Geotextiles - Woven & Nonwoven
Geosynthetic Systems offers a wide variety of soil stabilization geotextile products in countless sizes which allow you to select the most cost-effective geotextile for your particular application and site conditions. Generally speaking, there are four basic functions of geotextiles:
- Separation/Stabilzation
- Drainage
- Filtration
- Reinforcement
Separation & StabilizationNumerous case studies have proven that use of geotextiles in load bearing applications (roads, parking lots, construction access, etc.) show improved resistance to deformation. This means increased service life for asphalt or concrete surfaces and resistance to rutting on unpaved roads. In any application, roadway performance is improved.
In addition to maintenance savings, geotextiles save cost by reducing aggregate depth and preserving the aggregate. FiltrationFiltration functions to restrict the migration of fine soil particles from a soil mass while remaining permeable to water movement at least greater than, or equivalent to permeability of the protected soil.
Drainage: Subgrade Dewatering, Road Base Drainage &
Structure DrainageA high groundwater table can, and often does,
interfere with the stability of subgrade soils.
For instance, some clay soils can swell or shrink
as their water content increases or decreases,
respectively. Also, most soils are considerably
weaker when they have high water contents or
have not been drained prior to loading. This
means that weather-related or seasonal
fluctuations in groundwater levels can adversely
affect permanent structures founded on
undrained soils.
Draining saturated soils can increase their
strength and stability.
Reinforcement
To meet the demanding range of site requirements for
reinforcement projects, medium- or high-strength geotextiles
of polypropylene composition are designed to provide
versatility, variety and durable performance.
Medium- or high-strength geotextiles are available for reinforced work platforms and similar applications. Tensile strength and tensile modulus vary to meet specifi c requirements. High-tenacity woven geotextiles are available for long-term reinforcement in critical performance structures. High tensile strength and modulus contribute to soil
structure reinforcement. Additionally, low strain under load minimizes potential for creep deformation. Application features:
- Distributes soil cover stresses
- Maintains reinforcing integrity
- Installs easily
- Cost effective
