TENSAR SS30 Biaxial Geogrid Reinforcement

TENSAR SS30 is used in roadway construction for paved and unpaved roads, parking lot construction over soft subgrades, retaining walls, Geosynthetic-Reinforced Soil (GRS) walls and slopes, bridge abutments, railroads, airports, mining and logging access roads, wind farms, and landfill access roads requiring long-term soil stabilization.

Biaxial geogrids like the TENSAR SS30 lock with aggregate and distribute load in two perpendicular directions, making them ideal for wall and slope reinforcement applications. Triaxial geogrids feature a triangular, multi-directional rib shape that spreads load radially in all directions, offering superior performance for base reinforcement and stabilization beneath paved surfaces.

Yes, TENSAR SS30 Biaxial Geogrid meets DOT compliant specifications and satisfies project performance requirements for civil and environmental applications. Coleman Moore Company works directly with Departments of Transportation, municipalities, and regulatory agencies to ensure geogrid selection aligns with applicable project standards and specifications.

By mechanically stabilizing and reinforcing the subbase, TENSAR SS30 geogrid allows engineers to reduce aggregate or subbase thickness significantly. This lowers material quantities, simplifies construction logistics, and shortens project timelines. Coleman Moore uses Tensar Plus design software to calculate precise aggregate savings and deliver comprehensive cost-benefit analyses for each project.

Yes, TENSAR SS30 is specifically effective in stabilizing soft ground conditions. It separates and reinforces weak subgrade soils while improving pavement structures above. Coleman Moore also conducts on-site DCP testing with CBR value conversion to accurately assess soil strength before recommending the appropriate geogrid solution for the site conditions.

Coleman Moore provides comprehensive project support including product knowledge and material recommendations, design assistance and evaluation using Tensar Plus software, initial strategic site evaluations, installation consultation, brand and product analysis, and detailed cost-benefit analysis — all backed by over 20 years of hands-on geotechnical experience across Iowa.
