Product Specification Prefabricated Vertical Drain (PVD)
PVD (Prefabricated Vertical Drain) is one of the geosynthetic products that functions as a drainage water. PVD is a composite material consisting of a core and filter (filtration) (Figure 1). The PVD function in the work of repairing clay (soft) preloading methods with the use of PVD is to accelerate the time of the process of soil consolidation (Figure 2). (PVD) can accelerate consolidation time up to 20 times faster than without PVD or vertical drain.
This PVD or Prefabricated Duct can accelerate the consolidation time because PVD can shorten the pore drainage distance. If without using PVD, the time to consolidate soft clay will take longer and it will certainly take a lot of time. Whereas when using PVD, the time to consolidate soft clay soils will be faster and more effective.
Advantages of PVD materials:
- Has high tensile strength
- Resistant to chemicals
- Has a high drainage capacity
- Resistant to changing temperatures
PVD (Prefabricated Vertical Drain) Application:
- New land clearing on soft soil
- Beach reclamation
- Land for new housing
- Making railroads, highways and airports
- Construction of land for embankments
