If a contractor is planning to use shotcrete for a project, there are some basic requirements that must be met. Pre-construction meetings are the first requirement. These meetings will be arranged by the engineer prior to the beginning of the work.
The surface that will be cure must be cleaned thoroughly. This is to ensure that the shotcrete bonding process is not affected by any growths, voids, or other material. Concrete that isn't asphaltic or reinforcing metal 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 has been prepared the contractor must supply all necessary equipment, labor, as well as materials. The contractor must also have sufficient shotcrete to meet project specifications. A ready-mix truck is typically used by contractors to transport materials to the job site. Other equipment may be needed depending on the project.
A contractor will need to use many different methods to prepare a surface in shotcrete. High pressure water blasting, abrasive blast cleaning, and chippinghammering are all suitable methods.
The shotcrete should be placed over existing structures, but not directly on them. You will need to cover the shotcrete with an impervious layer. It should be cut approximately 45° from the surface.
Once the surface has been prepared for shotcrete, the shotcrete sprayer should be pointed perpendicularly towards the face. Unless otherwise noted, shotcrete must be applied starting at the bottom and working upwards. Sometimes additional layers may be applied to repair work areas that are not as thick.
The shotcrete must adhere to surfaces without flowing and should have a rich, glossy look. To control the consistency of shotcrete, you can add pozzolanic to the mixture. You must also control the amount of water that is added to the mixture.
Before placing shotcrete, the contractor will need to perform a series of tests. Each panel must measure 3 1/2 in thick and include 2-#4 bars. A qualified team must perform the test panels. They must also provide all materials necessary for the project as well as perform coring. The Engineer will approve the test panel so that the shotcrete contractor may proceed with the repair to the substructure.
The Engineer must be notified by contractors before they apply shotcrete. This will allow the Engineer to inspect the preparations and determine if the work is satisfactory. Any repairs not acceptable might be stopped.
The contractor must ensure that the surface is consistent from batch to batch. Shotcrete that's too thick or too thin will not be strong enough to withstand any stresses during construction. The temperature of the shotcrete should not exceed 90 degrees Fahrenheit.
FAQ
What are the payment terms for the service/contractor I am required to pay?
The type of service provided will determine the payment schedule. If you hire a contractor for a roof installation, payments would be made as soon as the work is completed. However, when you purchase a product from a seller, such as a kitchen range oven, you may only pay once you have received and tested it.
Do you have any other suggestions?
Yes. Check your local laws to see what types of projects are allowed and what conditions must be met. Some states require that you get council approval before you build. Others say you just need to inform them of your plans. To find out their position on the matter, check with your local authorities.
Who has to pay for the service?
Your SCA defines who is responsible for paying for the service. The service provider may be entitled to compensation if it isn't paid in full.
