Flexible Channel Drain Liner



Our Flexible Channel Drain Liner is crafted from high-density polyethylene (HDPE), a durable waterproof material renowned for its ruggedness and ability to endure the harsh conditions of a job site. This liner is specially designed to resist punctures and tears, yet it maintains enough flexibility to be easily installed.

The liner is typically laid within an excavated trench. Once in place, rocks can be directly laid on top to secure the liner. For extensive channel projects, multiple liner sections can be overlapped and securely connected using our HDPE double-sided seam tape (available separately).

Material: High-density polyethylene (HDPE), known for its durability and flexibility.
Available Widths: Ranges from 18 inches to 60 inches.
Thickness Options: Ranges from 40 mil to 60 mil.
Roll Length: Each roll is 100 feet long.
Origin: Proudly made in the USA.

This liner is an ideal solution for projects requiring reliable, long-lasting water management systems. Whether for construction, landscaping, or agricultural uses, the Flexible Channel Drain Liner offers a dependable and effective way to manage water flow and prevent soil erosion.

Material Thickness:
40 mil = 3/64”
60 mil = 1/16”

Please Note: The widest rolls that we offer in HDPE are 60” (5ft).

We are also unable to provide custom roll lengths.
