This is why we offer the longest Structure repair guarantees if using in polishing processes. MG Corporation analyzes the cracks and makes the best recommendation for the repair of each job individually. Concrete Expansion Joint Filler. The joint spacing filling is a process by which the shrinkage, construction, and isolation joints are filled. The majority of the joints in an industrial floor will consist of shrinkage, construction, and isolation in that order.

It is imperative for the continued integrity of the floor to upgrade concrete expansion joint filler frequently. The joint filling provides a two-fold purpose: protection and support for proper expansion contraction.
Protection is for the leading edge of the joint when perpendicular hard tire impact from forklift use. Support is provided when the joint filled in with a backer rod and primed with water-based epoxy.
Using a special caulking gun we distribute self-leveling sealant to a full depth within the joint, providing a closed cell. Thereby transferring the load momentarily to the shelf that has been established with the formation of the joint itself.
A joint that is not filled or filled improperly will cause a vast array of operational difficulties within a facility. Contrary to industry and property owner belief, a joint filing is not a once and done installation.
Due to high loadings, expand and contract processes – concrete joint filler needs to be applied each 3rd year. The joint should be maintained throughout the service life of the facility.

The first application needs to be delayed as long as possible after the initial place and finish. The second maintenance installation needs to be undertaken approximately 2-3 years after the initial finish of the desired joint fill material.
