Condition Assessment and Rehabilitation of Drainage Culverts, November 5


Date: November 5th

Location: Mississauga Grand, 35 Brunel Road, Mississauga.


The deterioration and collapse of drainage culverts has become a critical issue for municipalities and transportation agencies. Furthermore, many jurisdictions have experienced severe storms and increased flooding frequencies, an indication of climate change, in recent years. This causes serious damage to existing utilities, roads and public properties in addition to social and financial costs. The municipalities and transportation agencies have to spend millions of dollars on costly repair and reconstruction of damaged infrastructure. Consequently, liabilities and insurance premiums are increased. This workshop will demonstrate how trenchless technologies can provide efficient and economical tools and techniques for pro-active inspection, repair/rehabilitation, or replacement of existing drainage infrastructure.
