A Soil consolidation project

In this project about 700.000 meters of wickdrains (prefabricated vertical drains-PVD) were specified.

Working with sand drains need more time and work.

The soil should be consolidated quickly, and the road is near the sea.

It was like draining the sea.

At the top of the soft soil a sand layer was placed to move the machines and also for drainage.

The contractor preferred a special soil consolidation composite - Colbonddrain.

At the top of the soil there were a 1 meter thick soil which was difficult to penetrate in some areas. The bottom was very soft.

A simple wickdrain installation equipment attached to an excavator worked well.

The wick drains installed upto 18 meters depth.

At the end the consolidation was done succesfully.
