Modular Plants for Shotcrete & Backfill

Tecwill provides modular plants for mixing shotcrete, fibrecrete, backfill paste, CAF (cemented aggregate fill) and CRF (cemented rock fill) for underground tunneling and mining.

Tecwill shotcrete / fibercrete plant

Tecwill shotcrete solutions create significant savings in tunnel construction and mining operations:

  • Homogenous fiber dosing for polypropylene (PP), steel or synthetic fibers
  • Better shotcrete quality without fiber clumps, fewer problems with sprayers
  • Reduced cement content in a mix design by up to 15%
  • Lower CO2 emissions
  • Better tunnel lining quality with improved work safety
Benefits and savings

Why choose Tecwill shotcrete technology?

Fast weighing and fiber dosing control with Tecwill’s “flying” weighing system.

  • More accurate weighing
  • Less cement
  • Correct slump

Multipurpose hybrid plant.
No need for a separate shotcrete plant, as the same unit can mix all mix designs.

The same plant can mix:

  • Shotcrete with all types of fibers
  • Ready-mix concrete
  • Grout mix
  • CAF or Backfill, if the necessary equipment is included in delivery
  • Precast concrete

Modular construction making the concrete plant fast to install, even in winter, and easy to relocate and reinstall year-round.

Tecwill preassembles the complete concrete plant at its own factory. This includes pre-wiring, piping, thermal insulation enclosure and plant testing.

  • Fast set-up time, even in winter
  • Easy to relocate and reinstall year-round
  • Reliable winter operations

Tecwill’s high-precision “flying” weighing system saves cement and reduces CO2 emissions. 

Tecwill-flying-weighing-system-conveyor_1-1

Our “flying” aggregate weighing system eliminates the need to add extra cement to the mix design to compensate for inaccurate weighing and dosing.

  • More accurate weighing
  • Less cement
  • Correct slump

Modular construction makes the plant fast to install, even in winter, and easy and safe to operate.

  • Fast set-up time, even in winter
  • Easy to relocate and reinstall
    year-round
  • Reliable winter operations

A multipurpose plant capable of mixing CRF and CAF backfill, fiber shotcrete, and ready-mix concrete.

You don’t need a separate plant for backfill, the same production unit can handle all mix designs:

  • Ready-mix concrete (RMC)
  • Shotcrete with fibers
  • CAF backfill (cemented aggregate fill)
  • CRF backfill (cemented rock fill)
