Demolition contractors in Turkey usually expend a lot of effort on salvaging as much building material as possible from the buildings they demolish. The reason being that used building materials (UBM) are in considerable demand by lower-income urban communities for house repairs and construction, and a substantial amount of profit is made by selling such material. Although a number of demolition contractor’s yards (DCY), which are also the outlets for UBM, exist in all major urban centres of Turkey not much is known about their existence or merchandise by the public at large; the buyers being mostly squatters.
