Non-curing Rubberized Bitumen Waterproof Coating polymer rubber modifiers, and specialized plasticizers under high-temperature processing, forming a black, viscoelastic mastic that remains non-hardening throughout its service life.
Unlike conventional waterproof coatings that cure into rigid films, this material maintains permanent creep and self-healing properties, allowing it to continuously adapt to structural movement, vibration, and settlement. It is specifically designed as a key base-layer material for composite waterproofing systems in underground structures, tunnels, and large infrastructure projects.
When applied with SBS, APP, or self-adhesive waterproof membranes, it forms a fully bonded composite waterproof system. The material fills micro-cracks, pores, and surface irregularities, eliminating water channeling between layers and significantly improving waterproof reliability.
Its excellent adhesion performance under both dry and wet conditions ensures full bonding with concrete substrates and waterproof membranes, making it a preferred solution for complex underground engineering environments.
Key Features & Benefits
When waterproofing systems face challenges from structural movement, cracks, and water migration, QINGYUAN Non-Curing Rubber Modified Bitumen Coating provides a flexible and reliable solution with self-healing and long-lasting waterproof performance.
Permanent flexibility allows the coating to continuously deform with substrate movement without cracking or losing waterproof performance.
Excellent self-healing ability automatically seals minor damage and punctures, reducing leakage risks during long-term service.
Strong adhesion on dry and damp substrates creates a fully bonded waterproof layer and prevents water migration.
High solid content and solvent-free formulation provide safe application with excellent environmental performance.
Creates a composite waterproof system when combined with SBS, APP, or self-adhesive membranes for enhanced protection.
No curing waiting time allows immediate membrane installation after coating, improving construction efficiency.
Excellent resistance to heat, low temperatures, acids, alkalis, and underground environments ensures long-term durability.
Superior stress relaxation performance absorbs structural deformation caused by settlement, vibration, and temperature changes.
Ideal for underground structures, tunnels, roofs, bridges, and large-scale waterproofing projects requiring reliable protection.

Standard Construction Process
Professional installation methods ensure strong bonding, excellent flexibility, and reliable composite waterproof protection for demanding construction projects.
Base Surface Preparation
Remove dust, loose materials, and sharp objects from the substrate. Repair cracks and uneven areas to ensure a clean and stable surface.
Detail Reinforcement Treatment
Apply additional non-curing coating to critical areas such as corners, pipe penetrations, expansion joints, and construction joints for enhanced protection.
Material Heating & Preparation
Heat the coating using specialized equipment to achieve the required application temperature while maintaining uniform material performance.
Large Area Coating Application
Apply the molten coating evenly by scraping or spraying according to the designed thickness, ensuring complete coverage without exposed substrate areas.
Membrane Composite Installation
Install SBS, APP, or self-adhesive waterproof membranes while the coating remains in a molten state, creating a strong integrated waterproof system.
Joint Sealing & Final Inspection
Seal membrane overlaps, complete waterproof details, and perform water testing after installation to ensure the system meets waterproofing requirements.
