IZOLEP-WP-11 — spray-applied epoxy waterproofing for bridge superstructure slabs

Mastics and liquid membranesOther anticorrosion materials

The main coat of the IZOLEP-WP-01 + IZOLEP-WP-11 + IZOLEP-WP-33 bridge waterproofing system: an epoxy compound that forms a seamless, elastic, waterproof membrane following the contours of the surface. It is used on railway and road bridges and overpasses — in ballast troughs, on carriageway and footway slabs, abutments and retaining walls. It is applied over IZOLEP-WP-01 primer by airless spray without thinning or by pouring; it withstands up to 230 °C for a short time when the protective asphalt concrete layer is laid, and the protective and decorative finish coat is IZOLEP-WP-33 enamel.
