Our recent project in Orewa was installing porcelain tiles on floating deck. The challenge was that gap clearance from indoor to outdoor was very small, only 4-5 cm! So, decision was to install outdoor tiles 2cm thick using very small Karoapp deck jacks. We have supplied pedestals and ordered tiles from SSL Distributors.
At the end we have got very nice modern looking deck! And our clients were happy with result.
Deck jacks were only 18mm to 40mm.
