Preventing Problems with Slabs on Ground: Thickness, Moisture, and Sulfates
Hosted by World of Concrete 360 and American Society of Concrete Contractors.
Sponsored by Allen Engineering, Euclid Chemical, Somero Enterprises, and Stego Industries.
What are the characteristics of a concrete slab that can get a contractor in trouble? Some of the most common answers include variations in thickness, excess moisture, and high sulfate soils. At this session, industry experts will discuss solutions to these and other issues with slabs on ground.
- What are reasonable tolerances for slab thickness for various types of slabs and how can they be met?
- Should tolerances for hard-troweled flat slabs be different than tolerances for sloped and broomed slabs?
- How can slab internal moisture levels be achieved within the expected time?
- What are the options if moisture remains too high?
- What is the effect of using vapor barriers on moisture?
- Are vapor barriers sufficient to protect a slab from high sulfate soils or must you attempt to place very low water-cement ratio concrete and find a supplier of Type V cement?
Attendees will hear how industry experts respond to these challenging questions – limited seating during this open forum – bring your questions for panelists Eldon Tipping, Principal with Structural Services Inc, Peter Craig, President of Concrete Constructives, and Scott Tarr, President of North S.Tarr Concrete Consulting.
