Inadequate roofing affects a structure's functionality, its maintenance and whole-life costings, with far-reaching implications for building insurance. A durable roof waterproofing system that is resistant to changes in temperature and environmental factors, such as pollution and acid rain, is therefore a vital part of the building envelope.

Pitchmastic PmB provides tailor-made solutions for flat and pitched roofs with its versatile Blueshield PmB and Roofshield PmB waterproofing systems, which use advanced polyurethane technology to create impervious, monolithic membranes suitable for all major roof types and designs.  

BlueShield PmB is multi-layered, comprising primers, membranes and protective topcoats. The system is cold applied to avoid the odour and fire risk of hot works. Custom-designed spray equipment ensures consistently high quality membrane production and quick, uniform application. Fast curing within a few minutes speeds up installation; up to 1,000m2 can be sprayed in a single shift. Our products are suitable to be applied across a variety of substrates and in a wide range of climates. Roofshield PmB is a BBA certified cold liquid applied fully reinforced roofing membrane designed for both new build and refurbishment applications. Designed to overcoat existing mastic asphalt, felt, single ply and various other substrates, guarantees up of to 25 years are available.
