PIASKARZ Przedsiębiorstwo Produkcyjno-Handlowe SA 02-954 Warsaw, ul. Królowej Marysieńki 28 KRS 0000140613 NIP 521-012-14-97 Regon 001299159 We have been on the aggregates market for 30 years We have been operating on the construction market since 1988, initially as a limited liability company, and since 1990 as a joint-stock company. We mainly mine, manufacture and sell aggregates for the construction and road construction industries. Our company consists of five production plants located in the Masovian Voivodeship. There are four sand pits in Warsaw and a mining plant in Osówka near Żuromin. At sand pits in Warsaw, we extract river sand from the Vistula, on the left side of the river in Bielany and Kępa Zawadowska and on the right side in Tarchomin and Miedzeszyn. We use a modern, high-performance dredger to extract sand. The raw material sucked from the bottom of the river by a dredger is sent to the shore by means of dredgers, where its landfill is located. The use of such technology does not adversely affect the environment. At the same time, the operation of the dredger does not exceed the permissible noise standards, and the sand sent by dredgers does not cause dust. In the mining plant in Osówka, we extract mine sand and gravel from dry seams with the use of highly efficient excavators and loaders. In 2010-2011, we launched an additional field located in Ruda and Wiadrowo (near Osówka) All our products have the required quality tests. We ensure the high quality of our goods and services through the use of modern equipment in the extraction and production of aggregate, mainly during sorting, screening and proper storage, as well as through professional service. Such activities guaranteed us constant commercial cooperation with a large group of partners from the construction industry. We are a reliable and solid company.
