Ypres - Ypres-Yser Canal

For many years maintenance dredging had been non-existing on this canal due to lack of funding.  In 2008 a budget was raised to dredge the canal to such an extend that a restricted passage to shipping was created.  About 50% of the contract, at the Ypres side of the canal, has been carried out by Ghent Dredging.

This contract could serve as a perfect example in the way our dredging and environmental divisions were complementary to each other.

 .

Dredging was carried out using a pontoon mounted 14-tonnes excavator.

 .
 
 

Elevator barges loaded with silt were discharged alongside a pontoon equipped with an excavator fitted out with a DOP-1815 dredge pump.  After adding water to the sludge the pump discharged the silt into dewatering areas.

 .
 
 

Once inside these areas dredged silt is pumped into geocontainers added with polymers.  Through the addition of polymers the dewatering process is accelerated and after a couple of days silt has turned into soil.
