Soil Conditioning Takes a New Form

Encapso™ soil conditioner is a major step-change in the evolution of tunnel boring component delivery and is transforming the way operators fight sticking clays, water incursions and friction - resulting in superior boring efficiency and economics.

Innovative

• Increased advance rate by providing conditioning where it is needed most
• Wear reduction owing to the tribological properties of triglyceride oils
• Plasticizes spoils aiding muck removal
• Improves stability of tunnel face, by reducing water incursion
• Keeps ports open and clean when applied before shutdowns
• Compatibility with slurries and foams due to natural encapsulation

Proven Performance

• Seattle case study: 72% improvement in advance rate - 2X productivity
• Laboratory tests: less cutter wear – fewer interventions – faster progress

Proved benefits through commercial use in a 21-foot diameter tunnel:

• 72% improvement in advance rate after use in just 20 feet
• Made operations smoother by improving consistency of movement
• Improved productivity from 45 feet/day to 90 feet/day

Results

• Improved advance rate
• Improved consistency of movement
• Improved muck condition / consistency
