Strata Systems, Inc. is a manufacturer and worldwide distributor of a diversified group of soil reinforcement products including Stratagrid, Microgrid, StrataBase, StrataWeb and the Sleeve-It System fence-post anchoring system behind SRW. No other single geosynthetics company can match the range and depth of our product line. Strata`s quality control testing is performed by independent laboratories in the United States. Test results are available upon request. Strata Systems promotes the technology of soil reinforcement and actively supports the civil and geotechnical engineering community through distribution of technical information. Strata Systems is routinely involved in industry associations that promote the development of national standards. Strata employees are members of various technical committees within ASTM, Geosynthetic Institute (GSI), and National Concrete Masonry Association (NCMA).
Strata Systems is a world leader in the production of geogrid reinforcements. Strata Systems has a top quality staff of professionals. Our customer and technical service is second to none, providing a level of service and support unsurpassed in the industry.
Our mission is to create a sustained level of reasonable profits by manufacturing, marketing, and supporting the use of high quality, polymeric soil reinforcement products.

To assure the continued success of our company and the satisfaction of our customers, we have consistently developed innovative products for soil reinforcement. As part of this same philosophy, Strata joined Glen Raven, Inc. in 2007. Founded in 1880, Glen Raven is a global leader in performance fabrics. Glen Raven's expertise in high-speed knitting and proprietary coatings provide significant growth opportunities for Strata. With full in-house manufacturing capabilities and R&D resources, Strata Systems is positioned to continue with innovations that will assure Strata's long term growth.
StrataSlope is available to you for quick and easy evaluation of your reinforced soil slope structures. StrataSlope produces the optimal Stratagrid reinforcement layout (i.e. length, spacing and type) while taking into account appropriate geosynthetic material properties, reduction factors and design safety factors. The software considers tie-back and compound stability using log-spiral failure surfaces, direct-sliding using conventional two-part wedge mechanism, and deep-seated stability analysis via Bishop Method. The softwre is optimized for the design of reinforced slopes with simple geometry (i.e. single-tier; homogenous soil zones - reinforced, retained and foundation; and competent foundation conditions), and provides capability of performing quick global stability evaluations of reinforced soil walls using geogrids.
- Provides quick analysis of reinforced slope structures
- Valuable tool for material estimating
- Considers Limit Equilibrium using Bishop’s Method of Slices
- Evaluates Internal Stability (Tie-Back and Compound) based on Log-Spiral Surfaces
- Addresses Direct sliding stability using 2-Part Wedge method
- Directly Integrates Strata Soil Reinforcement products
Strata performs extensive testing to quantify and document the material properties and performance characteristics of our products. Strata works closely with recognized testing labs and utilizes third-party, independent test labs for our product quality assurance testing. Additionally, Strata's quality management systems is ISO 9001:2000 certified, which means you are assured the proper measures are taken in product design, raw material procurement, manufacturing, testing and distribution.
The Stratagrid Construction Overview Document provides an excellent overview and summary of our product construction and testing. This information provides you with the documentation for our recommended performance characteristics and design parameters. Upon your request, we can also make available copies of the laboratory reports or published papers referenced within.
Strata seeks to provide you with the resources and tools that meet your design needs. Designers and Engineers for segmental retaining wall projects are in constant need of the latest geogrid and geogrid-wall unit connection data.
