A thin surficial crust layer (typically 2m) of hard to stiff clay exists that is underlain by generally soft to firm soils.

The loads associated with the bridge structures would be carried by piles that would be driven through the RGM after it was constructed.  Using woven polyester geogrids, Maccaferri used 3 layers of reinforcement at 0.5m vertical spacing. The strain within the layers of geogrid was limited to between 2-3%.  With a very small width to length ratio, the loading was primarily transverse to the longitudinal axis of the granular foundation.Using woven polyester geogrids, Maccaferri used 3 layers of reinforcement at 0.5m vertical spacing. The strain within the layers of geogrid was limited to between 2-3%.  With a very small width to length ratio, the loading was primarily transverse to the longitudinal axis of the granular foundations under the MSE walls, so mono-directional reinforcement oriented transversely across the granular pad was used.The tensile strength of the geogrid was determined based upon the load applied to the surface of the RGM, the depth of the reinforcement below the MSE structure and foundation soils at each site. MacGrid\u00ae WG5, WG6, and WG8 have been used to build numerous RGM structures.<\/p>\n                    <\/div>\n                <\/div>\n            <\/div>\n        <\/div>\n    <\/div>\n    <\/div><div class=\"wp-block-mac-container-block box-container\"><div class=\"container\"><h2>Used Products<\/h2><div class=\"row\"><div class=\"col-12 col-sm-12 col-md-12 col-lg-3 col-xl-3 col-xxl-3\"><div class=\"wp-block-mac-card-new-block block-latest-news-container\"><div class=\"card\"><div class=\"content-images\"><img decoding=\"async\" class=\"box-image\" src=\"https:\/\/www.maccaferri.com\/ca\/wp-content\/uploads\/2024\/04\/Header-Monoaxial_Geogrids\" alt=\"MonoAxial GeoGrids\" title=\"MonoAxial GeoGrids\" \/><\/div><div class=\"card-body\"><h6>MonoAxial GeoGrids<\/h6><span class=\"abstract\">Paragrid\u2122 WAn enhanced high performance knitted geogrid characterized by a very high modulus and the lowest reduction factors.
