Overview of Inverted Waterproofing Roof Membrane Systems
MRC’s ‘Inverted’ or ‘Protected Membrane’ roof systems with ballast, paving or green roofs use our PVC or TPO monolithic synthetic single-ply waterproofing membranes and are perfectly suited to use on any new build or refurbishment of flat roofs.
Hydrophobic Insulation such as graphite enhanced Neopor® or Expanded Polystyrene is installed above the membrane to suit the R-Value required. The insulation provides a drainage layer and protects the membrane below from extreme weather i.e. excessive heat or high UV exposure thereby extending the life of the synthetic single-ply waterproofing membrane.
On the top of the insulation there is a range of different finishes include ballast, paving or a green roof installed to suit the requirements of the client.
Inverted roofs have been used throughout the world for over 40 years, ensuring the longevity of the waterproofing system like bitumen torch-on, liquid applied waterproofing or single-ply waterproofing membrane.
MRC Group’s installed system is backed with the unrivalled, single source, Guardian™ System Warranty covering materials, installation & maintenance for the term of the Inverted Roof.

[wptab name=’Guarantees & Warranties’]
Guarantees & Warranties of a Single Ply Roof Membrane System
MRC Group’s up to 20 year ‘Guardian’ System Warranty cuts through the myth & mystic of product guarantees and workmanship warranties issued by the construction industry.
Traditionally a product guarantee would be issued by the manufacturer and the workmanship warranty would be issued by the installer of the single ply roof membrane system. Two separate pieces of paper, with differing length of terms and when put alongside each other, never answered the question of who will pay for the materials and works if the waterproofing system fails.
‘Guardian’ System Warranty is an unrivalled new era of warranty that covers Materials, Workmanship & Maintenance. The length of term for each element matches and is issued as a single source, transferrable warranty for the life of the guarantee of the single ply membrane roof system.
MRC Group challenges the construction industry to ensure that the workmanship warranty issued by contractors matches the length of term of the supplied roof system, thereby ensuring high quality installations with designed and tested single-ply roof membrane waterproofing systems.
