Trocal Type SGMa slabbed after completion for a durable, neat finish.
It wasn't our biggest project but it is our most prestigious project of 2017, given the venue; it's not every day we get to carry out work on a Cathedral even if was only Shrewsbury and not St Pauls in London. It was a live project with a Cafe underneath the work being carried out. 120sm of Trocal Type SGma, a ballasted membrane, completed in ten days, on time and to agreed budget. No hanging around!
The original roof cover was stripped of its covering and cleaned of all debris in preparation for the recover. Not a pretty site! However, this was necessary to a quality, durable finish.
The insulation is then laid out. As this was a tapered scheme, we have to work to the manufacturer's plan, laying out the insulation boards in a specific order to maintain the taper and avoid an uneven finish.
Trocal metal details were then fixed to the perimeter. Trocal metal is an integral part of all Sika Trocal projects and is custom made as required by each individual project. Sika Trocal metal allows us to adhere the membrane to the perimeter details to maintain the integrity of the waterproofing membrane.
