Thin Spray Liners

Elastic polymer-based thin spray-on liner (TSL) for surface reinforcement and weathering protection of soil, rock and coal strata

• Water- and air-tight

• For preventive measures on ventilation and seals

• Protects from atmosphere deterioration

• Product expands and flexes with roof or rib changes

• Unique waterproof membranes 

• Prevents weathering in newly mined entries

• Sprayed on white for a brighter reflection

• Approved for ventilation controls

• Fireproof and can be used in charging stations 

• One-component polymer powder, applied with baby reed pump

• Dry spray application, mixed with water in the spraying nozzle 

• Sets within 5-10 minutes; generates tensile strength over the next hours, days, months

• Good bond and high elasticity

• Application thickness of 2-10 mm, average 4 mm

• No toxic components and virtually dust free, enhancing mine health and safety

​

Fast

• Can be applied at one square foot per second

• Rapid set-up; allows stop and start at any time

• Only needs compressed air

 

Safe

• Improves visibility in mine due to white color 

• Neither methane nor radon can pass through it

• Improves ventilation by creating smooth surface to the strata

• Impermeable

 

Maintenance

• Easily washed and readily accepts rock dust

• Will stop the symptoms of weathering and prevent small rocks from falling

• Will not corrode. Forty-year life expectancy

• Not affected by Mine Acid Water

 

Cost Effective

• No rebound or waste of material

• Takes less man power and cost to spray five times more than gunite or shotcrete

• One pallet of TSL can replace 14 pallets of shotcrete or gunite to do same area

• Requires a small, low cost machine that is permissible to use anywhere in the mine (Baby Reed SOVA, Allentown, Blastcrete Picolla or equivalent)
