Yielding underground support with Sika fibre technology
Yielding primary Shotcrete liners have become the standard underground support in many mines around the globe. Increased stress levels in deeper mines require a yielding support in order to take up dynamic loads and seismic shocks from the rock mass. Sika fibres are high quality. Macrosynthetic fibres are used in underground projects around the globe and are proven to outperform steel fibres when it comes to energy absorption and cost-performance of the Shotcrete support.
SikaFiber® Force is the macrosynthetic fibre product range from Sika. The Sika fibres provide excellent yielding characteristics within the Shotcrete liner or specific concrete structures such as slabs and piles. The fibres can be sourced in different packaging options including handy fibre-packs that easily dissolve in the wet concrete mix.
Optimise your Shotcrete mix
Macrosynthetic polypropylene fibres have become the standard in many mining operations around the globe. Macrosynthetic fibres have a few key advantages compared to steel fibres, including avoidance of corrosion, much lower dosage (on a per weight basis), much better yielding characteristics, easier handling and better overall price performance.
