Description FASTFILL is a single component, polymer modified, fibre reinforced Portland cement based repair mortar. It is rapid curing with enhanced polymeric properties and reliable strength development which is not significantly affected by low temperature use. Can be used as supplied up to 100mm deep, or bulked out with sharp sand or aggregate to a flowing consistency for floor or deck repairs up to a maximum depth of 300mm. Uses Durable repair of concrete subject to heavy wear such as roads, runways, bridges, decks, floors and footpaths. Suitable for repair methods 3.1, 3.2, 4.4, 7.1, 7.2 as defined by BS EN 1504-3.
