Consolidating poor soils and reclaiming
unusable land is a time-consuming process, which can be accelerated considerably
by using prefabricated vertical drains (PVD). Extensive testing in laboratories
and on site show how effective PVD’s are. Also by combining the use of PVD’s
with vacuum consolidation or electro-osmosis, the level of the acceleration of
consolidation can be further accelerated to meet specific project requirements.
Proven installation procedures and the development of efficient measurement
methods make this kind of soil consolidation financially attractive, not just in
major projects such as those executed in South-East Asia and Japan
(e.g. Changi Airport, Singapore), but also in smaller construction projects in
When it comes to soil consolidation, Colbond can draw on a wealth of experience
going back nearly thirty years. The use of
PVD’s has helped speed up the consolidation of many cubic kilometres of soil to
date: a recent outstanding example was the extension of the Airbus site at
Mühlenberger Loch, Hamburg, Germany using over six million meters of PVD.
