Creep-type Self-healing Non-curing Rubber Asphalt Waterproof Coating

Product Overview

Non-curing rubber asphalt waterproof coating is an innovative creep-modified waterproof material formulated with high-quality petroleum asphalt as the base, reinforced by rubber powder, functional polymer modifiers, and proprietary additives via precision production processes.

Its defining feature is permanent viscoelastic paste state throughout its service life, eliminating curing-induced cracking and performance degradation common in traditional waterproof materials. As the industry-leading waterproofing solution, it can be applied as a standalone coating or combined with SBS/self-adhesive waterproof membranes to form a monolithic "skin-like" waterproof system, meeting the stringent requirements of National Class I Waterproof Grade.

Construction Advantages of Non-curing Rubber Asphalt Waterproof Coating

I. Construction Efficiency Advantages

1. Simplified processes, construction period shortened by over 30%

• No need for substrate drying treatment, construction can be carried out as long as there is no standing water, eliminating the waiting period (usually 7~14 days) required for traditional waterproof materials to meet substrate moisture content standards
• No curing required after coating application, waterproof membrane laying can be completed within 3 minutes. Composite system construction can be finished in a single day, reducing the construction period by at least 50% compared with the traditional SBS membrane + cold primer process
• Mechanical spraying construction efficiency reaches 10001500 ㎡/day, 34 times that of traditional membrane construction, with particularly significant advantages for large-area projects

2. Strong scenario adaptability

• Can be directly applied on damp and uneven substrates, eliminating the need for large-scale substrate leveling treatment and reducing base treatment costs
• Detailed nodes such as internal and external corners, pipe roots, and deformation joints can be directly formed by scraping, no additional membrane cutting is required, reducing construction difficulty
• Normal construction can be carried out in winter, and operation can be performed without special insulation measures in environments above -5℃, extending the annual construction cycle

II. Construction Quality Advantages

1. Eliminates water migration risk from the source

• 100% full adhesion to the substrate, forming a "skin-like" waterproof structure, completely blocking the water channeling passage under the waterproof layer, solving the water migration problem caused by traditional membrane loose laying and point bonding
• The coating automatically fills micro-cracks in the substrate, even if the substrate cracks 0.5~2mm, it will not affect the waterproof integrity
• The membrane overlap joints can be filled with non-curing coating, with bonding strength more than twice that of traditional hot-melt lap joints, no leakage risk at lap joints

2. High construction fault tolerance

• Insufficient local construction thickness can be supplemented at any time, no need for rework
• Coating damage during construction can be automatically repaired without affecting the overall waterproof effect
• Operation can be performed without professionally certified workers, manual scraping is simple and easy to learn, reducing the technical requirements for construction personnel

III. Construction Cost Advantages

1. Reduced direct costs

• No need to apply cold primer, eliminating the cost of base treatment agent
• Can be directly applied on the old waterproof layer, no need to remove the original waterproof base, reducing demolition costs by more than 80%
• Material loss rate ≤5%, much lower than the 10%~15% loss rate of traditional membranes

2. Long-term cost advantages

• Stable construction quality, post-maintenance rate is reduced by more than 70% compared with traditional waterproof systems
• Leakage maintenance does not require large-scale demolition, only grouting for leakage points is needed for repair, reducing maintenance costs by 60%
• Service life can reach more than 30 years, and the full life cycle cost is only 1/2 of that of traditional waterproof systems

IV. Construction Safety Advantages

• Solvent-free, no volatile toxic gases, no gas mask required during construction, meeting green construction requirements
• Non-flammable material, no fire risk during heating construction, can be safely constructed in confined spaces (such as basements, tunnels)
• No open fire operation during construction, avoiding fire hazards of traditional SBS membrane hot-melt construction
