Ground Reinforcement & Subgrade Stabilization Services

A subgrade is the prepared native soil or improved ground layer that supports the pavement, roadway, slab, or structural section above it. Its purpose is to provide a stable foundation that distributes loads and limits settlement, rutting, and deformation. When subgrade soils are weak or wet, reinforcement products such as geogrids or geotextiles can improve performance and reduce aggregate requirements.

The subgrade is the existing or prepared soil foundation at the bottom of the pavement or structural section. The subbase is an engineered layer, often aggregate, placed above the subgrade to improve support, drainage, and load distribution. Geosynthetics may be installed between these layers to separate materials, reinforce the section, and improve long-term performance.

Ground reinforcement is commonly used when soils are soft, wet, unstable, or unable to support construction traffic and final design loads without excessive aggregate. It is also valuable for roadways, haul roads, parking areas, building pads, and infrastructure projects where reducing excavation, aggregate thickness, or delays can create meaningful cost savings.

Common subgrade stabilization products include geogrids, geotextiles, soil stabilization materials, drainage products, and related geosynthetics. Coleman Moore Company supplies solutions from leading manufacturers such as Tensar and Solmax and helps evaluate which product best fits the soil condition, load requirements, constructability needs, and project budget.

Dynamic Cone Penetrometer, or DCP, testing helps estimate in-place soil strength quickly on site. Coleman Moore Company can use DCP results with conversion to CBR values to better understand weak subgrade conditions. This information supports more informed material selection, pavement section optimization, and cost-benefit comparisons before construction decisions are finalized.

Yes. Properly selected geogrids and geotextiles can improve load distribution and confinement, which may reduce the amount of aggregate needed for a roadway or working platform. Coleman Moore Company evaluates performance requirements and budget considerations to recommend solutions that can save time and money while still meeting project specifications.

Yes. Coleman Moore Company provides strategic site evaluations, brand and product analysis, cost-benefit analysis, design assistance, and installation consultation. The team also works with manufacturer resources and tools such as Tensar Plus design software to help optimize aggregate thickness, pavement sections, and geosynthetic product selection.

Coleman Moore Company supports roadway, civil, environmental, and infrastructure projects for contractors, engineers, municipalities, developers, architects, DOTs, DNRs, and regulatory agencies. Typical applications include poor subgrade stabilization, paved and unpaved roads, drainage challenges, retaining structures, erosion control, sediment control, and site stabilization needs.
