Subgrade Improvement

Weak foundation soils (subgrades) are a common problem in road construction. Whether it be a temporary access road or a permanent road built over soft subgrade, a large deformation of the subgrade will lead to deterioration of the paved or unpaved surface. Geogrids and geotextiles distribute loads more efficiently, increase the effective bearing capacity of the subgrade and provide a better alternative to costly, conventional stabilization methods.

BX Geogrid

Biaxial (BX) Geogrids
Biaxial Geogrids enhance load distribution over soft subgrades, similar to how a snowshoe distributes a person's weight evenly over a large area of snow. Geogrids interlock with aggregate to create a stiffened granular platform.

Subgrade Improvement

Woven Geotextiles
Woven Geotextiles combine the physical properties of low-elongation and high-tensile strength to provide support and stability when building over soft subgrades. Woven geotextiles provide separation and a tension-membrane effect between the underlying weak soils and the road structure.

Nonwoven Geotextiles
Nonwoven Geotextiles are made from polypropylene fibers that are needle-punched to form a dimensionally stable network. Nonwoven Geotextiles provide support over soft, saturated subgrades by providing separation between the underlying weak soils and the road structure.
