Skills that open doors
Large-format porcelain and slab
Tiles and slabs the size of a door. Hard to handle and in demand.
Natural stone and marble
Expensive material, so builders want someone who will not waste it.
Waterproofing systems
Shower membranes and shower pans. A failed shower is a costly callback, so this skill is valued.
Terrazzo and mosaic
Lobbies, transit stations and restoration work.
