Sika Aliva long lasting quality

Aliva® shotcrete equipment is used in tunnels all over the globe. 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.

Rotor Machines

By conveying through a rotor the material is transported with pressurized air by the thin stream process to the spray nozzle, where it is mixed with water and any additives (e.g. accelerators) can be added. These Aliva® machines have sealing plates made from special steel and an automatic lubrication system that reduces wear and tear, and therefore also downtime and operational costs.
