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.
TABLE OF CONTENTS
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
Why choose Tecwill shotcrete technology?
Fast weighing and fiber dosing control with Tecwill’s “flying” weighing system.
Shotcrete mixing with Tecwill’s innovative on-conveyor fiber feed that reduces mixing time and fiber clumps.
- 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

Why Choose Tecwill CAF / CRF Backfill Technology — How We’re Different

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

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.

Tecwill’s approach is to preassemble the complete plant at its own factory. This includes the 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
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)
