ROADWAYS "SUBGRADE STABILIZATION & SUSTAINABLE TRANSPORTATION INFRASTRUCTURE"

Unpaved, Haul, Access & Gravel Roads

Weak subgrades and heavy loads pose the greatest challenges to the performance of aggregate surfaced roadways, laydown yards, and working platforms. Both issues can lead to surficial rutting which can make these surfaces unusable.

BaseLok Geogrids are some of the strongest and stiffest geogrid products on the market today. Research has shown that strength and stiffness are key to the performance of geogrids over soft soils. The high strength and stiffness of BaseLok geogrids enhance aggregate interlock and provide a bridging mechanism which increases the effective bearing capacity and spreads the applied load over a wider area. Additionally, these properties along with a high rib profile enhance the BaseLok geogrids’ lateral restraint of aggregate making BaseLok geogrids an ideal choice for bridging soft soils.

BaseLok GeoCells are utilized when additional support is needed beyond what a geogrid can provide. GeoCells work by confining infill material within a cell. Unlike geogrids which typically require quality aggregate backfill, BaseLok GeoCells can be used with a variety of infill materials including sand, recycled material, aggregate and soil-aggregate blend, etc. The physical barrier present within BaseLok GeoCell provides the ultimate lateral confinement. BaseLok GeoCell is often combined with BaseLok GeoGrid or Fabgrid creating the BaseLok Foundation Performance System (FPS). The BaseLok FPS is utilized in extreme applications where both very soft soils and heavy loads exist. Contact your BaseLok Engineering Team for design support for BaseLok FPS.
