gcsBarriers™ are anotherextension of the powerfulGCS™ technologies
gcsBarrier™ On Duty The Colorado RockfallSimulation Program (CRSP) was used to determineheight of this gcsBarrier™. Note the slope grading uphill of the gcsBarrier™to control bounding heights of incoming rocks

Design and Construction of a gcsBarrier™ is the same 1, 2, 3 processused for Walls, Abutments, Piers and Deflection barriers ---Two rows of CMUs, a lift of granular backfill and a sheet of geofabric.

Elegant Combination of a GCS™ Box Culvert Design As a Portal for a Mine Entry AndAn Elevated, Thickened GSC™ Wall as a gcsBarrier™ for Rockfall Protection
ROCKFALL PROTECTION ON I-70Designed by Barrett for Colorado DOTThis GCS™ Wall is 26 feet high and hasA 30 foot wide rockfall catchmentBench on top.This GCS™ Wall has a truncated base.The bottom geofabrics are only3 feet wide, and progress to 30 feetat the top. Very efficient – unlike MSEwe avoided excavation of bedrockat the base.This wall was carefully monitored.Shown here is CDOT’s John David –email@example.com -CDOT’s project manager. Deflection wasLess than ½ inch and strains in theGeofabric were less than ½%, which isTypical for GCS™ performance.
THIS SUITE OF SLIDES SHOWING gcsBarriers™ SERVES TO ILLUSTRATE THE VERSATILITY AND ADAPTABILITY OF THE POWERFUL GCS™ TECHNOLOGIES. THESE EXAMPLES ARE COMPELLING REASONS TO BEGIN THE TRANSITION FROM MSE TO GRS/GCS™ CONCEPTS. MSE WAS A TRANSITIONAL STEP AND IT HAS SERVED ITS PURPOSE.
