An adhered membrane could be considered for many refurbishment applications where the existing surface is sound and remains firmly attached to the substrate, or for concrete decks where the use of mechanical fasteners maybe slow and tedious. Additionally, as the membrane is exposed, any alterations are easily executed, as access is easy. Similarly, any damage is easy to spot and repair.

 

This type of roof is not suitable or intended to be heavily trafficked or subjected to public or leisure usage. Nor is it a suitable surface for an ‘overroof’ fire escape route. If the roof under consideration is overlooked by windows in higher buildings, access paths, roads, patio areas etc, the risk of items such as discarded cigarette ends, bottles, rubbish etc, which can all cause damage, being thrown onto the roof surface needs to be taken into account. With overlooked roof surfaces the aesthetics should always be considered. In all these cases the alternative choice is likely to be a ballasted roof.

 

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.

 

Suitable for both new build and refurbishment applications, in both warm roof and cold roof construction, Sika-Trocal adhered systems are generally used for concrete deck applications where the use of mechanical fasteners may be slow, tedious and costly. Sika-Trocal adhered systems can also used as the primary waterproofing on Cold Store composite panels.

 

In refurbishment applications the condition of the existing surface must be sound and remain firmly attached.

Product Details

Sika-Trocal® SGK

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.
