Down in the Emirates

The ground conditions were very poor and soil consisted of layered mudstone, gypsum and sandy-silt with a high ground water table. The total project was divided into several contracts, whereas the biggest part was realized by the local firm. This section consisted of approx. 24 km in a diameter range of DN 400 to 1800 and HOBAS received the order to supply half of the project. HOBAS CC-GRP Pipe Systems were installed with a special concrete surrounding. The reason for the reinforced pipe is the tunnel boring machine, which has a certain diameter. The size of the machine does not have to be changed when the diameter of the GRP Pipe varies. The main reason why HOBAS CC-GRP Pipe Systems were taken was the smooth and highly corrosion resistant inner liner.
