WHY A SILO MANUFACTURER WOULD LIKE TO INTRODUCE YOU TO GUNNITE (SHOTCRETE) ?

When travelling through countryside you can see from time to time a silo "dripping".The liquid coming out the wall of that structure is silage acids that deteriorates concrete and steel.That liquid is produced when the moisture content of the ensiled material is too high for the size of the silo (the bigger the silo, the lower the moisture content of the material to be respected to avoid seepage). The rate and severity of the degradation of the concrete wall will depend on different factors, one of, which is the frequency at which the silo was filled with too moist silage. Restoration of silo walls with gunnite is the stronger, safer, long lasting and economical way to repair and save your initial investment.

 

DEFINITION OF GUNNITE:

"Gunnite is a process where concrete is projected under pressure onto a surface to form structural shapes such as walls and roofs"-PCA

 

GUNNITE VS CONVENTIONAL CONCRETE:

Conventional concrete is placed first and than vibrated; while gunnite is placed and compacted at the same time. This is a possible due to the tremendous force with which it is projected from the machine. Because of this process the end product offers better quality such as higher density, reduced permeability, increased compressive strenght and resistance to chemical attacks. With the proper preparation of the surface to be repaired and the force of application of the product, the bond between the surfaces is higher than the material of the old surface.

The use of Gunnite has been widely spread of successfull restorations of old silo walls for over 25 years.Thus, gunnite is an efficient solution to a real problem.

 

OTHER USE OF GUNNITE:

Gunnite is used to restored bridges, water dams, overhead parking garages, tanks, pools, tunelling...
