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.
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.
Testing moisture in concrete doesn't need to be complicated. Five (5) currently recognized ASTM test protocols for testing concrete slabs for moisture will be explained using the "How and Why" perspective while providing the proper, yet basic, scientific context behind their usage.
Moisture-related floor covering and coating failures are a very costly and disruptive issue with the direct and in-direct costs associated with such issues estimated to be in the hundreds of millions of dollars each year in the United States alone. In this session, a brief overview of the previous sessions will be provided and experts in the field of slab moisture, concrete, testing and forensics will answer your industry questions related to the subject.
The mitigation of moisture in concrete floor slabs has become an entire sub-industry to the placement of concrete floor slabs that will receive a moisture-sensitive floor covering or coating. In this webinar, attendees will learn what approaches are being used to mitigate an unacceptably high level of moisture in a concrete floor slab and what pre-installation evaluation procedures are necessary to help ensure the success of a moisture mitigation strategy.
Codes and standards are developed for use by design professionals; however, the use of codes and standards significantly impacts Owners and Contractors. The ACI 562 code was motivated by the poor performance of repaired concrete structures, specifically premature failure of repairs and limited durability of repaired structures. Development of the code was intended to benefit owners and contractors by improving performance and perceptions regarding repairs to existing structures.
This webinar will discuss the keys to proper surface preparation including establishing the appropriate level of surface profile, evaluating the concrete substrate and the material being installed to determine the correct level of preparation as well as the correct methods and tools to achieve that level.
Industry experts Eric Muench and Dan Wald will discuss how to best select the right traffic bearing waterproof membrane technology for concrete protection.
