Roof Insulation with Polyurea
What is Polyurea?
Polyurea is one of the most advanced waterproofing and protection systems, widely used in industrial, commercial, and high-performance projects that require superior resistance to water, impact, abrasion, and chemicals.
Polyurea is produced through a fast chemical reaction between the Isocyanate Component and Amine Resin, which are mixed at a 1:1 ratio inside the high-pressure EvoPur H-19S NEW spray machine. This creates a flexible, seamless, and uniform membrane within seconds, without joints or seams.
Polyurea is characterized by an elongation rate of up to 600%, along with very high resistance to abrasion, wear, and friction, making it one of the best solutions for waterproofing and protecting concrete and metal surfaces while extending their service life.
Why is Polyurea used in high-performance applications?
Polyurea is known for its rapid reaction and fast curing, forming a flexible and continuous Seamless Membrane that covers all parts of the surface, including corners, edges, and detailed areas, without joints or seams that may allow water leakage.
It also provides high resistance to impact, friction, abrasion, and wear, in addition to excellent resistance to a wide range of chemicals, acids, and alkalis. This makes it an ideal choice for factories, warehouses, water stations, and industrial facilities operating under harsh conditions.
The system can be applied at different thicknesses according to the nature of the project, with an application speed of up to 500 m² per day using one spray machine, helping reduce project duration and allowing the site to return to operation quickly.
How does the Polyurea system work?
After being sprayed onto the surface, Polyurea forms a flexible and uniform layer that strongly adheres to concrete or metal, creating a continuous membrane that prevents water leakage and protects the surface from abrasion, weather conditions, chemicals, and mechanical impact.
It is also known for its fast curing time, with an initial curing time of 5–15 seconds, while the thickness of the insulation layer can be controlled according to project requirements and performance needs, providing a long-term protection system for surfaces under different operating conditions.

Application Areas
The TRI-POLY-U HM Polyurea system is used for waterproofing and protecting concrete and metal surfaces, factories, warehouses, water tanks, swimming pools, metal structures, and many industrial and commercial projects that require a high-performance waterproofing and protection system.
Execution Steps
1. Surface Preparation
The surface is thoroughly cleaned to remove dust, oils, loose materials, and any unstable layers. Loose parts are fixed, cracks are treated, and rust or damaged areas are removed to ensure the surface is ready and to achieve maximum adhesion for the insulation system.
2. Primer Layer Application
The transparent TRI-COAT PU, reinforced with a Fleece Reinforcement layer, is applied as a primer layer. Joints, corners, and critical areas are treated when needed to enhance adhesion and improve the overall performance of the Polyurea system.
3. Polyurea Spraying
The TRI-POLY-U HM system is sprayed using the high-pressure EvoPur H-19S NEW machine, which mixes the Isocyanate component Part A with the Amine Resin component Part B at a 1:1 ratio.
The material is then sprayed at the required thickness to form a flexible, seamless, and uniform membrane with superior resistance to water, impact, and chemicals.
4. Final Protective Coating
After spraying the TRI-POLY-U HM system, a final protective coating is applied in the required color. This helps maintain color stability, provides a uniform aesthetic finish, and adds extra protection against weather conditions and UV rays, ensuring the efficiency and long service life of the insulation system.

Frequently Asked Questions
Is Polyurea suitable for all types of surfaces?
Yes, Polyurea can be applied to concrete, metal, and other surfaces after proper preparation and the use of the suitable primer layer.
What is the difference between Polyurea and Polyurethane?
Polyurethane foam is mainly used for thermal insulation, while Polyurea is used as a high-performance waterproofing and protective membrane. Polyurea provides higher resistance to impact, friction, abrasion, and chemicals.
How long does Polyurea application take?
Polyurea is known for its fast application and curing time. Large areas can be completed in a short period, with an initial curing time ranging from 5 to 15 seconds, depending on site conditions.
Can the final protective coating color be selected?
Yes, the final protective coating can be applied in the required color according to project requirements, while maintaining the efficiency of the insulation system and providing a uniform aesthetic appearance.
What is the expected service life of the Polyurea system?
When the Polyurea system is applied using high-quality materials and according to the correct technical specifications, its service life can reach 25 years or more, depending on operating conditions, usage type, and regular maintenance.
