There are some requirements that contractors must meet if they plan to use shotcrete in their projects. First, you must attend a pre-construction meeting. The engineer will organize these meetings prior to the actual start of the work.
Next, you must clean and dry the surface. This is to ensure the shotcrete bonds well and that there are not any voids, growths, or material that might interfere. Concrete that is not asphaltic or reinforced steel must be removed. It is important that the surface be clean and level. To remove any excess spray, a stiff bristle brush is used.
After the surface is prepared for use, the contractor must provide all of the necessary equipment, labor and materials. The contractor must also have sufficient shotcrete to meet project specifications. To transport materials to the location, contractors will normally use a ready-mix truck. Depending on the type of project, other equipment may be required.
A contractor will need to use many different methods to prepare a surface in shotcrete. Abrasive blast cleaning is a good option. High pressure water blasting and chipping Hammering are also options.
The shotcrete can be used on top or in place of any existing structure. However, the surface must be protected from drying right away after it has been applied. Install a layer with impervious material to protect the surface. It should be trimmed approximately 45 degrees from your work surface.
Once the surface is prepared the shotcrete gun should be pointed perpendicularly at the working face. Unless otherwise specified, the shotcrete shall be applied from the lower portion of the area upward. You may occasionally need to add layers of shotcrete to repair portions of the job that are not as thick.
The shotcrete must adhere to surfaces without flowing and should have a rich, glossy look. The consistency of the shotcrete can be controlled by adding pozzolanic material to the mixture. The proportion of water to be added to the mixture should also be controlled.
Before installing shotcrete the contractor will need to conduct a series of tests. Each panel must measure 3 1/2 in thick and include 2-#4 bars. The testing panels should be done by qualified personnel. They should also provide all the materials required for the project and conduct the coring. Upon approval of the test panel by the Engineer, the shotcrete contractor will be able to proceed with the substructure repair.
The Engineer must be notified by contractors before they apply shotcrete. This will enable the Engineer inspect the work and make a decision about whether it is satisfactory. Any repairs that are not acceptable may be halted.
The contractor must also ensure that the surface is uniformly distributed from batch to batch. A shotcrete that is either too thin or too thick won't be able resist the stresses encountered during construction. Moreover, it is important to keep the temperature of the shotcrete below 90 degrees Fahrenheit.
