What is Gunite? (Pools & Walls)

Gunite is dry-mix concrete sprayed through a hose and wetted at the nozzle. The high-velocity compaction creates dense, strong concrete. It's used for vertical pool walls and other applications where traditional pouring isn't practical. Understanding gunite helps you understand specialized concrete applications.

What is Gunite?

Gunite is:

Dry-mix concrete: Cement and aggregate mixed dry
Sprayed through hose: Pneumatically sprayed
Wetted at nozzle: Water added at spray nozzle
High velocity: Sprayed at high speed

How It Works

The gunite process:

Dry mix: Cement and aggregate mixed dry
Sprayed through hose: Pneumatically conveyed through hose
Water added at nozzle: Water introduced at spray nozzle
High velocity impact: Hits surface at high speed
Compacts on impact: Velocity creates compaction

Why High Velocity Compaction Matters

The high velocity creates benefits:

Dense concrete: Impact compacts concrete densely
Strong bond: Bonds well to surfaces
No forms needed: Can build vertical walls without forms
Versatile application: Can spray on any surface

Common Uses

Gunite is used for:

Pool walls: Vertical pool walls and structures
Retaining walls: Vertical walls where forms are difficult
Repairs: Patching and repairs
Curved surfaces: Where forms aren't practical

Gunite vs Traditional Pouring

Gunite Advantages:

No forms needed
Works on vertical surfaces
High compaction
Versatile application

The Bottom Line

Gunite is dry-mix concrete sprayed through a hose and wetted at the nozzle. The high-velocity compaction creates dense, strong concrete. It's used for vertical pool walls and other applications where traditional pouring isn't practical. Gunite's ability to be sprayed without forms makes it ideal for pools, walls, and curved surfaces where traditional concrete placement isn't feasible.
