Gunite Machines, Accessories and Spares (for dry spray Shotcrete)
Gunite Machines are widely used in the Refractory industry where the sand, cement and aggregates are replaced with refractory materials and then sprayed.
Our range of sprayed concrete machines covers a wide range of applications from low value refractory applications to high volume civil construction.

Gunite is a trade term for dry-mix Shotcrete (or dry spray Shotcrete). The dry mix method involves placing the dry ingredients into a hopper and then conveying them pneumatically through a hose to the nozzle. The nozzleman controls the addition of water at the nozzle. The water and the dry mixture is not completely mixed, but is completed as the mixture hits the receiving surface. This requires a skilled nozzleman, especially in the case of thick or heavily reinforced sections. Advantages of the dry mix process are that the water content can be adjusted instantaneously by the nozzleman, allowing more effective placement in overhead and vertical applications without using accelerators. The dry mix process is useful in repair applications when it is necessary to stop frequently, as the dry material is easily discharged from the hose.
Typical applications are such as: swimming pools, refractory installation, furnace spraying, repair for bridges, walls, columns, beams, slabs, sewers, channels, piers and Gunite seawalls, Sand & gravel backfill, Civil & Infrastructure Projects, Mines, Tunnel Lining, Bank or Slope Stabilization.
