Westwood Usa

WestWood USA is a building materials manufacturer specializing in PMMA-based liquid-applied roofing, waterproofing, and trafficable surface systems for commercial and institutional construction. We design and manufacture cold liquid-applied membrane systems, fully and partially reinforced, that deliver seamless, monolithic waterproofing across complex building envelope conditions. WestWood systems are rapid-curing, cold applied, and fully bonded, supporting safer jobsites, faster installation, and long-term durability. Our PMMA waterproofing and roofing systems are engineered for demanding applications where traditional membranes fall short, including complex detailing, high-movement substrates, tight construction schedules, and high-traffic exposure. WestWood solutions are proven, cost-effective alternatives to conventional roofing, sheet membranes, and hot-applied systems. Key WestWood applications include: • Liquid-applied roofing systems • PMMA waterproofing membranes for podium decks, plazas, and terraces • Balcony, walkway, and pedestrian traffic systems • Vehicular traffic systems for parking decks, ramps, and drive lanes • Integrated flashing, penetration, and transition detailing • Hybrid reinforced sheet membrane and PMMA systems WestWood membranes are self-adhering, self-terminating, and monolithic, eliminating seams, laps, pitch pockets, and vulnerable terminations, resulting in low-maintenance, long-term waterproofing performance. At WestWood USA, we combine advanced material science, PMMA technology, and real-world field experience to support architects, specifiers, consultants, and contractors with high-performance building envelope solutions designed to install quickly and perform reliably.
