Geotextile Application Diagrams

Slope Erosion Control

Place a quality geotextile underneath the stone protection (rip rap) on slopes as shown. The fabric provides long-term confinement of cut slope or fill material.

Being constructed of soft and pliable needle-punched polyester, a quality geotextile will remain stable and functional for many years, in spite of potential exposure to the sun's ultraviolet rays and/or concentrated hydrocarbons, such as gasoline, diesel fuel, oil, or hydraulic fluid.

Landscaping

Place geotextile over soils around trees and shrubs, or in flower beds. It separates mulch materials from the underlying soils and aids in maintaining the landscape area.

Because it is made from tough polypropylene, a quality geotextile will not degrade if the sun's ultra-violet rays reach it. Its high puncture and tear resistance prevents rock or other cover material from pushing into the underlying soil. It will not float, yet has high permeability for water and gas exchange over 100% of its surface.

Mulching materials adhere well to a geotextile with a soft surface.

Pathway Construction

To eliminate the problem of gravel (or other pathway material, such as bark or shells) from mixing with underlying wet soils, place a geotextile on the sub-grade prior to installing the pathway material. This creates a consistent separation, keeping the surface free from mud and potholes.

The high strength of the continuous-filament, mechanically-bonded polypropylene will allow the pathway, driveway, or like surfaces to withstand stresses caused by occasional heavier traffic.

Putting Green Construction

Use a quality geotextile as a replacement for the usual 2" course sand layer between the greens mix and the gravel drainfield. The fabric will eliminate downward migration of the mix into the gravel and the subsequent reduction of water flow from the green.

A geotextile with high water permeability and highly engineered uniform density and ESO (ASO) make an ideal fabric for this use. It will not rot in the soil-water environment.  Its horizontal (planar) flow characteristic moves excess water horizontally out to the sides.
