Geosynthetic membranes

When Environmental Protection Matters

Aeramix is an industry leader in the application of geosynthetic liners with the capacity to deliver across multiple applications. Geomembranes are used for added structural support in water systems, to transport liquid, form barriers, protect liquids, separate liquids, prevent pollution or seepage of liquids, and to prevent contamination.

Geomembranes are typically made up of thin, continuous polymeric sheets. They can also be made from the impregnation of geotextiles with asphalt, elastomer or polymer sprays, or as multilayered bitumen geocomposites.

Our Geosynthetic services include:

  • Material procurement and supply
  • Civil works
  • Geosynthetic installation
  • Quality assurance compliance
  • Commissioning and leak detection
  • Repairs and maintenance

Geomembrane Repairs & Maintenance

Accidental tears and general deterioration of liners and covers can happen over time. In addition to the sourcing and installation of many different geomembranes, Aeramix provides a liner and cover repair and maintenance service Australia wide.

To access our geomembrane repair and maintenance service, you do not need to be a former or existing Aeramix customer.


High Density Polyethylene (HDPE) liners are the most widely used geomembrane for containment because of its durability and longevity.

  • HDPE’s chemical resistance makes it ideal for use as a landfill baseliner
  • HDPE comes in a range of thicknesses and roll widths.
  • HDPE liners can also be used in a variety of secondary containments, including pond linings,and water containment projects.
  • If treated with a UV stabiliser, HDPE can provide the UV resistance required for many years of outstanding UV resistant service.


LDPE (Low Density Polyethylene) and LLDPE (Linear Low Density Polyethylene)
liners are easy to fold and flexible in structure.

  • LDPE is widely used for manufacturing many domestic goods including bottles, plastic bags and computer hardware.
  • LLDPE is especially useful when working in a small space or tank, as it is easy to manipulate into different shapes and sizes.


Smooth geomembranes

HDPE Smooth geomembranes are used in projects demanding minimum permeability. They are extremely cost effective for a diverse range of applications including:

  • Aquaculture
  • Landfill (C&D and solid waste)
  • Animal waste containment
  • Power plants
  • Concrete tank liners.

Textured geomembranes

Textured HDPE improves the friction between the liner and the subgrade. It is available textured on one or both sides. The main benefit is that the texture makes the liner less slippery, therefore liners can be walked on safely. Textured HDPE is often specified for lining landfill.


Puraflex is a highly resistant polymeric geomembrane used for vapour barrier control.

  • Puraflex reduces the risk of contamination from hydrocarbon VOCs, toxic waste and natural and radioactive gases.
  • Comprehensive Chemical Resistance data for over 200 hydrocarbons and toxic chemical contaminants identified in Environmental Risk Assessments.
  • It’s specifically engineered for contaminated land, water resource and groundwater protection and secondary containment installations.
  • Puraflex provides an exceptional level of containment and steadfast protection for buildings, water resources and the environment.


Teranap is a geomembrane manufactured from SBS elastomeric bitumen, reinforced with a non-woven polyester geotextile. The underside, covered with a polyester film, is highly resistant to root penetration. The surface is coated with silica sand.

Teranap is a highly durable, environmentally conscious geomembrane.

  • Teranap is commonly used for underground installations and tanking.
  • It plays an integral role in hydraulics engineering: waterproofing of tanks, reservoirs,wastewater storage ponds, canals and dams.
  • It’s also used for the waterproofing of ‘cut-and-cover’ tunnels and pre-cast ducts.
