Subgrade Stabilization & Moisture Management Solutions

Mirafi is a brand of geotextile fabric used for separation, filtration, reinforcement, and drainage in civil construction projects. It is commonly placed between subgrade soil and aggregate layers to prevent fine particles from migrating upward into the base course, preserving structural integrity. Mirafi geotextiles are widely used in road construction, retaining walls, drainage systems, and erosion control applications.

Geotextile fabric for soil stabilization is a permeable synthetic textile installed between soil layers to separate, filter, reinforce, or drain. In stabilization applications, it prevents weak subgrade soils from pumping into aggregate base layers, maintaining the structural performance of roads and paved surfaces over time. Nonwoven geotextiles are frequently paired with cellular confinement systems for enhanced subgrade support.

A subgrade geotextile is placed directly on prepared subgrade soil before aggregate placement. It acts as a separator to keep native soils from contaminating the aggregate base, extending the design life of the pavement structure. It also provides filtration and limited reinforcement. Paired with geogrids or geocells, subgrade geotextiles form a complete system for stabilizing poor or soft soil conditions.

Geogrids are used in roadway construction (paved and unpaved), parking lots, retaining walls, bridge abutments, railroads, airports, wind farms, and mining access roads. Both biaxial and triaxial configurations are available — biaxial geogrids spread load in two directions, while triaxial geogrids distribute load radially, making them ideal for base reinforcement over soft or variable subgrade conditions.

Cellular confinement systems (geocells) are three-dimensional honeycomb-like structures filled with soil or aggregate that physically confine infill material, preventing lateral movement and erosion. Geogrids are flat tensile structures that interlock with aggregate to resist spreading under load. Geocells excel on slopes, driveways, and areas requiring erosion control, while geogrids are preferred for base reinforcement beneath roads and structural fills.
