Soil-reinforced geogrid offered in 18-foot widths
Strata Systems, Inc., a company specializing in advanced geogrid solutions for soil reinforcement and slope stabilization, is now offering its StrataGrid line of geosynthetic products available in 18-foot widths.
Measuring 18-foot wide by 600-foot long, each panel unfurls to cover 1,200 square yards of subsoil. Compared to geogrids manufactured in standard 12, 6 and 4-foot widths, StrataGrid’s wider coverage translates into less individual rolls for installers to handle per job; and fewer seams to be spliced between adjacent panels.
StrataGrid is an advanced geogrid fabric made exclusively from high tenacity, knitted polyester yarns. Manufactured by Strata Systems in an array of grid apertures, strengths and designs, StrataGrid provides superior grade separation performance in segmental retaining wall and slope soil reinforcement applications.
Unlike other geogrid materials that require end-to-end splicing of rolls, using the more labour-intensive Bodkin connection, StrataGrid needs only a simple overlap connection between end rolls.
StrataGrid is the first geosynthetic material knitted exclusively from polyester fibre, giving it superior flexibility over geogrids made from polyethylene. One significant advantage is that StrataGrid unrolls flat, retaining virtually no materials memory. Additionally, StrataGrid maintains uniform contact with subgrade contours, making it easier to install in cold weather. These same properties also mean StrataGrid is easier to backfill and less likely to be damaged during fill placement operations.
When worker safety is an issue, Strata-Grid again has the edge in job-site performance.
While polyethylene geogrids can become slick and difficult to handle when wet, StrataGrid provides an easy-to-grip surface under all weather conditions.
Technical director Lance Carter says the StrataGrid’s time and labour saving advantages go well beyond materials handling. “With its superior tensile strength, StrataGrid eliminates the need to place soil layers between reinforcing layers. Bi-directional tensile strength is achieved by placing opposing layers of StrataGrid directly on top of each other with no soil between the layers, resulting in significant savings in construction time, labour and materials cost.
Independent soil interaction testing has confirmed that even when no soil is backfilled between opposing layers, Strata-Grid develops full pullout and anchorage capacity.
