In road construction on weak soils, reinforcement layers can help to reduce the required thickness of the unbound base course stabilizing structures on soft ground or in unsettled areas. The reduction of the thickness of the base course results in considerable cost savings during the construction phase. In use, reinforcement layers absorb forces originating from traffic and significantly delay the onset and propagation of cracks in the surface, thereby prolonging the life of structures considerably.

In railway construction, and in the maintenance of existing track systems, multiple layer geosynthetic reinforcements provide very effective stabilization.

Colbond's Enkagrid MAX and Enkagrid TRC geogrids are reinforcement products one can count on in these and similar applications. Even on the poorest soils, they can be used to form a base course meeting the requirements of the specific superstructure. As a multifunctional geocomposite, Enkagrid TRC not only reinforces, but also separates and filters the soil layers. Both Enkagrid MAX and Enkagrid TRC are biaxial geogrids, absorbing forces equally both longitudinally and in transverse direction.
