Known for its dependable structural strength, gunite is a concrete blend of sand, cement, and water that’s applied through a high-pressure hose. Once it cures (dries), gunite becomes rock hard, forming a thick, solid structure.
Is gunite stronger than shotcrete?
Durability. Gunite generally lasts longer and maintains a higher quality than shotcrete. For instance, gunite tends to dry faster than shotcrete, leading to a much smoother surface and avoiding significant cracks from shrinking. Gunite can also withstand up to 9500 psi, a much higher psi than shotcrete.

What are shotcrete walls?
A shotcrete wall is constructed by using a special mix of high-strength concrete, which is sprayed at high velocity on the wall using compressed air, to form a retaining structure, drain, or wall. shotcrete walls provide a permanent and cost-effective solution for retaining wall construction.
