FilterSleeve is a tested and proven solution for protecting subsoil drains from sedimentation. Readily available, cost effective and proven to perform, FilterSleeve is your first choice for protecting perforated pipe subsoil drains.
Manufactured as a three dimensional knitted fabric, FilterSleeve comes in a seamless length to fit a large range of pipe sizes.
It works by trapping the sand particles and assisting the formation of a soil filter around the pipe. This results in greatly improved permeability surrounding the pipe, giving greater flow of water into the drain system and almost total reduction of sediments settling in and reducing the drainage flow.
FilterSleeve is manufactured in New Zealand to strict quality control procedures, as the performance of the product is dependant on the accurate formation of the knit structure and pore sizes. Insist on Cirtex® FilterSleeve for proven results.
Fit to the pipeline on site using Preloaded Applicators or purchase from leading pipe manufacturers pre-installed.
