From the deep Canadian cut and fill operations to narrow epithermal shrinkage operations in Mexico and Asia, Aliva equipment is reliable wherever and whenever you need it. The equipment is especially designed for operations where access is difficult and small, equipment is of use due to smaller drift diameters. The equipment can be used for dry and wet spraying.
Assembled According to Your Needs
Due to the modular set-up of the Aliva spray systems, the spray rigs can be customized according your needs. The «carrier independent system» or «CIS» allows to combine the different modules based on the needed output volume, the carrier of choice and the accessibility of the sprayed areas.
Yielding Underground Support with Sika Fiber 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 Fibers are high quality, macro-synthetic fibers used in underground projects around the globe and proven to outperform steel-fibers when it comes to energy absorption and cost-performance of the shotcrete support.
Sika Fiber Force
Sika® Fiber Force is the macro-synthetic fiber product range from Sika. The Sika fibers provide excellent yielding characteristics within the shotcrete liner or specific concrete structures such as slabs and piles. The fibers can be sourced in different packaging options including handy fiber-packs that easily dissolve in the wet concrete mix.
Optimize Your Shotcrete Mix
Macro-synthetic polypropylene fibers have become the standard in many mining operations around the globe. Macro-synthetic fibers have a few key advantages compared to steel fibers including avoidance of corrosion, much lower dosage (on a per weight basis), much better yielding characteristics, easier handling and better overall price performance.
3. Mine Paste Backfill Admixtures
Admixtures to Optimize Paste Backfill Operations
Sika offers a wide range of mine paste backfill admixtures that can be dosed directly into the wetted out mix of the paste plant. The admixtures are based on the proven Sika PCE technology and can have a dramatic effect on the rheological behavior of the paste. The admixtures act as a high range water reducer and therefore provide the opportunity to significantly reduce the cement consumption of the paste operation. Sika is in position to provide extensive on site support and to support you with the right paste backfill design.
Optimize Your Mix
Sika applies similar principles that we use in concrete also for mine paste backfill plants worldwide using our chemical toolbox that has been refined over the past decades. We can help you to achieve the following with your backfill paste:
- Reduce binder consumption
- Improve compressive strength
- Reduce bleeding
- Facilitate paste pumping
- Reduce wear and tear of machinery and paste lines
- Speed up mine and fill cycle time
Customized Solutions
Every mine paste is different in terms of its granulometry, the chemical composition and the binder types used. Sika is experienced in analysing the different pastes in order to find the admixtures that will suit your paste best. By doing so, we are in position to deliver the competitive edge when it comes to cost reduction and mix optimization.

10. Dust Sealers
Don’t Get Lost in the Dust
In most mining environments, dust represents one of the highest health and safety concerns no matter if the operation is located under- or above ground. Therefore, a lot of effort is put into reducing dust generation to an acceptable level, on a daily basis. Sika Dust Seal®-300 is a new product from Sika, that prevents dust particles going airborne and reduces dust generation over an extended time period. The product is fully bio-degradable and is diluted with water prior to application.
Dust
Dust generates all sort of problems, ranging from health and safety concerns due to reduced visibility and respiration issues to increased wear and tear of machinery and equipment and increased ventilation costs in underground workings. Sika Dust Seal-300 is designed to provide a safe, water based and environmental friendly alternative to current dust-sealing solutions.
Easy Application
The Sika Dust Seal-300 is currently supplied as a concentrated liquid solution that can be diluted with water in order to be applied on underground and open pit ramps drifts, haul roads, strips, dumps and stockpiles. The product forms a crust-like sealing layer with the dust particles that will last for an extended period of time. Watering efforts can be reduced strongly.
