Repair Application Procedures and Case Studies, Part 1 of 2
Tuesday, October 28, 2025 1:30 PM - 3:30 PM, H - Holiday 3
This is the first of two sessions provided by the ACI E706 Concrete Repair Education Committee. The first session will cover Concrete Repair Application Procedures (RAP) 1-8 and associated case studies. Anyone interested in concrete repair techniques and case studies would benefit from this session. The thesis behind this session is to learn basic concrete repair procedures and gain knowledge in concrete repair from industry practitioners. Understand step by step concrete repair techniques and safety considerations.Learning Objectives:(1) One of the most effective ways to address cracks in concrete is to inject epoxy under pressure into the cracks. The injection procedure varies depending on whether the crack is horizontal, vertical or overhead. Learn different approaches to pumping epoxy into cracks under pressure;(2) For horizontal cracks that are not moving (shrinkage and settlement cracks that have stabilized), gravity feeding of epoxy is a good methodology for sealing the cracks to keep out moisture, chlorides, sulfates, etc.;(3) Low velocity spray is typically used for vertical and overhead repairs in tight spaces or where the surface area is large enough to increase productivity versus hand patching;(4) Form and pour and form and pump are two techniques available to accomplish surface repair. Benefits include the use of multiple repair materials, encapsulation of reinforcing steel and formwork to minimize early age shrinkage of repair materials. Form and pump is a good solution with congested reinforcing situations and thicker repair thickness requirements.This session has been approved by AIA and ICC for 2 PDHs (0.2 CEUs). Please note: You must attend the live session for the entire duration to receive credit. On-demand sessions do not qualify for PDH/CEU credit.
Structural Crack Repair by Epoxy Injection Presented By: Benjamin Estrich Affiliation: Martinmartin Inc Description: One of the most effective ways to address cracks in concrete is to inject epoxy under pressure into the cracks. The injection procedure varies depending on whether the crack is horizontal, vertical or overhead. RAP 1 describes different approaches to pumping epoxy into cracks under pressure.
Crack Repair by Gravity Feed with Resin Presented By: Etien Frett Affiliation: Euclid Chemical Description: For horizontal cracks that are not moving (shrinkage and settlement cracks that have stabilized), gravity feeding of epoxy is a good methodology for sealing the cracks to keep out moisture, chlorides, sulfates, etc.
Concrete Repair by Low-Velocity Spraying Presented By: Etien Frett Affiliation: Euclid Chemical Description: Low velocity spray is typically used for vertical and overhead repairs in tight spaces or where the surface area is large enough to increase productivity versus hand patching.
Surface Repair Using Form and Pour and Form and Pump Techniques Presented By: Peter Emmons Affiliation: Structural Technologies Description: Form and pour and form and pump are two techniques available to accomplish surface repair. Benefits include the use of multiple repair materials, encapsulation of reinforcing steel and formwork to minimize early age shrinkage of repair materials. Form and pump is a good solution with congested reinforcing situations and thicker repair thickness requirements.
Vertical and Overhead Spall Repair by Hand Application Presented By: Peter Emmons Affiliation: Structural Technologies Description: One of the most common application methods for repairing concrete is by hand troweling mortars to replace damaged concrete. These methods are ideal for shallow surface repairs with limited or difficult access. Selection of sag-resistant mortar, application techniques, curing methods and properties of repair material are critical.
Installation of Embedded Galvanic Anodes Presented By: David Whitmore Affiliation: Vector Corrosion Technologies Ltd. Description: Embedded galvanic anodes are attached to reinforcing steel within the repair cavity to minimize corrosion of reinforcing steel adjacent to the repair. Embedded galvanic anodes are available in a range of sizes and design. Selection of type and size are important considerations.
