Spray polyurea roof waterproof application

Project Situation

An 8,500㎡ industrial plant originally used SBS waterproof coil,5 years later due to ultraviolet aging, joint cracking caused serious leakage, the annual maintenance cost is high.

Customer Demand:

1: More than 20 years waterproof life

2: 7 days to complete, reduce production loss

3: Environmental protection and no pollution

Spray Polyurea Solutions：

Using spray polyurea PS500A (100% solid content) to reshape the waterproof system with technology:

✅ Material breakthrough:

1: High-pressure spraying to form a 2mm seamless film layer to eradicate hidden dangers in joints

2: Tensile strength ≥20MPa, fracture elongation ≥450% (3 times more than coil)

3: Passed GB/T 23446-2009 standard, theoretical life of 30 years +

✅ Construction Technology:

1: 3 days to complete the base treatment + spraying (daily effect 1,200㎡)

2: Intelligent devices accurately control the film thickness (error ±0.1mm)

3: 3mm reinforced spraying of special-shaped parts, zero pinholes detected by EDM

✅ Environmental advantage: zero VOC emission, the plant runs normally during construction

Industry Value:

Technology long-term protection: With seamless integration, UV corrosion resistance, redefine the waterproof standard;

Complex scene adaptation: Overcome problems such as irregular structure and extreme temperature difference (-30℃~50℃);

Win-win for the green economy: 42% reduction in life-cycle costs and 60% reduction in carbon emissions.

Application Scenario:

✔️ Industrial/commercial buildings ✔️ airport, cold chain warehouse ✔️ pharmaceutical/food high-standard factory
