Sliding door3 of the West lock at Terneuzen preserved again

In June 2000, the Bouwdienst Rijkswaterstaat granted Van der Ende straal- en schilderwerken the assignment of re-preserving sliding door 3 of the west lock at Terneuzen. On 26th January 2001, this project was completed to the full satisfaction of the Bouwdienst Rijkswaterstaat. During the intervening period, the work was carried out with a large investment of people and materials.

The lock gate was placed in a lock dock measuring approximately 60 x 20 x 25 metres and was fully surrounded by steel scaffolding by Spreeuwenberg Steigerbouw B.V.

The covering, which you can clearly see in the photograph, was placed seamlessly over the cover. This, together with the use of dust extractors, meant that the very strict environmental requirements could be met. The entire job was carried out under full guarantee.

In total, more than 800 tons of grit, 12,000 litres of paint and more than 150,000 litres of gas oil were used. The total surface area treated came to almost 11,000 m2, including 40 ballast tanks. The entire door was Sa 2½ gritblasted and then three layers of high-build epoxy coating were applied with a layer thickness of 380 µm.
