Hot Melt Structural Waterproofing
One of the first Hot Melt structural waterproofing membranes was developed in the early 1960’s by Uniroyal Ltd. In 1977 American Hydrotech acquired the distribution rights to Hot Melt membrane ‘Monolithic Membrane 6125®’ for the United States. Over the next three decades more than 185 million m2 was installed in over 86 countries. In July 2021, Sika acquired American Hydrotech, bringing this long-established waterproofing technology into the Sika portfolio.
The introduction of SikaShield® Hot Melt 50/70 to the Sika Roofing UK product range enables Sika to offer all four common generic roofing technologies; Hot Melt, Liquid Applied, Reinforced Bitumen and Single Ply.
Sitting directly on the structural deck, beneath the insulation board in a Warm Inverted Roof build-up, the insulation and Water Flow Reducing Layer (WFRL) are held in place by a loose-laid surface finish such as a Sika NatureRoof Green Roof, Sika NatureRoof PV BioSolar Roof, Gravel Ballast or Cast Stone or Mineral Paving Slabs. Sika RetentionRoof Geocells can be inserted between the WFRL and surface finish to create a Blue Roof.
These roof assemblies provide a BBA certified roofing system that has a durability statement for the life of the building and comes with a comprehensive system guarantee from Sika.
