Slot Drain Channel Liner



Our Slot Drain Channel Liner is composed from high-density polyethylene (HDPE), a waterproof and durable material engineered to endure the harsh conditions of construction sites. It is designed to resist punctures and tears, while still offering the flexibility needed for easy deployment. It is commonly used in slot drain systems. For extensive drainage configurations, liner sections can be overlapped and connected using our HDPE double-sided seam tape (sold separately).

Material: High-density polyethylene (HDPE), known for its robustness and flexibility.
Width Options: Ranges from 18 inches to 60 inches.
Thickness Options: Available in thicknesses from 40 mil to 60 mil.
Roll Length: Comes in 100-foot lengths (80 foot length for certain roll widths)
Origin: Manufactured in the USA.

Designed specifically for slot drain applications, this liner ensures efficient water management, protecting infrastructure from water-related damage.

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.
