Flexible Trough Drain Liner



Our Flexible Trough Drain Liner is constructed from high-density polyethylene (HDPE), a robust waterproof material designed to meet the demanding conditions of any job site. This liner excels in durability, being both puncture and tear-resistant, yet it remains flexible enough for easy handling and installation.

The liner is primarily used within trenches that have been excavated for drainage purposes. To install, simply lay the liner in the trench and cover it with rocks to ensure it stays in place. For larger projects, where multiple liner sections are needed, they can be overlaid and joined using our HDPE double-sided seam tape (sold separately).

Material: High-density polyethylene (HDPE), valued for its toughness and flexibility.
Width Options: Available in widths ranging from 18 inches to 60 inches.
Thickness Options: Available in thicknesses ranging from 40 mil to 80 mil.
Roll Length: Comes in rolls of 100 feet each.
Origin: Manufactured in the USA.

Ideal for construction, landscaping, or agricultural applications, this product provides a reliable solution for managing water flow and controlling erosion effectively.

Material Thickness:
40 mil = 3/64”
60 mil = 1/16”
80 mil = 5/64”

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

We are also unable to provide custom roll lengths.
