This guideline specification is provided to engineers, specifiers and architects to aid them in establishing the requirements for steel plate bonding by injection of structural epoxy adhesives. The specification also establishes the minimum requirements for such repairs by approved applicators of ChemCo Systems.
This specification establishes standards for materials and equipment, execution of work, field quality control, applicator and workman’s qualifications and provides information for measurement and payment. The procedures for work execution described herein are considered to be typical and may have to be modified for specific job conditions.
The Contractor or his sub-contractor, subject to certain pre-qualification conditions, shall furnish all materials, injection and auxiliary equipment, tools, labor and supervision necessary to fill voids on concrete substrate and perform other preparation for the injection of epoxy resin between the concrete and steel plate.
Surface Preparation, Placement of Injection Ports
Field Quality Control
Note: It is imperative that the location of tendons in structures be known and none are cut in the coring process.
Methods of Test Core Testing.
Test Evaluation and Acceptance.
The test equipment shall be a device with two independent sections, identical in design and function, one for each adhesive component, complete with proper fittings, pressure gauges (250 psi max. rating), in-line filters and needle valves with appropriate discharge nozzles. The device shall be capable of controlling flow rate and pressure of each adhesive component independently by opening or closing the needle valves.
