Once applied, it provides a high performance continuous elastomeric membrane for waterproofing of roofs, terraces, bridge decks, underground structures, etc.

APPLICATION FIELDS

Waterproofing and protection of all types of roofs, green roofs, terraces, balconies, etc. Waterproofing of bridge decks, parking decks, etc.
Protection of polyurethane foam insulation. Waterproofing of channels, reservoirs, wastewater treatment plants and other water retaining structures, etc.
Protective coating on drainage boxes, retaining tanks or areas exposed to spillages and spattering of chemical compounds


ADVANTAGES

Forms a seamless continuous membrane.
Very good chemical resistance to water, seawater, wastewater, fuels, grease and oils, de-icing salts, diluted alkali and acid solutions, etc.
Very good elasticity, tear strength and abrasion resistance. High yields by spraying means.
