Arnhem, the Netherlands – After intense in-house research and development work Colbond have launched their latest product innovation for civil engineering applications: a Prefabricated Vertical Drain (PVD) marked by a unique hydraulically designed drainage core bonded to nonwoven filter layers over its entire surface. The core is shaped into a solid channel profile and ensures outstanding water flow rates, resulting in quicker settlement of soft soils and a significant reduction of the construction time for infrastructure projects on marshland areas or reclaimed land.
COLBONDDRAIN® CX1000 VERTICAL DRAIN
A pioneer in the development of geosynthetic products, Colbond introduced the first Colbonddrain® CX1000 vertical drain more than thirty years ago. Backed-up by practical experience gained from hundreds of millions of metres of vertical drain installed worldwide and extensive laboratory tests, Colbond have since continually improved their Colbonddrain CX1000.
The latest CX1000, however, sets a new benchmark in the field of soil consolidation products.
The unique combination of a patented solid core firmly covered with strong, yet permeable nonwoven filters increases water flow capacity by more than 50%.
The fully bonded composite maintains these discharge rates even when buckled beyond 90°, which can happen as upper clay-layers settle. As a result, the time soil takes to consolidate before construction can take place is reduced significantly, resulting in substantial cost savings for contractors and project owners.
“After years of dedicated work accomplished by our product management and R&D teams, I am very pleased that we can now offer this new PVD, which is without equal in soil consolidation performance,” said Blair Rawes, director of sales and marketing. “During the past few months, the drain has been introduced to and been tested by a number of major customers. The feedback received was positive and confirmed our high expectations on the potential of this new PVD.”
