TEA TALK SEMINAR
“Waterproofing Technologies for Tunnel”
Wednesday 7th August 2019, 13:00-17:00 PM., at 4th Floor EIT Building
Organized by Thailand Underground and Tunnelling Group (TUTG)
The Engineering Institute of Thailand Under H.M. The King’s Patronage
Sponsored by Sika (Thailand) Limited.
Today, operators request a service life for underground structures of 100+ years, but a lack of water tightness severely reduces the long –term durability of a tunnel structure and badly affects its planned use, as water ingress results in physical attack and deterioration of the concrete. Expensive repair works, damage and operational downtime are the results. The selection of the appropriate waterproofing system and its safe application at site are the key elements to minimize the operation costs.
A waterproofing system typically amounts to a fraction of the total construction costs. The selection of a high quality waterproofing solution may easily save an amount of its initial investment or more on future maintenance and repair costs during the entire service life of the structure.
Objective: to define the appropriate waterproofing strategy and type of system for a specific project, it is important to consider not only the ground conditions but also the project requirements. Functionality and future use, the service life and the total cost of ownership
