System 20 MR Charcoal
Clark & Son Structural Waterproofing Ltd
Ashton Pioneer Homes
There were various challenges to this project which included the following;
- to carry out re-roofing with a 15 year insurance backed warranty whilst the buildings were still tenanted with least disturbance and noise to the occupants,
- to work round the existing radio transmitter dishes and cables situated on the roof,
- to remove all the superfluous details such as redundant vent chimneys and pipe work. With the buildings still being tenanted the client preferred option was for an overlay system that would make use of the existing insulation and lead to the least disturbance.
System 20 MR Charcoal; the solution put forward was to use the System 20MR, a specialist bituminous membrane that is designed specifically as a single layer product to go over existing mineral. The first layer of bitumen on the System 20MR is an easy flow PAO material that is designed to knit into the existing mineral and grant excellent adhesion. This meant that the roofing works could be carried out to meet all the clients’ requirements whilst remaining cost effective.
