Polypropylene Soil Reinforcement Geogrid ASTM D6637 ISO9001

ASTM D6637 Standard TGSG15-15 Type Soil reinforcement PP Biaxial Gegrid

PP Biaxial Gegrid Introduction: 

 
The properties of Biaxial Geogrids, made of Polypropylene (PP) with their square apertures, high tensile strength and optimised geometry of nodes and ribs make them equal to any other similar material. The reinforcing action of PP Biaxial Geogrids lies mainly in confining soil and increasing its shearing resistance by a process of interlocking between the square ribs and the soil. The load dispersal effect from the interlocking mechanism is highly effective and can reduce sub-base thickness and construction cost. PP Biaxial Geogrids can be used with any kind of mechanical fill material. Two aperture size ranges are available for optimum matching with project fill.

A geogrid is a geosynthetic with large openings or apertures. Geogrids are used as soil reinforcement below roads, under structures and behind retaining walls. They also reinforce paving overlays.

Geogrids can be uniaxial (strength in one direction) or biaxial (equal strength in both directions) and are made from polyester, polypropylene or fiberglass. Manufacturing methods include woven, knitted, extruded or otherwise “integrally formed.”

Biaxial Geogrids for Base Stabilization

Biaxial geogrids are designed to have roughly the same tensile strength in both directions and to distribute loads over a wider area, increasing the load capacity of the soil. Base reinforcing geogrids interlock with the aggregate to confine the base and reinforce the subgrade. In paved or unpaved applications, they reduce rutting and help maintain the desired aggregate depth.

Qijie Company offers BaseGrid biaxial geogrids for base reinforcement. BaseGrid geogrids are the classic polypropylene, single-layer, “punched and drawn” geogrids that have been specified repeatedly and used effectively for decades.

Uni-Axial Geogrids for Slopes & SRWs

Uniaxial geo grids typically have their tensile strength in the machine (roll) direction. They are mainly used to reinforce the soil mass in a steepened slope or segmental retaining wall. On occasion, they function as a wrapping to confine the aggregate in the wire forms of welded wire faced steepened slopes.

Qijie Company uniaxial geogrids are made from polyester yarn, knitted or woven into a stable structure and have a PVC or polymeric coating. These flexible, user-friendly geogrids are inert to biological degradation and resistant to creep, strain and naturally found chemicals.

Qijie is pleased to offer Stratagrid geo grid by Qijie Company for retaining walls and slopes. Stratagrid is the only precision knitted uniaxial geogrid available in the market today.

Some very light strength polyester geogrids such as Stratagrid 150 are biaxial. These flexible grids are perfect for retaining walls less than 6' tall and are ideal for the novice retaining wall builder or homeowner.
