The Alliance Remedial Land Drain Filter Sleeve is an ideal solution for contractors and DIY landscapers looking to extend the lifespan of their drainage systems by preventing sand and silt from clogging perforated pipes. By allowing water filtration while blocking fine debris, it maintains consistent flow and optimizes backfill performance, though installers should ensure the sleeve is fully secured across the entire length of the pipe to prevent gaps.

No, this sleeve is specifically designed to filter water entering through the perforations of drainage pipes.
The sleeve is made from a high-quality knitted geotextile designed for underground durability.
It acts as a filter that preserves the efficiency of your backfill, often reducing the requirement for specialized, expensive drainage aggregates.
Yes, the product is designed for easy, single-person application, sliding on like a sock.
Yes, this specific sleeve is sized for 60mm piping common in residential and commercial drainage.
Ensure the pipe is free of sharp plastic burrs at the cut ends which may catch on the fabric.
Ensure the pipe is properly bedded and backfill material does not contain large, sharp rocks that can pierce the geotextile.
To install, simply slide the knitted sleeve over the end of the perforated pipe and work it down the length of the pipe segment, ensuring it is taut and free of major folds. When joining two segments of pipe, ensure the sleeve overlaps at the connection point to maintain a continuous barrier against silt. The product is compatible with standard PVC, HDPE, steel, and aluminium drainage pipes. For maintenance, ensure that the trench backfill is placed gently around the sleeved pipe to avoid puncturing the geotextile fabric. If the ground is exceptionally rocky, consider a thin layer of bedding sand before placing the sleeved pipe to protect the material.
