is added to your mixture.
The contractor will need a series tests before placing shotcrete. Each test panel must be 3 1/2 inches thick and contain 2-#4 bars on each side. A qualified team must perform the test panels. They should also provide all the materials required for the project and conduct the coring. The Engineer will approve the shotcrete contractor's test panel and the substructure contractor can proceed with repair.
Additionally, shotcrete must be provided to the Engineer by contractors prior to applying it. This will enable the Engineer inspect the work and make a decision about whether it is satisfactory. Reparations that aren't acceptable could be stopped.
Finally, the contractor should ensure that each batch has a uniform surface. The shotcrete will not be able withstand the stress that might be encountered during construction. Keep the temperature of shotcrete at 90 degrees Fahrenheit.
