How does gravity filling work?

Gravity filling is the simplest filling method. The uncomplicated construction and operation of gravity filling machines permit them to run with a minimum of maintenance. The supply tank (more properly called the filler bowl) is the upper, central part of the machine. Filling stems are attached to the bottom surface of the bowl at each container filling point. A vent tube extends upward into the filler bowl to a point above the liquid level. To begin the filling operation, the container is raised by the platform until it contacts the filling stem. The platform then continues to raise the container against the stem, opening the filling valve. Low viscosity monomers and resins can be used to seal cracks with surface widths of 0.03 to 2 mm by gravity filling. High-molecular-weight methacrylates, urethanes, and some low viscosity epoxies have been used successfully. The lower the viscosity, the finer the cracks that can be filled.

What is resin injection?

Resin injection is used to repair concrete that is cracked or delaminated, as well as to seal cracks or joints in concrete that is experiencing water leakage. Epoxy resins are used to structurally rebond cracks that are dormant and relatively dry, while various polyurethanes and some methacrylic acrylates are used to seal cracks or joints that leak water. It is usually not possible to structurally rebond cracks that are leaking water, are dirty, or are very wet. Also, due to the high cost of resin injection, it is not normally used to repair shallow cracks, drying shrinkage cracks, or pattern cracking. Therefore, if repairs are needed for these types of cracks, a sealing approach is usually more effective.

What is concrete sealing and coating?

Concrete sealing and coating compounds are applied to cured, dry concrete as a maintenance and repair procedure to reduce or prevent penetration of water, aggressive solutions, or gaseous media.

These materials are not suitable for repairing badly damaged or deteriorated concrete, but they are suitable for sealing concrete surfaces and cracks in concrete that is in overall good condition.

In general, thick repairs refer to repairs that are about 3 inches thick and that completely encompass at least some reinforcing steel from the existing structure. If the repairs do not encompass any steel from the existing structure, they are typically at least 6 inches thick. In such cases, consideration should be given to anchoring additional reinforcement (that will be embedded in the repair material) to the existing concrete. Typical examples of thick repairs include replacement concrete, preplaced aggregate concrete, shotcrete, and silica fume concrete.
