Colbonddrain is used to accelerate the consolidation of soft soils resulting in a stable subgrade for construction to take place. Using this prefabricated vertical drain significantly reduces consolidation time of unusable land – resulting in substantial project cost / time savings.

The new, patented core is designed for maximum, unobstructed flow in all soil types.
Other product features are:
