Geosynthetics are a diverse family of various types of polymer materials formed into extruded grids and nets, blown film sheets and membranes, as well as woven and nonwoven geotextile blankets. Geosynthetics have proven to be among the most versatile and cost-effective ground modification materials.

In road construction geosynthetics are used to strengthen base sections, improve surfacing and enhance drainage. The materials reinforce, separate and stabilize subgrade and base materials providing the benefits of reducing aggregate requirements, simplifying construction, increasing roadway life and reducing future maintenance. Geosynthetics also prevent accidents as they are able to withstand large lateral deformations and vertical differential settlements. Road structures can at times fail prematurely due to lateral displacement and weakening of base course aggregate. Geogrids or geotextiles are used to enhance performance or reduce the thickness of a permanent road, even when constructed on a reasonably competent foundation. They provide tensile strength in the earth mass in locations where shear stress would be generated in road works. Moreover, they allow rapid dewatering of the roadbed, and preserve their permeability without losing their separating functions.
