Viking Decoupling System
Description

The Viking Decoupling System is to be used where tiles are required as an overlay of a waterproofed deck and when installation of the Buzon pedestal protection system is not an option.

It is designed to allow independent adhesion of tiles over Viking Enviroclad when used as a deck waterproofing layer. As the name suggests the Viking Decoupling system provides a slip or decoupling layer between the waterproofing layer and the tiles. 

The Decoupling system is laid over the waterproofed substrate with a base adhesive which is designed to ‘let-go’ after the tiles have been adhered to the top face of the decoupling sheet. This ensures that movement within the building substrate and movement in the tiles can be kept independent and most importantly protect the waterproofing layer. If later removal of the tiles is required this will not adversely affect the waterproofing layer.

Viking Decoupling System is an accessory to complement Viking Roofspec’s Enviroclad 1.52mm waterproofing membrane. 

Key Features
  • Allows independent movement of tiles and the substrate
  • Reduces latitudinal stress caused by heating/cooling
  • Protects the waterproofing layer
  • Tiles may be removed at a later date without adversely affecting the waterproofing layer
  • Suitable for laying tiles where pedestals may not be possible or desirable
Scope of Use
  • Designed to allow independent adhesion of tiles over Viking Enviroclad when used as a deck waterproofing layer
  • To be used where when installation of the Buzon pedestal protection system is not an option
Limitations on Use

Viking Decoupling System is an accessory to complement Viking Roofspec’s Enviroclad 1.52mm waterproofing membrane.

Installation of substrates must be carried out by Tradespersons with an understanding of roof and deck construction in accordance with instructions given within the Viking Roofspec technical literature and the Dec-K-ing Substrate checklist with the aim of minimising and where possible controlling substrate movement.

Other Performance Attributes

Viking Decoupling System is made of yellow polypropylene with a mesh fabric and a backing fleece which is also made of polypropylene. Due to this material composition, the mat is resistant to many corrosive chemicals (salts, acids and alkali) at low concentrations.
