BaseGrid 13

   »Stabilization - does not separate well and may require a geotextile separator.
   »For use with larger aggregate. This product's aperture size of 1.80 x 2.50 inches is larger than our BaseGrid 11 and BaseGrid 12 products.

Geogrids Vs. Woven Geotextiles

If you are considering our BaseGrid base stabilization geogrids for your park-on/drive-on project, you may want to consider using a woven slit-film geotextile instead. Many of these woven geotextiles had been used successfully for soil reinforcement nearly a decade before the development of polypropylene geogrids.

Many geotechnical engineers practicing worldwide understand the type of geosynthetic used is irrelevant to the design of a reinforced soil structure. What is important is the geosynthetic's in-situ performance. As such, woven slit-film geotextiles are stronger and offer an advantage over any geogrid: separation. Geogrids have openings, geotextiles do not.

At the Geosynthetics 1993 Conference, a paper titled "A Field Evaluation of Geosynthetic Reinforced Haul Roads over Soft Foundations" concluded that "[t]he aggregate subbase layer [in the geogrid sections] was contaminated with the cohesive subgrade soil . . . [however] excavation of the geotextile sections indicated no contamination of the aggregate subbase."

Geogrids are beneficial only when utilized along with a geotextile for bridging very weak, high-organic soils such as peats. Take a look at our Woven Stabilization & Separation and Woven Reinforcement sections for more information on woven geotextile alternatives.
