"Gunite", also known as "Dry-Process Shotcrete", is a name used to
designate a mixture of 1 part Portland Cement and 4 parts sand thoroughly mixed dry, passed
through a Gunite Machine, and conveyed by air through a rubber
gunite hose and deposited by air pressure. The large amount of air pressure serves to mix
and compact the mixture. The result is a smooth, hard surface.
Gunite bonds perfectly to prepared surfaces such as concrete, brick, rock, tile, stone or steel.
Numerous tests have been made which indicate that the bond strength of Gunite exceeds
the shearing strength of good quality brick or concrete against which it is applied.
Gunite is heat resistant to a high degree and can be made more
so by substituting refractory aggregates for part or all of the sand. Gunite is extremely
strong, dense, and highly resistant to weathering and many forms of chemical attack. Gunite
can be successfully applied to any desired thickness with uniform quality throughout.
Common "Gunite" Applications:
1. Swimming Pool Construction
2. Retaining Walls
3. Refractory Installation
4. Rockscaping
5. Artificial Rocks and Caves
6. Slope Stabilization
7. Concrete Repair / Rehabilitation of Concrete and Masonry structures (bridges, walls, columns, beams, slabs, sewers)
8. Backfill (sand & gravel)
9. Civil & Infrastructure Projects
10. Channels, Piers, Sea Walls
11. Mines
12. Tunnel Lining
13. Retaining & Fire Walls
14. Concrete Pipe
15. Fireproofing for steel structures
16. Ditches
