    Trump Tower Baku - Petra Alba Travertine

    November 21st, 2014 in Case Studies, Factory Visits, General, New Stone, Uncategorized

    This week we visited Verona to inspect the first few containers of our PETRA ALBA Travertine being loaded and shipped to Baku to be used as column cladding and flooring in the new Trump Tower. Approximately 3000sqm of 2cm (floor) and 3cm (wall) have to be prepared and shipped in just 6 weeks.

    Our PETRA ALBA Travertine had been selected and specified by as a perfect solution with which to clad the columns. The original Silver too stronger veins and Classic Travertine too dark.

    To make sure the slabs are filled and polished to the highest standard and loaded on time our Petra Alba blocks are cut into slabs close to the quarry in Rapolano and then taken by truck to Verona where the most up to date professional companies can process 1000’s of square metres daily.

    Our Petra Alba Travertine is one variety from an old quarry in Rapolano reopened recently and being offered again exclusively through GDS. Other colours from this quarry will follow but this particular one is proving very popular and has turbulent structure of Alabastrino, muted metallic tones seen in the Silver (the famous Silver is the neighbouring quarry) and the light aspect typical of Navona.

    We were inspecting the polished production during this trip. We specified colour resin filled in both polished and honed but as the slabs are initially filled honed, then filled again and finally polished we had a chance to see how the slabs would look in both finishes.

    The travertine is pretty close grained and generally the holes are small. Occasionally there were longer voids along the grain (as you can see in the image of the sawn slabs at the start of the process) but never more than 5-6mm at the widest point. These as I say, were infrequent. The resin filler was a (roughly) measured mix of a large dollop of beige and a small dollop of white. It was applied to the whole face. Masking tape was applied the back of the slab where holes were larger and went all the way through (as happens when blocks vein cut) would stop any resin wanting to go straight through and out of the back of the slab.

    After the resin was applied, the slab was baked in the oven fitted to the production line. The resin hardens then is honed with various heads in the polishing section of the tile. The slabs are then sent back down the line again, filled again to sort out any smaller holes that have been missed and then baked and back under the polishing heads for a second time to be taken to a full polish.

    Anyway, sorry to bore everyone to pieces but thought I would explain the process. We feel very privileged to supply such a high profile project and will no doubt report back again as things progress. Next week the Petra Alba quarry in Rapolano.
