There are several applications for PVD wick drains, including increasing waste containment sites and reducing down drag in piles. They can also be used to collect contaminated groundwater, especially when installed with cutoff walls. This can help accelerate the consolidation process. Listed below are some of these applications. To find out how they can benefit you, read on. Here is a brief overview of the main benefits of PVD wick drains.
PVD wick drains are installed with a hollow steel mandrel encasing the PVD material. The mandrel is then driven into the ground by a machine that uses a stitcher to drive the mandrel into the ground. Once the mandrel is in place, the wick is looped through a steel anchor, securing it in place. Once the wick drain has reached the desired depth, the mandrel is removed from the ground approximately 15 to 20 cm above the surface. The wick drain is then cut at the desired depth.
The duration of consolidation depends on a variety of factors, including the quality of the geotextile and the amount of surcharge. If the wicks are placed strategically and in triangular configurations, they can accelerate the consolidation process and virtually eliminate post-construction settlements. Moreover, they are easier to install than stone columns. And because they are inexpensive, they are an excellent choice for many projects. The benefits of PVD wick drains are many.
PVD wick drains can be installed on a variety of substrates.

PVD wick drains are lightweight, so installation is simple. Their width-to-thickness ratio is 30 to 35. Their surface area for seepage is 0.2 to 0.3 in2/0.4 in (1 mm) of length. Generally, a wick drain should be installed three to eight feet apart. The design parameters for PVD wick drains will be discussed below. In addition to the cost-effectiveness of the product, its durability are important factors in selecting a suitable drainage system.
A wick drain installation process can be simple or complex, and involves the use of stitcher equipment. Stitcher equipment is mounted on a crane or backhoe. It comprises of a vertical mast that contains an installation mandrel. A mandrel contains the wick drain and is hydraulically pushed or vibrated into the ground to the desired depth. Once in place, the mandrel is removed. A wick drain is then cut to ground level.
