Consolidation geocomposite COLBONDDRAIN®

polymerfoundation

Colbonddrain is a high quality Prefabricated Vertical Drain (PVD) which is usually installed with a purpose built installation rig mounted on a hydraulic excavator. Colbonddrain was developed in partnership with leading European consultants, laboratories and geosynthetics specialists to create a highly effective solution for a major engineering challenge. The design of Colbonddrain is based on a unique extrusion and shaping technique which creates a tough geocomposite. When the sub-grade of a construction site is too weak to bear normal construction activity, Colbonddrain will speed up consolidation considerably. Colbonddrain is a tough and durable prefabricated vertical drain (PVD), designed to extract pore water from soils to achieve 90% consolidation within six months. Thanks to its high performance Colbonddrain is often the chosen PVD for major, technically demanding projects. Function • Vertical drainage Application areas • Soft clay • Weak soil • Marshland areas
