Wausau Tile’s Roof Deck Pedestal System features the Terra System One pedestal system which helps you navigate the challenges of a pitched surface, roof plaza, parking garage or roof terrace with ease. Our system provides a level surface for installation of concrete pavers over a pitched surface from 1/8” to 21 1/2”. It also ensures precise paver alignment with even spacing to allow drainage and air circulation critical to the health of a deck installed over any waterproof membrane. It allows for easier access to the subsurface for scheduled maintenance or repairs without damage to the paved surface.
