This session will describe the use of tensile pull-off (bond) testing for concrete repairs and bonded overlays. It will provide guidance on applications of the test, industry standards and guidelines, acceptance criteria, proper testing procedures, appropriate equipment, and interpretation and reporting of test results. Bond is important because it relates to structural requirements (e.g. for strengthening and structural repairs) and for durability requirements (e.g. for overlays and cosmetic repairs). Testing of bond is needed to verify that the specified bond requirements have been met and a satisfactory result has been obtained.
Moisture accumulation and water leakage into retail, commercial, and residential habitable spaces, including industrial facilities and below-grade parking structures, is the number one construction defect claim in our industry. The entire building envelope is a moisture barrier. Below-grade moisture barriers are required to keep water from leaking “into” and/or “out from” the structure. Water leakage inflow or outflow, and moisture accumulation within, can lead to health, safety and environmental issues involving the cost of operations and facility maintenance. Active water leakage, intermittent wetness, cavity wall moisture accumulation, and vapor transmission, can lead to costly problems: mold and mildew development, corrosion, contaminated water clean-up and disposal, slippery surfaces, and property damage.
This demonstration covers MiraGard Granite, a water-based dual component, self-crosslinking acrylic resin binder specifically designed for use as a decorative vinyl flake broadcast system to simulate the depth and texture of natural granite stone. The product is moisture vapor permeable and can be used as a beautiful decorative topcoat over new concrete or existing concrete needing repairs whether exterior, interior, slabs-on-grade or elevated slabs. It is also rapid curing and can be completed in one day with fast return to service typically in as little as only 24 hours, and offers outstanding durability and wear resistance, UV stable for superior color retention and weathering resistance, good resistance to moisture absorption, environmentally friendly and VOC compliant and water-based for easy clean-up.
This presentation will look at how technology is used to perform condition assessments at height and in places with difficult access utilizing a virtual toolbox that includes a wide range of instruments and tools for non-destructive evaluation and testing, and a fleet of drones, each of which has a different use. The presentation will discuss how to use drones and tools at height; how the industry is using drones in new ways; and how some municipalities are changing policies to adapt, especially with regard to facade inspections.
This demonstration will show the repair of cracks in concrete using structural polyurethane injection without pumps, ports or cutting, featuring Roadware 10 Minute Concrete Mender and Easy Injection System. This no cutting method generates almost no dust making silica dust mitigation much easier.

Grout-filled socks combined with threaded bars are gaining popularity to form a strong chemical and mechanical bond for securing external walls to hollow concrete floor slabs, for stitching cracked solid and multi-lead walls, for stabilizing rubble-filled walls, and securing unstable parapet walls and arches. This technology is ideal where high levels of performance are required in bending for heavy duty, high load applications. The demonstration session will provide an overview of this fast, efficient, proven installation technique.
