Epoxy Resin Injection
627.1DESCRIPTION
This section describes the requirements for furnishing and injecting epoxy resin for repairing cracks, delaminations, and voids in portland cement concrete.
627.2MATERIALS
1 Provide materials in accordance with the following:
Materials
Subsection
Epoxy Resin
810.6
627.3EQUIPMENT
1 Use a handgun or pressure pot for injection.
With the engineer’s approval, a machine capable of metering and mixing components to within 1 percent of specified properties and injecting resin may be used. Provide instruments to periodically check nozzle pressure.
627.4CONSTRUCTION
1 Work
in accordance with and give the engineer a copy of the epoxy resin manufacturer’s recommendations.
2 During injection, maintain a nozzle pressure of from 10 psi to 25 psi [70 kPa to 170
kPa]. 3 Clean repair surfaces of deposits detrimental to adhesion. 4 Alter void areas at the surface as necessary to allow installation of injection ports or tees.
Space ports or tees to completely and efficiently fill voids. Once in place, seal the void surface with a fast-setting cement paste mixture or epoxy mortar. 5 After the resin obtains its initial cure, remove ports, tees, and seal without marring
the concrete surface. Clean adjacent areas.
627.5MEASUREMENT and PAYMENT
1 The engineer will measure Epoxy Resin Injection as a complete unit, by the gallon
[liter], or by the foot [meter]. Measurement by the foot [meter] will be along the surface of the crack, delamination, or void.
