Cocoon Holland has been working on the Campina project in recent weeks. Among other things, a pipe bridge and various branches of a silo had to be sealed at the large Campina factory in Beilen (Drenthe). A special job with the main purpose of keeping vermin out of the dairy cooperative.

Flexibility necessary with vibrating pipes

Cocoon was called in by Campina to close the pipework. It concerned a pipe bridge, 8 pipes and 2 cable ducts. Every pipe and crack had to be completely sealed. When there are loose pipes that need to be sealed, as was the case with this large company in the food industry, it is important that a flexible product is used. Thanks to the great flexibility and adhesive power of Cocoon, the job could be done. The pipes that occasionally are affected by vibrations are therefore also sealed in an efficient and elastic way with the flexible Cocoon PVC.

The implementation: step by step

How did Cocoon manage this? The project took place in a number of clear steps. First, the working area was inventoried. The area was covered with red and white ribbons, so that nobody would accidentally enter the work area of ​​Cocoon. The façade was then cleared with acetone. The non-treatment surface was covered with plastic. After this a primer layer was applied and at the same time the Cocoon foil was applied. Layer by layer. Since the different layers of sprayable Cocoon overlap, holes and openings can be completely sealed. For this project it was also important that the sprayable Cocoon get the right color. For this, a water-based paint layer was applied over the sprayable PVC.

Jed Lee, who worked on this project with 2 other colleagues, says: “” The first layers of Cocoon must be applied quickly. The Cocoon does not yet have a surface to stick to. After the first layers have adhered, the layers can be applied thicker and slower. The layers migrate with each other, so that 1 product is created. The part covered with plastic must finally be removed. Because this is partly sprayed, this is a very precise job, for which I use a Stanley knife. ”

Using the method of rope climbing

Not every pipe was equally accessible with a scaffolding or aerial platform and the openings were minimal. “You couldn’t reach it with your hands,” Jed says. Due to the difficult accessibility, it was necessary to carry out the work by means of rope access. This was quickly decided in consultation with director Alexander van der Zee. A working technique that requires specific knowledge from the technical employees of Cocoon Holland. This made it possible to reach the hard-to-reach places without scaffolding and successfully complete the entire project.
