Polyurea

[/fusion_text][fusion_accordion hide_on_mobile=»small-visibility,medium-visibility,large-visibility» boxed_mode=»yes» border_size=»1″ title_tag=»h4″ title_line_height=»var(–awb-typography1-line-height)» title_letter_spacing=»var(–awb-typography1-letter-spacing)» title_color=»var(–awb-color8)» content_color=»var(–awb-color8)»][fusion_toggle title=»What is polyurea and what is it used for?» open=»no» title_color=»var(–awb-color8)» content_color=»var(–awb-color8)»]

Hot spray-applied polyurea is a high-performance waterproofing and protective coating. It is applied by trained and certified specialists using high-pressure equipment, creating a seamless, fully bonded, and highly elastic membrane that provides outstanding waterproofing and long-term protection.

[/fusion_toggle][fusion_toggle title=»What are the advantages of polyurea waterproofing?» open=»no» title_color=»var(–awb-color8)» content_color=»var(–awb-color8)»]

Polyurea offers extremely fast curing times, complete waterproofing performance, high elasticity, and excellent crack-bridging capabilities. It also provides outstanding mechanical and chemical resistance, making it a highly durable solution for demanding environments.

[/fusion_toggle][fusion_toggle title=»On which surfaces can polyurea be applied?» open=»no» title_color=»var(–awb-color8)» content_color=»var(–awb-color8)»]

Polyurea can be applied to a wide variety of properly prepared substrates, including concrete, metal, wood, EPS, GRP, polyurethane, and ceramic surfaces.

Its versatility makes it suitable for applications in construction, infrastructure, industrial facilities, sports and leisure projects, as well as demanding sectors such as mining and defense.

[/fusion_toggle][fusion_toggle title=»Is polyurea suitable for large-scale projects?» open=»no» title_color=»var(–awb-color8)» content_color=»var(–awb-color8)»]

Yes. Polyurea is particularly well suited for large-scale projects thanks to its high application rates and rapid installation process.

One of its main advantages is the extremely fast return to service of waterproofed areas, allowing other trades to continue their work with minimal disruption. This helps optimize project schedules, improve efficiency on site, and reduce overall construction time.
