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.
|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.
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.
This formula's high volume of premium rubber helps Dura-Walk CWH retain its elastomeric and elongation properties, providing a flexible waterproofing membrane that won’t become brittle or crack like other materials.
Dura-Walk CWH contains 100% solids, so the material cures almost immediately upon application. The material cools and hardens quickly, minimizing downtime and speeding up the project timeline.
