ABOUT FILTERSLEEVE™

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.

Frequently Asked Questions

What is the purpose of FilterSleeve?

It provides a filter for coarse silt/fine sandy particles which would ordinarily enter an unprotected subsoil drain.

It acts as a soil stabiliser to help support and maintain the surrounding soil and reduce the breakdown of that soil structure.

How does FilterSleeve work?

Heavier and larger sand particles are trapped by the pores of the FilterSleeve and bridge the fabric pores (as opposed to lodging in them as would ordinarily be expected).

The larger, irregular sand particles provide a further surface which can trap smaller (clay and silt) particles within their irregularities.

The air void created between the sleeve and the corrugated pipe helps to equalize pressure across the FilterSleeve fabric and provides a space into which water can pass freely before entering the pipe.

FilterSleeve helps to stabilise the surrounding soil by recreating a microscopic soil structure around the sleeve.

Does FilterSleeve clog up?

No – assuming that the FilterSleeve is correctly installed and backfilled, then Massey University research suggests that the permeability of the filter fabric is not significantly reduced over long periods of service.

When should I use FilterSleeve?

To protect a punched subsoil drain that is being used in sand or sandy gravels. FilterSleeve is an inexpensive insurance against failure should the contractor not achieve a perfect installation – 5-6% more expensive overall.

When should I backfill around the pipe?

Backfill around a subsoil drain and FilterSleeve should be graded sand in compliance with Transit New Zealand specification TNZ f/5:2000. Feel free to call Cirtex 0800 247 839. Where sand is not readily or cheaply available, we suggest that a clay free, graded aggregate backfill such as builders mix, could be used subject to approval from a subsoil designer.
