The concrete joints in many old halls move both horizontally and vertically. There can be many different causes. For instance, the concrete’s substructure may not have been compressed strongly enough, or the concrete may have broken down.
This invariably leads to parts breaking out of the joint area and causes damage not only to the flooring, but to forklift trucks as well.

A proven solution to the problem is to drill out the base on both sides of the joint and injecting low-shrinkage mortar. In doing so, the concrete section should no longer move vertically and repair work on the joint area can start.

We offer a variety of systems for this purpose. See NIEWIELITH ‑ Joint.
