What is GUNITE ?

A process in which cement and aggregate are mixed dry, then placed in a pressurised chamber that meters the material into a stream of compressed air that carries it to a nozzle where water is added under pressure through a perforated ring.

The water thoroughly wets the ingredients as the mixture is jetted from the nozzle at high velocity, and can be varied by operator to give very wet, to very dry concrete.

What is the advantage of GUNITE ?

In the manufacture of pre-cast units the greatest advantage (apart from superior strength of the concrete) lies in being able to finish the whole wall thickness in one operation, rather than having a number of layers, as in other methods of construction.

In tunnels, retaining walls etc a considerable thickness of concrete can be built with no fear
of slumping.

Why is GUNITE superior?

The strength of concrete or plaster depends on the water-cement ratio in the mix; the lower the amount of water required the greater compressive strength obtained.

Guniting requires only a fraction of the water required in concrete placed by others methods, and because it is applied with water under pressure of up to 100lbs per square inch which gives an extremely dense concrete.
