SoilWicks is a ground improvement contractor that specialises in the supply and installation of Prefabricated Vertical Drains (PVDs). Established in 2000, SoilWicks has grown to position itself as Australia’s leading installer of PVDs.
Sand Compaction Pile (SCP) was adopted in order to mitigate liquefaction of upper granular soil layer and accelerate consolidation settlement of cohesive soil layers. A combination of Prefabricated Vertical Drain (PVD) and Dynamic Compaction were also adopted for the same purposes as SCP. Settlement was monitored after raising the embankment.
Prefabricated Vertical Drains, also known as Wick Drains, are used to accelerate the consolidation of compressible soils. The consolidation of compressible soils involves the removal of pore water from the soil. This is traditionally done by applying a surcharge of preload to the construction area to “squeeze” the water out.

Jan 18, 2020 · Prefabricated vertical drains (PVDs) are widely used to accelerate the consolidation process within soft ground. The overall degree of consolidation (DOC) of soft ground is highly dependent on the arrangement of PVDs, such as their length and spacing. Nevertheless, only the ranges of spacing and length are recommended in codes and standards, which renders it difficult for designers to ...

Sand drains are basically boreholes filled with sand. The installation causes disturbances, especially in soft and sensitive clays, which reduces the shear strength and horizontal permeability. Prefabricated Vertical Drain is a prefabricated material consisting of a plastic core covered by synthetic geotextile filter jacket.
within schedule. Prefabricated vertical drains (PVD) have been generally used to decrease the overall time required for comple tion of primary consolidation by shortening the drainage path length. PVD has largely replaced other drainage techniques due to its advantages of economic competitiveness, less disturbance of the soil mass, speed and
In the vertical application, the wick drains are installed with specialized equipment that drives the strips of wick drain into the ground. Vertical wick drains, in conjunction with a preload, provide a drainage path for water-saturated areas to speed up settlement. Saving the project time and money compared to a preload alone or having to use ...

Preloading and Prefabricated Vertical Drains (PVD) is a ground improvement technique used to increase the consolidation process of clayey soils by means of shortening the drainage path.
Apr 13, 2020 · Vertical drains offer a shorter pathway for water to exit the soil, while preloading using fill surcharges the foundation soils. Historically, a number of different types of drains were used, from sand drains to cardboard drains. Today, the most common vertical drain for ground modification is a prefabricated vertical drain, or PVD.
