How to apply an adhered roof?

An adhered membrane could be considered for many applications, including refurbishment where the existing surface is sound and remains firmly attached to the substrate, or for concrete decks where the use of mechanical fasteners maybe problematic. Additionally, as the membrane is exposed, any alterations are easily executed, as access is easy.In adhered applications, Sika-Trocal SGK is bonded to the substrate using a polyurethane based adhesive to secure it against wind uplift forces, with peel stops fixed at all changes of plane and around perimeters to ensure full security of the membrane against wind forces.


Sika-Trocal Adhered Roof Systems

Sika-Trocal SGK 1.2 (thickness 1.2mm) and 1.5(thickness 1.5mm) is a multi-layer, synthetic roof waterproofing sheet based on premium quality Polyvinyl chloride (PVC) with an inlay of glass non-woven and polyester fleece backing. 

An identical sheet to Type S with the addition of a layer of random glass fibres in the middle of its thickness which is designed to virtually eliminate shrinkage and provide the necessary dimensional stability.

 Also incorporates a polyester fleece imbedded to the underside of the membrane to provide a key for adhered applications. Often used for exposed membrane applications where the use of mechanical fasteners is inconvenient or not possible, renovation of existing roofs, cold stores, concrete decks or aesthetic reasons.
