Concrete is one of the most versatile building materials in the world and can produce floor slabs that provide an excellent platform for floor coverings and coatings. Water is an essential component of every concrete mixture. Without it, concrete is not workable and finishable. If water is not used, the cement in the mixture cannot hydrate and gain the required strength. However, once placement, finishing, and curing is complete, remaining moisture in the concrete can adversely affect the installation of flooring materials and the behavior of the slab itself. This webinar will discuss the importance of water in a concrete mixture and review a few concrete problems that water can cause, such as shrinkage, curling, ASR, delamination, dusting, and scaling. In addition, attendees will learn the design and construction considerations that can be used to minimize the potentially adverse effects of moisture in concrete.
Moisture coming from, or through a concrete floor slab, can lead to conditions that are damaging to floor coverings, coatings, the building’s environment, and the ability to store moisture sensitive products directly on a floor slab. In this webinar, attendees will learn where potentially damaging levels of moisture come from, how moisture migrates, and what design measures are an absolute necessity to minimize the risk of moisture-related problems.
Moisture-related problems with floor coverings and coatings are a serious and costly issue. Each year the direct and in-direct costs associated with such problems amount to billions of unplanned dollars. In this 5-part webinar series, experts in the field of moisture in concrete, testing, mitigation and repair will share information and experience in a ground up approach to the causes and solutions to such problems. The program covers the sources of moisture in concrete, the affect moisture has on slab behavior and the installation of flooring materials, the test methods used to properly assess slab moisture condition, moisture mitigation strategies, and more.
ACI and ICRI have published an updated “Guide to the Code for Assessment, Repair, and Rehabilitation of Existing Concrete Structures, A Companion to ACI 562-19.” This guide provides the licensed design professional with the knowledge, skill, and judgment to interpret and properly use ACI 562-19, and provides insight into the use and benefits of the code for contractors, material manufacturers, building owners, and building officials.

This latest version of the code was developed to provide design professionals a code for the assessment of damage and deterioration, and the design of appropriate repair and rehabilitation strategies. The code provides minimum requirements for assessment, repair, and rehabilitation of existing structural concrete buildings, members, systems and, where applicable, nonbuilding structures. ACI 562-21 was specifically developed to be incorporated into the International Existing Building Code (IEBC) or to be adopted as a stand-alone code.
This bundle includes the 110.1 (2016), 110.2 (2020), 110.3 (2021). 330.2 (2016) Guide Specifications.

The demonstration will cover the use of MAPEI’s high alkaline corrosion inhibitor, Mapefer 1K and encapsulation of the repair area with Planitop 12 SR. Planitop 12 SR is a versatile, sulfate resistant, fiber-reinforced, with silica fume and corrosion inhibitor that can be applied by hand, pump, or spray on horizontal and vertical surfaces. Demonstration will show how to utilize these products in accordance with ACI Repair Application Procedures (RAP) 3, 6, and 7 as well as ICRI Guideline Nos. 310.1R and 310.2R. Demonstration will showcase a project where Planitop 12 SR was recently used to repair a Wastewater Treatment Tank.
After only six years of service, a 6-foot long narrow piece of concrete spalled off an exposed slab edge of a 680-foot tall high-rise in Texas, and fell 160 feet to the podium below. The spall was attributed to premature corrosion at the drip edge. The building featured approximately 9,200 feet of exposed slab edge over its height. Given the potential risk to safety and property of additional concrete spalls, the Owner requested forensic investigations, which (1) identified other areas with signs of similar distress and (2) determined the underlying problem of low reinforcement cover at the drip edge was pervasive. In response, repair options were developed to address the problem and restore intended durability. Given the building height, difficult exterior-only access, downtown environment, and post-tensioning anchors along the slab edge, the repair design and construction both had unique challenges to consider and overcome.
