Product Description:

The GTDSupply shower waterproofing membrane is a high polymer polyethylene polypropylene tile underlayment designed to deliver exceptional waterproofing and vapor control for modern construction and renovation projects. At 20 mil thick and 1 m wide, this premium membrane provides a reliable and durable barrier against water infiltration, helping to protect substrates and extend the lifespan of tile installations in moisture-prone environments.

Built with nonwoven polypropylene fabric bonded to both sides, this membrane ensures superior adhesion with thin-set mortar, creating a strong mechanical bond between the substrate and the finished tile surface. Acting as an effective uncoupling layer, it binds the substrate below and tile layer above while helping to absorb movement and reduce the risk of cracks, making it ideal for both new builds and renovation applications.

Engineered for high-performance waterproofing, this membrane features a low permeability rating that provides excellent vapor protection in showers, steam rooms, and other high humidity areas. It prevents water vapor from spreading into adjacent rooms while protecting walls and floors from long-term moisture damage. Its versatility makes it suitable for residential living spaces as well as commercial environments such as restaurants, galleries, and shopping centers.

Installation is simple and efficient using standard thin-set mortar adhesive. Once the membrane is properly installed and cured, it creates a seamless waterproof surface ready for tile application. It supports a wide variety of finishes including ceramic, porcelain, travertine, limestone, marble, agglomerates, glass tiles, and natural stone, allowing for complete design flexibility.

Whether used in showers, bathrooms, kitchens, balconies, bathtub surrounds, or steam rooms, the GTDSupply waterproofing membrane delivers a dependable and long-lasting solution. Its combination of high polymer strength, waterproofing performance, and ease of installation makes it a trusted choice for contractors and homeowners seeking professional-grade results and superior protection against water damage.
