You will get knowledge about the epoxy injection method of crack repair in Boise Idaho, which is implemented by the various maintenance agencies. The epoxy injection process is one of the most efficient methods used for repairing the cracks. By this method, you can repair cracks as narrow as 0.002 inch. In this process, first of all; holes are drilled at close intervals along the cracks. In some cases, entry ports are installed and finally the epoxy is installed under pressure.
The equipments that are required for this process are a concrete drill, an epoxy injection system, tools for cleaning holes and cracks and normal hand tools. This method has been successfully used in the repair of cracks in buildings, bridges, dams and other concrete structures. Let’s take an overview of the step by step procedure that is undertaken in this method.
First of all, the cracks are cleaned. The cracks need to be cleaned from various types of contaminants such as oil, grease, dirt particles that prevent epoxy penetration and bonding. This cleaning step is performed by using an effective solvent. After that the surface cracks are sealed to keep the epoxy from leaking out. They are sealed by brushing an epoxy along the surface of the crack and after that it is allowed to harden.
The third step is installing the entry ports. There are three methods used for installing the entry ports. They are namely drilled holes, bonded flush fitting and interruption in seal. After that the epoxy is mixed and this is done by the batch or continuous methods. In the batch process, the adhesive components are premixed usually with the help of a mechanical stirrer. In the continuous mixing process, the two liquid adhesive components pass through the metering and driving pumps before passing through an automatic mixing head.
