Waterproofing with hot-sprayed pure polyurea
Waterproofing and coating with hot-sprayed pure polyurea
Hot-sprayed pure polyurea is one of the most advanced solutions for waterproofing and coating of building and industrial structures.
This system creates monolithic, elastic, and highly durable membranes, protecting concrete, metal, and other surfaces from water, chemicals, abrasion, and mechanical wear. Thanks to its rapid polymerisation and strong adhesion, polyurea ensures long-lasting, high-performance interventions, providing complete protection even in complex environments or under high stress.
Typical challenges in the sector
Installing a pure polyurea system presents technical and operational complexities that require qualified professionals and specialised equipment:
Thorough substrate preparation: perfect adhesion depends on the cleanliness, roughness, and moisture content of the surface.
Environmental control: temperature, humidity, and ventilation can affect the chemical reaction of polyurea.
Extremely rapid polymerisation: polyurea cures within seconds, requiring highly trained personnel to ensure uniformity and continuity.
Specialised equipment: high-pressure spray machines with controlled heating, along with strict safety procedures, are essential.
Compatibility with various surfaces: concrete, metal, existing membranes, wood, or irregular surfaces require specific primers and targeted application techniques.
FES Global Group’s approach
FES S.p.A. uses hot-sprayed pure polyurea as a high-performance solution for waterproofing and coating, following a precise, tested methodology:
Preliminary substrate analysis: technical inspections, adhesion tests, and hygrometric evaluations to define the most effective application cycle.
Professional surface preparation: mechanical cleaning, shot blasting, milling, or priming with carefully selected materials.
High-pressure controlled application: certified equipment ensures a continuous, uniform, joint-free coating.
Monolithic waterproof membranes: polyurea creates an elastic layer without weak points, resistant to infiltration, thermal shocks, chemicals, and wear.
Total intervention flexibility: roofs, tanks, parking areas, walkways, drainage channels, industrial plants, flooring, and high-stress structures.
Extremely fast reactivation times: surfaces are operational within hours, minimising downtime and disruption.
