Texcel geotextiles, which are manufactured in Australia, are supported by 25 years of research, development and testing. They are highly resistant to abrasion and UV degradation and provide superior filtration for coastal applications and excellent cushioning for landfill applications. Texcel geotextiles also have high elongation properties minimising installation damage and ensuring effective soil contact, interaction and stability.

Geofabrics provide a high level of technical support to make sure your project is implemented effectively and efficiently using the correct type and grade of geotextile.

Continuous research and development is carried out at the 'Geosynthetic Centre of Excellence’ on the Gold Coast in Queensland. Including protection geotetxile testing apparatus and a full scale rock drop apparatus to simulate on-site revetment performance.

Functions

Filtration

Texcel restricts the migration of fine soil particles from a soil mass while remaining permeable to water movement at a rate at least equivalent to the permeability of the retained soil.

Drainage

To allow water to flow through or within the plane of the geotextile, allowing the dissipation of pore water pressure which can have a detrimental effect on engineering structures.

Separation

To separate and prevent two distinct soils or different materials from intermixing, thereby maintaining the performance of the individual materials.

Protection

To prevent damage to plastic liners used in landfills, by limiting deformation and puncturing potential.

Shoreline Protection

To prevent erosion of coastal and shoreline areas by retaining sand and other fines while being subject to continuous wave, tidal and other wave motions. The Texcel range of geotextiles are also used to create our ELCOROCK shoreline protection system.

Applications

Revetments

The loss of soil from behind a revetment will have an adverse effect on the stability and effectiveness of any revetment. Due to their ease of construction and low cost, geotextiles have replaced granular filters in revetment applications; with the nonwoven geotextile mimicking a natural graded filter. 

The Texcel R range of polyester geotextiles are designed to resist impact damage and to retain soil particles without significantly reducing the permeability requirements of the revetment. A selection chart is available to help engineers select the right grade of coastal geotextile for their project.

Waste & Containment Structures

Heavyweight Texcel polypropylene geotextiles have a unique staple fibre blend and an inbuilt flexibility designed to protect plastic liners in landfill, waste and containment systems. They are used to prevent damage to impermeable liners - the design of the liner system needs to limit the chance of punctures during installation and reduce the risk of long term stress cracking of the geomembrane.

Research has shown that Texcel nonwoven staple fibre geotextiles can significantly reduce forces placed on impermeable liners, protecting them in both the short and long term.

Sand Containment Structures

Texcel RP nonwoven staple fibre geotextiles are used in the manufacture of our Elcorcok system, which is successfully used for short and long term applications in sea walls and revetments, groynes, breakwaters and emergency containment. Their development has led to them being used in artificial reefs for beach erosion protection, encouragement of sea-life habitat and surf improvement.

Advantages

  • Manufactured in Australia to the highest quality standards, and allowing full traceability of every roll produced.
  • Can be manufactured to suit project requirements and chemical compatibility.
  • Very high abrasion and UV resistance as well as consistent mechanical and hydraulic performance.
  • Available in custom grades and roll lengths.
  • Supported by extensive research and development programs which are carried out at the 'Geosynthetic Centre of Excellence’ located on the Gold Coast in Queensland.

Installation

Placement procedures should be in accordance with the project specifications. This will include compliance with stripping, grubbing and final trim, grading requirements, cover material specifications, lift thicknesses and equipment requirements. Other considerations including placement in wind and underwater should be addressed in construction or site specific specifications.

Performance considerations such as removal of wrinkles and folds or pre-tensioning the geotextile should be addressed as specified. For placement of 6m wide rolls a Geofabrics spreader bar is recommended.
