The standard Puraflex Industries geotextile is typically used in ground stabilisation (between the sub-base and subgrade) and around drainage materials to enhance the performance and design life of the granular layers by providing the filtration and separation functions.

Preventing granular materials and soils from mixing
When stone is placed on top of a soft subgrade, the load often causes intermixing of the two layers. This results in the contamination of the stone layer which can lead to a loss of bearing strength, causing the surface to rut and deformation at the sub-base/subgrade interface to occur.

Puraflex Industries geotextiles provide an effective solution to this problem allowing the construction of a stable granular layer over soft foundation soils.

Preventing fines entering into drainage media
Standard Puraflex Industries geotextiles are perfect for preventing fines entering into granular or geosynthetic drains, such as open geocellular units.

Puraflex Industries filters/separators are used extensively in the construction of:

  • Paved and unpaved roads
  • Railways
  • Car parks and hardstandings
  • Cycleways and footpaths
  • SuDS installations
  • Green roofs

Non Woven Geotextile

Although non-woven geotextile has a lower tensile strength than the woven type, it still offers great strength, durability and excellent drainage properties. Non-woven geotextile is a felt-like fabric made by thermally bonding polypropylene or a mixture of polypropylene and polyester fibres and then finishing using needle punching, calendering and other methods. This type of geotextile fabric is easier to cut, has a high water permeability rate and does not lose strength over time, in the same way as the woven fabric does, when used below ground. This makes it ideal for use beneath driveways and roads and in land and stormwater drainage systems, where long-term ground stabilisation and filtration is required. Nonwoven Geotextiles are needle punched to form a strong fabric that retains its dimensional stability and is resistant to damage from construction stresses.Nonwoven Geotextiles are available in varying strengths and thicknesses to ensure appropriate material selection for your project. Custom roll sizes are also available. Nonwoven Geotextiles have a wide range of applications in civil environmental engineering and construction projects.

Their uses include:
  • Filtration of soils in drainage applications by retaining soil particles while allowing for the free flow of water
  • Separation and stabilization in road and railway construction
  • Prevention of soil movement in erosion control measures 4. Cushioning and protection in many containment projects

Woven Geotextile

Woven Geotextile are made from weaving monofilament, multifilament, or slit film yarns. Weaving is a process by which interlocking yarn is to make Woven Geotextile. Slit film tape Woven Geotextiles are commonly used for sediment control, i.e. Slit fence, and road stabilization applications. Though the flat tape slit film yarns are quite strong and can be used for reinforcement application also. Monofilament Woven Geotextiles have better permeability, making them suitable for certain drainage applications. High strength Multifilament Woven Geotextiles is primarily used in reinforcement applications. Wove geotextile is also used for making Geobags for Bund construction for Seashore reclamation, Bank protection, to prevent bed erosion and relevant applications. For making cost-effective solutions, we can also use of Non-woven Geotextile bag is recommended along with outer Woven Geotextile bag for Construction. Mainly Woven Geotextiles are made up from Polypropylene and/or Polyester.
