Fillers and granules suitable for mastic asphalts, roofing systems, carpet backing, waterproofing and surfacing macadams.

Longcliffe supplies limestone fillers for use in bituminous roofing membranes and roofing felts, helping to reduce construction costs and to provide a waterproof covering for the building. Our limestone fillers can also be used for mastic asphalt, polymer-modified mastic asphalt systems and carpet backing.

Mastic asphalt has a long and successful history as a waterproofing medium for flat roofs, water tanks, basements and foundations and we are confident that our limestone provides these beneficial qualities for the construction industry.

Bituminous products are also used to produce surfacing materials for floors, pavements, car parks and bridge decks, adding strength to the final product. 

Longcliffe's Longcal product of fine limestone grits is suitable for the addition to the top coat for roofing felts manufactures.
