ABOUT THE EVENT
New England has seen a growing epidemic of sidewalk and other exterior flatwork scaling, a condition that leaves concrete with surface deterioration ranging from localized pockmarks and blemishes to widespread near-surface loss of concrete. When scaling occurs, the resulting loss of concrete presents an aesthetic failure, a tripping hazard, and most importantly, a loss in confidence from users who see the damage as a project failure and a waste of time and money. With the causes of scaling well known, the continued and apparent increase in this type of failure is disappointing and somewhat mystifying. In this presentation, we will discuss the causes of concrete scaling using perspectives gained from working at the center of relationships between concrete producers, specifiers, owners, and cement finishers. The presenters postulate that this upsurge of scaling results from a self-reinforcing cycle of aggressive competition, pricing, actions, specifications, expectations, and supervision, in which all parties have some responsibility but cannot correct in isolation. We will also explore ideas for correcting this trend and mitigating its effects, including practical tips and case study examples.
After attending this seminar, participants will be able to:
- Understand the causes of surface scaling on concrete formwork.
- Recognize common mitigation strategies for avoiding concrete surface scaling.
- Identify factors leading to the recent onset of scaling issues, including aggressive competition, pricing, actions, specifications, expectations, and supervision.
- Discuss ideas for correcting and mitigating these effects.
