Our Projects

Underwater concrete

Underwater concrete was recently applied in FORUM Rotterdam at the bottom of a deep construction pit for the realisation of a lift shaft for trucks. This floor can withstand the pressure of groundwater.

Fishing boat Hell - 103

Due to an unforeseen circumstance, a fishing vessel sank to a depth of 65 metres near the coast of Gdansk last year. Qceas was contracted to recover the vessel. We promptly salvaged the vessel.

The Entrance to Amsterdam

The renewal of the area on the centre side of Amsterdam Central Station. A bicycle shed for 7,000 bicycles was built under water. We had to pull out all the stops for this complex project.
