Permascreed mastic asphalt screed is manufactured in the UK from selected bitumen’s, limestone filler and specially graded aggregates. It is designed to provide drainage falls as well as a stable base for the specified roof waterproofing system.
Permascreed can be applied at a wide range of thicknesses (minimum 10mm) and falls, usually on in-situ and pre-cast concrete bases. It is suitable for insulated warm roofs, inverted roofs, green roofs and balcony or terrace applications.
