Because of the damp environment in Mill Run, Pa., and Fallingwater's design, which allows water to flow over the building like a waterfall, terraces feature waterproofing materials (above). Fallingwater's low-slope roof systems feature Siplast Paradiene 20 TG S, Paradiene 20 TS, Paradiene 20 EG and Parafor 50 LT.

Flagstone pieces were photographed, mapped and numbered before they were removed for terrace restoration work. This ensured all flagstone pieces were returned to their original positions.
