Silo Repair

In addition to sales of Kitchener Silo’s, we supply components, to repair all makes of stave or concrete silos. Distributors, filling pipes, ladders, safety cages, platforms, doors, and doorframe replacements are only a few of the standard repairs preformed by our trained installers. We offer a relining or restoration service using gunnite, suspension cable as well as tripod, or hexapod replacement services throughout Ontario.

Concrete Repairs

Rebuilding, restoration, stabilization of any concrete surfaces is accomplished using gunnite. Link to gunnite

ALL SILOS REQUIRE MAINTENANCE

-Foundation inspection
-Rod re- tensioning
-Attention to door, and step hardware
-Distributor
-Filling pipes, and brackets
-Interior wall surface

Inspection and replacement of these components when needed will insure ease of filling and excellent feed quality.

What is Gunnite?

Gunnite is “mortar conveyed through a hose and pneumatically projected at high velocity on to a surface”
*-ACI

Why is it different from conventional concrete?

Unlike conventional concrete, which is first placed and then compacted (vibrated) in a second operation, gunnite undergoes placement and compaction at the same time due to the force with which it is projected from the nozzle. Because of this it is more dense, homogeneous, strong and waterproof than any other process.

Gunnite is not placed in forms; it can be impacted onto any type of shape of surface, including vertical or overhead.

See How Gunnite works

The Product:

1. Adhesion or Bond
The bond with properly cleaned concrete, brick, or stone actually is stronger than the material to which it is applied.

2. Density
The force of application by compressed air and the “peening” effect of the larger particles result in a very dense and impervious mass with an absolute minimum of entrained air.

3. Compressive Strength
Extreme strength, hardness and abrasion resistance of the material are attributable to two factors . . . the method of placement and the addition of only the proper amount of water. Ultimate compressive strength has been tested at 6000 psi or greater in 28 days.

4. Resistance to Absorption or Percolation
The density and watertight qualities of dry-process shotcrete will allow it to withstand conditions which ordinarily destroy or damage concrete. It has been successfully used for structures subjected to alkaloids, acids, salt water and certain corrosive fumes.

5. Low Water-Cement Ratio
The excellent physical properties of the material are due to the water content being only the amount needed to satisfy chemical hydration (averaging 3 to 3 ½ gallons per bag of cement). In addition, placement at high velocity against a surface instead of forms results in the rejection of excess material or “rebound”.

6. Expansion
Expansion characteristics of dry-process shotcrete are almost identical to low-carbon steel. The expansion allows for flexibility of the steel-reinforced mass and also minimizes cracking.

7. Fire Resistance
Underwriters' laboratories, after conducting extensive tests on slabs, gave dry-process shotcrete extraordinary allowances for reinforced construction.

8. Forms
Dry-process shotcrete can be placed against surfaces without forms and will conform to any irregularities in the surface. Thicknesses can be from a fraction of an inch to 10-12 inches and more.
