ENGINEERED SOLUTIONS E’GRID® Geogrids Proven Geogrid Technology for Economical Road, Rail and Similar Load Support Systems

Aggregate Confinement Aggregate Connement Proven Technology - Proven Economy Thirty years experience in U.S. and worldwide applications has proven the performance and economy of using biaxial geogrids to confine aggregates subjected to dynamic loads. Contech Engineered Solutions LLC bring to you an entire suite of high-quality biaxial geogrids that provides project-proven results. Reduced Aggregate Layer Thickness Biaxial geogrids confine aggregate subjected to dynamic loads, restraining movement and effectively increasing the aggregate shear strength. In turn, vehicle-induced loads are spread...

Biaxial Geogrids Meeting U.S. Standards E’GRID® Geogrids Unbalanced (rectangular) aperture, punched-and-stretched, polypropylene biaxial geogrids have been the standard in the United States since their introduction in the early 1980s. With nearly 30 years of in-the-ground performance history and cost-reducing results, unbalanced biaxial geogrids remain the U.S. choice for trafficked structure applications. E’GRID geogrids provide the option to continue this wellproven practice. The combination of long-established mechanical, geometrical, and durability characteristics enables E’GRID geogrids...

Modulus, Interlock, Stiffness, Durability Proven Technolgy - Proven Economy Aperture & Rib Modulus Considerations Vehicles, whether autos, trucks, or rail cars, impart large, symmetric, dynamic loads into surfacing materials (asphalt, concrete, etc.), aggregates, and subgrades. The load-transfer mechanism, from wheel to subgrade, is three-dimensional, with changing vector orientation and magnitudes at any one point in the structure as the wheels moves. Therefore, to optimize aggregate shear strength and its resulting load-spreading characteristics, a confining geogrid must restrain lateral particle...

Modulus, Interlock, Stiffness, Durability E’GRID® Geogrids Balanced (square) aperture, punched-and-stretched, polypropylene biaxial geogrids have been the worldwide standard for nearly 20 years. Countless thousands of successful projects are in place with each possessing unique soil, contractor, equipment, weather, groundwater, and loading conditions. Given this historical breadth of proven performance, E’GRID biaxial geogrids are far more than “fullscale laboratorytested”or “full-scale field-trialed.” Balanced aperture E’GRID geogrids, distributed by Contech Engineered Solutions, meet the demanding...

Comprehensive Quality Management System Biaxial Geogrids Meeting U.S. and Worldwide Performance Needs Design using biaxial geogrids is empirically based. Therefore, the supplier’s quality system must ensure that products shipped to a project meet or exceed physical properties of the research and testing programs used as a basis for design. The only way to ensure product-quality uniformity is to require a comprehensive quality management system with full traceability. Critical components of such a system include a documented manufacturing Quality Control (QC) program, third party Quality Comprehensive...
