A traditional material, mastic asphalt has a proven track record and has been extensively used where the client seeks a robust, cost effective solution. Mastic asphalt is impervious to water and is vermin and rot resistant. Suitable for most flat roofing substrates including in-situ concrete, pre-cast concrete, metal, timber and plywood decks; mastic asphalt can be used on flat, curved and sloped roof areas, in warm, cold and buried roof applications. Applied molten, it can be worked around most roof protrusions ensuring a continuous finish. Mastic asphalt also makes an ideal substrate where a tiled finish is required.
IKO manufactures a number of different mastic asphalt grades to ensure the client needs can always be met. All grades of mastic asphalt can be supplied as nominal 20kg blocks ready to be melted on site. For larger projects, it is supplied direct to site in purpose built hot charge transporters as a ready to use material. Contact us for further details.
