High Traffic Commercial/Light Industrial applications including light manufacturing, warehouse/big-box stores and high traffic retail applications present their own unique challenges in concrete repair. This presentation will review concrete repair options that a focused on those application that may require both fast application/turnaround time and strength/use durability for forklifts and trucks. High Traffic Commercial/Light Industrial applications including light manufacturing, warehouse/big-box stores and high traffic retail applications present their own unique challenges in concrete repair. This presentation will review concrete repair options that a focused on those application that may require both fast application/turnaround time and strength/use durability for forklifts and trucks. While there are many option for quick repair that can be open to use in a matter of hours, it is important to acknowledge he potential limitations of these options over the long term.
Vertical/overhead repair mortars are traditionally hand- or spray-applied. Small repairs are suitable for hand application; whereas, low pressure spray equipment is useful for large projects. Mortar guns are commonly used for tuckpointing applications using site-mixed, masonry mortar. As most vertical/overhead concrete repair materials exhibit a stiff consistency, such mortar guns have not been widely implemented in concrete repair applications. With its unique, thixotropic rheology, MasterEmaco N 425 is well suited for use with such equipment. This demonstration presents the ease of application of MasterEmaco N 425 using a Quikpoint 3000 mortar gun.
What happens when a building owner calls with leaks into a building they just finished? After verifying whether they want to file a lawsuit or not, the course of action is important. An investigation and preliminary testing are typically recommended to understand the original design and the quality and consistency of the construction. Design of remedial repairs and a pilot repair program followed by retesting to confirm results. How extensive are the failures and how invasive do the repairs need to be? Costs? What materials were used and were they compatible? Public perception and developer/owner reputation are important. The occupants have just moved in. Higher expectation of successful repairs. Can we involve the original design and construction team? These are just a few of the issues that need to be faced early in this process. One must communicate often and clearly with the owner and rest of the project team in order to manage expectations, costs and construction quality control.
Dallas City Hall and Plaza are recognized by many due to the opening scenes of Dallas, the television show. What is less known is that the structure is a significant early example of bonded post-tensioned concrete which was utilized throughout the superstructure and two-story parking garage constructed beneath the plaza. Opened in 1977, the parking garage is a two-way bonded post-tensioned concrete slab with unreinforced drop panels supported by flared circular concrete columns. The garage covers two city blocks, extends under two adjacent multi-lane streets, and supports mature landscaping, pool, fountain, and up to 11’-0” of soil. In 2017, several square feet of a drop panel fell from the structure and subsequent observations found multiple locations of drop panel and column capital failures. A structural investigation including destructive and non-destructive testing, and analysis of the existing structure was undertaken to determine the cause of the failures.
As long as there is concrete there will be concrete cracks. There is no shortage of repair methods for cracked concrete but the challenge is to find the right one that meets your specific needs. This product demonstration will cover polyurethane injection for leak mitigation. The area of focus will be understanding why concrete cracks, when to use polyurethane or epoxy injection, safety and equipment required for injection work, and lastly, the injection process itself.
The demonstration will cover the basic steps, products, and processes involved with dying and polishing concrete. The equipment, tooling, chemicals, and processes used to achieve a polished floor will be demonstrated.
This demonstration will take the audience through the entire process involved in the safe and effective installation of our GeoTree RenewWrap CFRP product.
This demonstration will show FastPatch DPR, an easy to install, long-lasting repair material for distressed pavement that can be applied in warm or cooler climates. It can be used with FastPatch Kicker (accelerator) to form a fast-curing permanent repair that is ready for traffic in a short period of time. DPR has excellent adhesion, absorbs impact and is freeze-thaw resistant. It can easily create smooth transitions and ultra-tough level surfaces. Its minimal site preparation and fast cure times reduce traffic interruptions. The product is completely odorless making it also suitable for indoor applications.
Industry experts Eric Muench and Dan Wald will discuss how to best select the right traffic bearing waterproof membrane technology for concrete protection.
