Unprotected subsurface drainage systems often fail when sand and soil particles enter the perforated pipes. Infiltration of unwanted soil particles restricts and eventually prevents the flow of water through pipes, which leads to overflows, waterlogged areas, soil erosion, among other issues.
Since the 1970’s, our 100% polyester, circular-knit Drainage Filter Socks™ have protected subsurface drainage systems from failure due to sediment buildup. Our Drainage Filter Socks™ will keep your pipes running like new!
Our Drainage Filters are applied to the outside of perforated drainage pipes like pulling on a Sock™. Once installed, the geotextile allows water to pass into the pipe, but keeps out the sand, silt, and backfill sediment that can clog pipes and lead to drainage system failure.
When applied to the outside of corrugated pipes, our Drainage Filter Sock™ spans the valleys of the corrugations, keeping soil away from the perforations. In doing so, the thousands of small, uniform filter openings increase the inlet area for water to reach the perforations of the pipe. Since the perforations in the pipe are then left unobstructed by soil particles, the groundwater freely enters the tubing as intended, guaranteeing optimal drainage.
The opening size of our Drainage Filter Sock™ is specifically engineered to allow very fine (colloidal) soil particles to pass through the filter and into the pipe – only to be flushed away with the water moving through the pipe. This creates void spaces in the larger soil particles that remain trapped around the geotextile, which increases the permeability of the soil immediately surrounding the pipe and improves drainage efficiency.
See what sets our Drainage Filter Sock™ apart from the competition:
Polyester is a man-made fiber with a high strength-to-weight ratio. When manufactured with our circular knitting technology, the result is a durable, lightweight geotextile that resists abrasion and tearing. Polyester is also naturally inert to most acids and chemicals found in soil, which prolongs the life of the filter and drainage system.
All of our Sock™ filters feature a tubular knit construction and are installed on pipes like pulling on a sock. Other geotextiles, which are not specifically designed to be used as pipe envelope filters, may require sewing or sonic welding to be installed on the pipe.
Our Sock™ filters are available in black fabrics to increase resistance to UV radiation. As a precaution, we do not recommend unprotected outdoor storage of white fabrics for more than 60 days or black fabrics for more than 90 days. In extreme conditions, fabric degradation may occur sooner.
Every Sock™ filter is designed with a specific and uniform opening size across its surface to fit a particular size of pipe. This provides deliberate and consistent levels of filtration and flow rates over the length of the pipe, especially compared to the randomly placed fibers in nonwoven geotextiles.
Our Sock™ filters come in a range of sizes, for 2″ to 48″ diameter pipes (50 mm to 1200 mm), and are suitable for any drainage project, big or small. Our Drain-Sleeve® filters for DIY drainage are available in the most common pipe sizes ranging from 3″ to 6″ diameters (75 mm to 150 mm).
While our Sock™ filters are most effective when used with corrugated drainage pipes, they are designed to be compatible with a wide variety of perforated drainage pipes, including PVC, aluminum, and steel.
Our circular knitting technology produces completely seamless, tubular filter socks. The lack of seams reduces the risk of snags and tears during normal handling and installation.
If you are a DIY-enthusiast looking to tackle your own drainage project, you can find our patented Drain-Sleeve® products in major home improvement stores throughout the United States and Canada, including Home Depot (US/Canada) and Lowe’s. You can also visit our DIY page to learn more.
