Ground Improvement is enhancing the poor ground conditions by mechanical means & the inclusion of geosynthetic products. It enhances the soil properties of foundation soil thereby increasing its bearing capacity to support the structure. Various ground improvement techniques are discussed below.
It is manufactured using high molecular weight (>25000 gm/mol) and high tenacity polyester yarn. The polyester yarn are knitted together to provide its design strength in both machine and cross machine direction and finished with polymeric coating into a grid like structure.
These are cellular confinement system which forms a rigid base for the weak soil to improve the bearing capacity of the ground. It is made up of ultrasonically welded high density polyethylene strips and used in it’s expanded form filled with soil. The cell depth and weld spacing can vary as per project requirements.
PVD drains, also known as Prefabricated Vertical Drains or Wick Drains, are geotechnical solutions used in soil improvement projects to accelerate the consolidation of soft or loose soils. They consist of vertical strips made of synthetic material, typically polypropylene, that are installed into the ground.
These are vertical granular columns used to stabilize the weak ground by increasing its shear strength thereby enhancing bearing capacity and reducing settlements to support the structure.
