Dura-Walk® CWH

Highly Sag Resistant
High-Performance Formula
Quick Curing

Dura-Walk CWH is a hot-applied, seamless waterproofing membrane. This 100 % solid rubberized, asphalt-based formula is fluid-applied to form a continuously-adhered waterproofing system over a variety of concrete substrates. Apply this flexible, high-build material to surfaces requiring a waterproofing layer before adding a covering (such as tile, concrete, pavers, or vegetative roof system). Dura-Walk CWH is a versatile waterproofing system, ideal for parking structures, walkways and terraces, roofs, and other instances requiring a monolithic waterproofing membrane.

Product Specifications

Method	Description
Hot-Applied	Apply Dura-Walk CWH at 380-400º F (193.3-204.4º C) to the prepared surface by pouring or pumping from the melter at a minimum of 115 mils (0.115”) thick. Distribute the material evenly on the deck surface using a flat blade squeegee, approximately 18”-wide and 3/16 - 1/16” thick (45 cm wide and 0.48 – 0.16 cm thick). If bubbles or other outgassing appear, apply additional material. After base layer is applied, immediately roll in HPR ® Polyscrim Plus, or approved equal reinforcement, into the hot Dura-Walk CWH. When reinforcement is embedded, apply top layer of Dura-Walk CWH at least 100 mils (0.10”) thick. The total system height should be at least 215 mils (0.215”), but may be higher. Dura-Walk CWH system should be covered as soon as possible with either polyethylene sheeting, protection boards, roll roofing, pavers, or asphalt-saturated sheets. This protects the Dura-Walk CWH system from punctures, abrasions, and UV exposure. See Application Guide for general application guidelines, and project specifications for specific application instructions. Contact Garland's Technical Department with questions.

Features

Highly Sag Resistant

Dura-Walk CWH is easy to build into a thick, durable system – even while taking fewer steps than others. This formula flows easily into cracks and crevasses, bridging cracks up to 1/8” wide (as opposed to other formulas that bridge cracks up to only 1/16”). Dura-Walk CWH applies easily, and new coats can be applied to previous coats without rigorous preparation.
