Separation is the placement of a flexible geosynthetic material, like a porous geotextile, between dissimilar materials so that the integrity and functioning of both materials can remain intact or even be improved. Paved roads, unpaved roads, and railroad bases are common applications.

Earthmate® Geosynthetics
Earthmate Geotextiles serve to separate layers of stone in civil engineering applications for highways and roads, car parking lots and many other applications. By separating the subgrade soil and subbase fill materials, the geotextile preserves the strength characteristics of the aggregate material and also preserves the drainage behavior. It also helps to restrict the upward flow of water and finer soil particles into the gravel, which would otherwise drastically reduce the strength of the gravel.


Earthmate® is a leader in the geosynthetics industry for providing innovative and cost-effective solutions to support the unique challenges of civil engineering, environmental and geotechnical projects across a variety of sectors including: road construction, water and waste management, mining, oil & gas, retaining wall, containment and agriculture.
