Our product lines include HDPE self-adhesive waterproof membrane, PVC membrane, EPDM rubber membrane, TPO roofing membrane, bitumen membrane, polyurethane waterproof coating, acrylic coating, cementitious coating, polyurea coating, and professional accessories.

Customers can source membrane rolls, liquid coatings, fasteners, tapes, prefabricated corners, and project-specific waterproofing accessories from one supplier. With 62 production lines and 4 manufacturing bases, Hongyuan supports contractors, distributors, and OEM buyers with stable quality, factory-direct pricing, and technical guidance for material selection.

Waterproof membrane series

Waterproof membranes are suitable for projects that require consistent thickness, high tensile strength, predictable lap treatment, and efficient coverage of large areas. HDPE self-adhesive waterproof membrane is often used for below-grade structures, basements, tunnels, and pre-applied concrete waterproofing. PVC, TPO, and EPDM membranes are widely used in roofing and exposed applications where flexibility, weather resistance, and long-term dimensional stability matter. Bitumen membranes remain a practical option for many roofing, foundation, and civil engineering projects that need strong adhesion and proven site performance.

Liquid waterproof coating series

Liquid-applied waterproof coatings help solve complex detailing conditions where sheet membranes are difficult to install. Polyurethane waterproof coating offers elasticity and crack-bridging performance for roofs, balconies, wet rooms, and repair areas. Acrylic coatings are useful for exposed roof maintenance and reflective coating systems. Cementitious waterproof coating is commonly used on concrete substrates, water tanks, bathrooms, basements, and masonry surfaces. Polyurea and bitumen coating options can be selected for higher-performance or specialized applications.

How to choose waterproofing materials

• Use HDPE pre-applied membrane for below-grade concrete and water-locking requirements.
• Use PVC, TPO, or EPDM membrane for exposed roofing systems and mechanical fixing.
• Use polyurethane coating for flexible, seamless waterproofing around complex details.
• Use cementitious coating for concrete, masonry, wet rooms, and water-facing surfaces.

Selection should consider substrate condition, exposure level, climate, installation method, project schedule, budget, and service-life expectations. Hongyuan can provide product specifications, packaging information, project photos, technical data, and quotation support so buyers can compare membrane and coating systems before placing an order.

For distributors and contractors, accessories are part of the waterproofing system rather than optional extras. Vapor retarder tape, metal strips, fasteners, prefabricated internal corners, prefabricated external corners, and reinforcement materials help improve detail treatment and reduce leakage risk. Hongyuan supplies these supporting materials together with membranes and coatings, making procurement simpler for export customers and project teams.

Before purchasing waterproofing materials, buyers often compare thickness, roll size, reinforcement type, exposed or non-exposed use, installation temperature, lap method, curing time, packaging, and container loading quantity. Hongyuan helps customers review these details early so the selected product matches the jobsite conditions and import plan. This is especially important for large roofing projects, basement waterproofing, tunnel construction, bridge decks, and municipal engineering work where delayed material decisions can affect the entire schedule.

We welcome inquiries for standard products, bulk orders, and customized waterproofing solutions. Share your application area, target specification, project location, and estimated quantity, and our team will recommend suitable waterproof membrane, waterproof coating, and accessory combinations for your market.

Our product team can also help compare sheet membrane systems with liquid-applied coating systems when a project has multiple waterproofing zones. This makes it easier to combine roof, basement, wet-area, and detail waterproofing materials under one purchasing plan.
