What is tunnel rehabilitation:

Concrete linings of existing tunnels may suffer from related damage due to aging or weathering or improper construction techniques thus a certain level of tunnel rehabilitation is required.

Our Accomplishments:

• Since 1990s, SCG has developed significant tunnel rehabilitation technologies
• Machine sliplining and manual slipliing were conducted in tunnels as small as 600mm ID, even in live sewers
• In the past 10 years, SCG has completed around 30 tunnel rehabilitation projects
• The total combined length of rehabilitated tunnel is over 45 km
