Polymer Cement-based Elastic Waterproof Membrane

Polymer-Cement-Based Elastic Waterproofing Membrane consists of a base coat and a top coat, forming a high-performance waterproofing material that combines flexibility with stability. The base coat is a dry powder product that requires only water mixing during application. The top coat features a two-component formulation comprising liquid and powder components, allowing performance adjustments to meet project requirements. Polymer-Cement-Based Elastic Waterproofing Membrane is categorized into Type I and Type II based on application environments. Type I is primarily suited for areas with significant movement, such as roofs, balconies, and expansion joints, where prolonged immersion is not expected. Type II is designed for structures with minimal movement but constant immersion, including basements, kitchens, bathrooms, swimming pools, and tunnels. The substrate must be flat, solid, and free of structural defects like hollows, delamination, or cracks. Surfaces should be clean of dust, oil, or other contaminants that could compromise adhesion, ensuring the waterproofing layer's bond strength and overall stability. The elongation at break of polymer-modified cementitious elastic waterproofing membranes can be adjusted within the range of 80%-300%. This allows the membrane to effectively accommodate deformation stresses caused by building drying shrinkage and temperature variations without cracking, making it an ideal waterproofing solution for diverse and complex construction environments.

Regarding construction performance, polymer-cement-based elastic waterproof membranes are cold-applied materials that can be directly applied to damp substrates. Their simple and convenient application method suits diverse environments. Once cured, the material forms a highly cohesive, seamless waterproof layer through continuous coating, maintaining impermeability under 30m water pressure and demonstrating exceptional waterproofing performance. Additionally, this material exhibits outstanding aging resistance, making it suitable for long-term waterproofing in exposed roof applications. It remains unaffected by sunlight, temperature fluctuations, or climatic conditions, ensuring consistent performance over time. As a water-based, environmentally friendly material, polymer-modified cementitious elastic waterproofing membranes are non-toxic, pollution-free, and contain no volatile organic solvents, ensuring safety for both workers and the environment. Its strong adhesion outperforms ordinary mortar by 6-9 times on various substrates, significantly enhancing the stability and reliability of the waterproofing layer. With superior elongation, durability, and eco-friendly properties, polymer-modified cementitious elastic waterproofing membranes are widely applicable in new construction and renovation projects, serving as a key material in modern waterproofing systems.
