Renovation of Slabs on Grade
Instructor Information: Alexander Newman, P.E., F.ASCE
Course Length: 2 Hours
This webinar was co-sponsored by ASCE's Structural Engineering Institute and ASCE Continuing Education
Purpose and Background
Slabs on grade are among the few structural elements that are exposed to the owner’s eye. It is only natural that any defect or perceived problem tends to be noticed and brought to the engineer’s attention. However, many problems in floors on ground are related to concrete and soil performance rather than design, and repairing them is not always easy.
The webinar provides an overview of typical problems in slabs on grade, such as settlement or heave, damage caused by environmental factors, structural failure, cracking, curling, joint deterioration, and delaminating finishes. For each problem, the instructor outlines the effective yet economical methods of detection and renovation. In some cases, slab replacement is the best option, and the webinar covers proven design details for this task.
- Examine problems of slabs on grade and methods of their repair
- Discuss practical methods of renovating settled and heaved slabs
- Learn to identify various kinds of slab cracks and surface defects and the best ways of repairing them
- Explore the issue of slab repair vs. replacement or overlay
Structural and civil engineers, architects, facility managers, and building officials seeking to broaden their knowledge of renovating slabs on grade will benefit from this webinar. There are no calculations involved, and those who are not engineers will not be overwhelmed, because the instruction is kept enjoyable, practical, and easy to follow.
