Walkway Water Barrier



The Walkway Water Barrier is produced in the USA and is composed entirely of high-density polyethylene (HDPE). It is offered in a range of sizes and thicknesses to accommodate various installation requirements. The available thicknesses vary from 30 mil to 100 mil, with "mil" denoting one-thousandth of an inch. Roll heights are available from 18 inches to 60 inches, with most rolls being 100 feet in length and a select few available in 80 feet.

Key Features:
Durability: The barrier is waterproof, UV resistant, and non-biodegradable, ensuring long-lasting performance.
Resistance: It is impervious to damage from insects and rodents and resistant to rot and mildew, making it ideal for outdoor use.
Integration: For larger areas, multiple rolls can be joined using double-sided HDPE seam tape, providing a continuous, effective barrier.

This product is readily available from our warehouse in Kansas City, MO, and typically ships within one business day to quickly meet your project needs.

Material Thickness:
30 mil = 1/32”
40 mil = 3/64”
60 mil = 1/16”
80 mil = 5/64”
100 mil = 3/32”

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

We are also unable to provide custom roll lengths.
