RTA Grade Filter Sock

Convic Australia offers the RTA Grade Filter Sock, designed to enhance the performance and longevity of your agi pipes, also known as ag pipes, agg lines, drainage pipes, and soakage drains. This high-quality, Australian-made filter sock is engineered to meet the stringent standards set by the Roads and Traffic Authority (RTA), ensuring reliable performance in various drainage applications.


What is a Filter Sock?

A filter sock is a crucial accessory for agi pipes, acting as a barrier to prevent fine soil particles, sand, and debris from entering the pipe and causing blockages. By maintaining optimal water flow and preventing sediment build-up, the filter sock enhances the efficiency and lifespan of your drainage system.


Features and Benefits

  • Advanced Filtration: The unique three-dimensional, high-flow filter provides excellent filtration with over twenty years of proven performance.
  • Inert and Durable: Made of tough, knitted polyester fibers, the filter sock is more inert and resistant to degradation than nylon and organic materials, ensuring longevity and reliability.
  • Strong Construction: The knitted polyester is a continuous sleeve running the entire length of the tubing, which does not require bindings, glue, or ultrasonic sealing, thus resisting tearing and damage during handling, shipping, and installation.
  • Safe and Clean: No sharp fibers to cause damage during manual handling and no dust particles during factory fitting, making it safe for workers and drainage machinery.
  • Lightweight: The filter sock rolls can be easily lifted and carried manually, even when wet.
  • Long Lifespan: Exhibits an equal lifespan to that of plastic drainage pipes once installed in the ground.
  • Easy Installation: Shipped in convenient roll sizes, the filter sock can be fitted onto perforated drainage pipes in one integrated operation, either at the pipe manufacturers or in the field where the system is being installed.



The RTA Grade Filter Sock is ideal for a variety of drainage applications, including:

  • Agricultural Drainage: Prevents soil and debris from clogging agi pipes in fields and gardens.
  • Residential Landscaping: Maintains efficient drainage in garden beds, lawns, and retaining walls.
  • Commercial Drainage Systems: Enhances the performance of drainage systems in commercial properties and public spaces.
  • Civil Engineering Projects: Meets the rigorous demands of road construction and other heavy-duty infrastructure projects.
