Special waterproofing solution Wetraffic 420 between two asphalt layers under the tartan surface.
On the running oval in Vinohrady, it was necessary to provide waterproofing between two asphalt layers under the final tartan surface. Due to Water permeability of the structure It was crucial to prevent water from entering the dressing rooms under the oval.
It was therefore applied high temperature resistant waterproofing Wetraffic Wecryl 420 (1.5 kg/m²)which can withstand both the temperatures of fresh asphalt and Extreme mechanical stress during laying.
Implementation took place on the surface 870 m² in 16 hours in one work cycle.
The result is reliable protection of the structure against water while maintaining the functionality of the sports surface.
Detail of the underlying asphalt layer with applied waterproofing screed Wetraffic Wecryl 420 in the amount of 1.5 kg/m². The waterproofing layer is designed for resistance to high temperatures during the laying of bituminous mixtures and at the same time provides protection of the structure against water penetration into the lower layers.
Laying of hot asphalt mixture on the waterproofing layer Wetraffic 420 applied to the underlying asphalt. Waterproofing exhibits high temperature resistance of a freshly laid asphalt mixture, while withstanding mechanical loads of construction equipment.
The final state of the waterproofing layer Wetraffic Wecryl 420 applied to the underlying asphalt in the projected quantity. The layer is continuous, without breakage, prepared for overlaying with a top bituminous mixture and providing long-term protection of the structure against water penetration.
