Geotextile & Geogrids

What are Geotextiles & Geogrids?

Geotextiles and Geogrids help save millions of dollars every year by lowering life cycle costs and enhancing the performance of roadway and civil engineering projects. Geotextiles and Geogrids are easy to work with and install. Call or email us and we will help you pick the right geotextile or geogrid for your application.

Benefits

The use of Geotextiles and Geogrids in Civil Engineering projects improves sub grade/road base performance. They have been found to:

Maintain structural base
Reinforce soils
Improve subsurface drainage & filtration
Aid in erosion and sediment control
Enhance containment projects
Stabilize roadways & railroads

Types of Geotextiles

Woven
Non Woven
High Strength Woven

Functions of Geotextiles

Separation / Stabilization: Geotextiles separate dissimilar materials, preventing the loss or mixing of granular sub grade material into softer sub soils. They help maintain the structural component of flexible and rigid pavement sections.

Erosion Control: Often used under rip rap, geotextiles provide separation and filtration in erosion control applications.

Reinforcement: Geotextiles add strength to steepened slopes and temporary structures. They increase load bearing capacity and spread out compressive loads.

Sub Surface Drainage: Geotextiles aid in subsurface drainage and filtration.

Applications for Geotextiles

Separation / Stabilization of rigid and flexible pavements
Embankment Reinforcement & Stabilization
Vegetated & Wrapped Face Walls
Rip Rap Erosion Control
French Drain and Under Drains
Porous Pavement Detention / Retention Structures
Landfills & Waste Containment

Types of Geogrids

Polyester

Polyester, high tenacity multifilament yarns that are woven into a stable network. These high strength polyester yarns are coated with a PVC material.

Extruded polypropylene

Extruded polypropylene grid composed of two and three layers of high strength polypropylene, biaxially oriented. The layers are designed to accommodate find-grained, cohesive and non-cohesive fills as well as small sized random fill.

Structural Benefits of Geogrid

High Tensile Strength
High Junction Strength
High Mechanical Interlock
High Tensile Modulus
High Resistance

Functions of Geogrid

Soil Stabilization: When base material is compacted over geogrids (or geotextiles) the base material is “seated” locking the aggregate together in a fixed position.

Base Reinforcement & Confinement: Geogrids keep the fill material where it belongs and aids interlocking of granular base.

Stress Transfer: Geogrids do this by distributing applied loads over a greater area and thus reducing vertical pressure on the sub-grade.
