© 2013 Armtec Infrastructure Inc. • Confidential & Proprietary
TRENCHLESS CONCEPTS
• Trenchless construction is a subsurface installation that does not require open cut excavation
• Trenchless technology can be used for:
1. New construction (tunneling)
2. Rehabilitation (relining)
TRENCHLESS BY ARMTEC

TRENCHLESS CONCEPTS
• Trenchless technology is a growing industry due to the many benefits vs. open-cut excavations
• Aging infrastructure is also putting a demand on replacement and rehabilitation of existing structures
• More than half of Canada’s infrastructure is 40+ yrs. old
• Almost a third of Canada’s municipal water infrastructure is approaching its service life

Trenchless
• Minimal to no traffic or business disruption
• Reduced impact to local environment
• Excavation & hauling material not required
• Minor to no impact to road surface
• Worker safety improved
• Trenchless is green
TRENCHLESS CONCEPTS
Open Cut
• Reduced or re-routed traffic; disruption to local business
• Impact to local environment (dust, silt, other contamination)
• Potentially high cost of excavation, hauling
• Disturbed road surface affects pavement quality
• Worker safety at greater risk

TRENCHLESS CONCEPTS
Trenchless is Green
TRENCHLESS BY ARMTEC
• Trenchless eliminates the need of running excavation equipment
• Trenchless eliminates the need for moving and hauling excavated material
• Overall reduction in equipment/vehicle emissions

TRENCHLESS CONCEPTS
Tunneling
• Tunneling is a subsurface excavation commonly used for new construction in mining & infrastructure applications
• Tunnels can be constructed using a wide variety of trenchless technologies including:
• Steel liners• Precast liners• Sprayed concrete (shotcrete)• Pipe jacking
TRENCHLESS BY ARMTEC
16
© 2013 Armtec Infrastructure Inc. • Confidential & Proprietary
TRENCHLESS CONCEPTS
Tunneling
• Tunneling typically involves a staged excavation & installation process:
1. Excavate tunnel as allowed per soil conditions
2. Install rings of liner
3. Pump grout between liner and excavated tunnel
Voids must be filled to perform as a structural liner
4. Repeat steps
• Geotechnical or tunneling engineer is required• Contractor experienced in tunneling is recommended

TRENCHLESS CONCEPTS
Relining
• Relining is the installation of a new surface to an existing structure to provide either a facial or structural restoration
• Aging tunnels or culverts experiencing cracking, spalling, or corrosion may require a new surface to prevent further deterioration
• Deteriorated structures in danger of failing may require a fully structural reline
TRENCHLESS BY ARMTEC
20
© 2013 Armtec Infrastructure Inc. • Confidential & Proprietary
TRENCHLESS CONCEPTS
Relining
• Culvert relines typically involve a sliplining process:
1. Slide coupled or pre-assembled pipe liner into the existing pipe
2. Utilize bracing or blocking to hold structure into place
3. Pump grout between new and existing structure
Voids must be filled to perform as a structural liner
• Flanged liner plates can be assembled in place*
