Allen Face & Associates > Concrete Floor Seminars

• Make the common concrete floor dispute a thing of the past

• Design floors that meet everyone's expectations every time!

• Install floors that routinely satisfy even the most demanding customers

• Understand the F-Number System like an expert

• Hear the final word on cracking, curling, slump, vapor retarders, mesh, joints, base preparations, surface treatments, and the whole host of other issues critical to concrete floor performance

"State-of-the-Art Concrete Floor Design, Construction, and Quality Control"

Allen Face is the author of the F-Number System (ASTM E-1155) and is one of the world’s leading authoriities on slab-on-grade design, construction, and quality control. Inventor of the Face Floor Profilograph, the Dipstick® Floor Profiler, the F-Meter®, and the D-Meter®, he helped pioneer the design and construction methodology for superflat floors, and developed the F-min Equations now used to set the wheel track tolerances for all narrow-aisle lift trucks.

During his 30-year career in high performance concrete floor construction, he has overseen the installation of more than a thousand individual superflat slab placements and has trained hundreds of flatwork contractors worldwide in advanced placing and finishing techniques. Between 1986 and 1992, he presented dozens of day-long seminars around the country on state-of-the-art slab-on-grade design, construction, and quality control. His consulting practice continues to take him to major flooring projects and floor-related disputes throughout North America.

Mr. Face is a long-time member of ACI committees 302 (Floor Construction), 360 (Slab-on-Grade Design), and 117 (Tolerances). He authored the new sections on superflat floors and surface profile control in ACI-302.1R-89, the landmark floor tolerance revisions to ACI-117-90, and the forward to the current ACI-302. He is an ACI Fellow, and in 1990 was the very first recipient of the Construction Innovation Forum’s prestigious Nova Award for Outstanding Contributions to American Construction Technology.

Seminar Program

First, you’ll have to put aside what you think you know about concrete floors and open yourself up to a whole new way of looking at slab-on-grade optimization. In this free-form, give-and-take seminar, Allen Face will discuss slab failure modes, the current physical model, critical concrete characteristics and their control, sub-grade, base, and vapor retarder considerations, slab thickness determination, shrinkage and curling, dead and live load crack induction mechanisms, joint connection details, the proper function of reinforcement, and a host of other topics all aimed at keeping your future concrete floor installation projects out of trouble.

8:00 - 8:15
