PREFABRICATED VERTICAL DRAINS
|

| |
Garware-Wall ropes Ltd. has developed the Pre-fabricated Vertical Drains for the ground improvement applications.
GWRL was the first in India to Manufacture, Supply and Install PVD’s
The prefabricated vertical drain is a long flat tube of woven or non-woven geotextile with a HDPE core inside. For construction of structures on sites underlain by thick strata of soft cohesive soils, a method of foundation soil improvement is generally required to prevent bearing capacity failure and or to avoid excessive total and differential settlements. These soft soils have a very low bearing capacity to due to their saturated state, the PVD’s are used to increase the bearing capacity of the soil by removing the excessive water present inside. |
|
The water is trapped inside the soft cohesive soils, and the consolidation of which will require a long period. The PVD’s provide the path for the trapped water to come out of the soil, thus accelerating the rate of consolidation.
The Garware-Wall ropes Ltd. can manufactures the HDPE core and the woven geotextile as per the requirement of the site. Our PVD’s covering geotextile is welded by ultrasonic welding for best performance. |
