Renovation of jointing transitions A6

SealteQ specializes in the repair of expansion joints, among other things. Our colleagues from SealteQ Heerenveen carried out the work on the A6 for RWS. They were under some time pressure, because the road could not remain open longer than Sunday morning, 9:30 AM. Fortunately, this time pressure was not a problem at all. The work was completed well before the deadline, despite the storm.

Joint transitions

Expansion joints? Rattling? Expansion joints form the link between roads on solid ground and on a viaduct or bridge. They must bear the traffic, absorb movements due to traffic and temperature of the viaduct or bridge, and protect the underlying structure against damage from leakage.

Collaboration Partners

SealteQ does not do such a job alone, of course. During this renovation project, SealteQ also worked with
F.C. Nienhuis
in addition to RWS. Closing a section of highway must be done as safely and efficiently as possible. F.C. Nienhuis provided the correct traffic measures so that our colleagues could work safely.

Various Specializations for Renovating Expansion Joints

The renovation work consisted of 2 parts, on the one hand work on the steel structure and on the other hand on the concrete. SealteQ has specialists in both fields. As a result, we were able to make a combined plan for all renovation work. Given the limited time our colleagues had, such good preparation was useful. The job consisted of blasting the steel structure to remove the rust. By applying a coating, the steel structure is better protected and lasts longer. Then we placed the anchors that ensure that the expansion joint stays in place. That is precise work, because the steel must not be damaged when placing it. Then the expansion joints are secured with rapid cement and poured with steel fiber concrete. Finally, there is a final check for any protruding steel fiber. If everything is in order, the mortar can harden and the work is finished.

Safety

For SealteQ, the safety of our colleagues is the most important thing. The colleagues work with tools that are NEN 3140 approved. This means that the electrical tools are safe to use. That inspection also includes safety procedures that must be followed. In addition, RWS provided our colleagues with safety clothing. As with all jobs, the colleagues on the A6 also worked with personal protective equipment. This includes safety glasses, special shoes and helmets. Outdoor jobs always pose a risk. You are dependent on the weather. SealteQ always plans a Go or NO GO moment, so that we can switch at the last moment. Fortunately, the work could continue despite the storm. We are always prepared for weather changes and in this case had facilities with us to shield the workplace against rain and storm.
