Idea of materials to produce of foundation chocks have been worked out to the needs of shipbuilding and the first wide practical application of such chocks were noted just there. At present they have been utilized in wide range in foundation of engines and gears of main propulsion, in assembly of stern tube, sleeves of rudders and other various auxiliaries in engine rooms, deck facilities, bearings of pillar cranes, and so on. Thanks to many their qualities, they have been also used more often not only in shipbuilding industry, but in foundation of many various and heavy engines and machinery to use on land as well.

During 40 years (since 1974 until the end 2013) of practical application of Polish chocks cast in EPY, there have been seated 11221 various objects including 9896 marine engines and machinery and 1325 land engines and machinery as well. Such operations were performed by the Szczecin Polytechnic University and such companies like KITI and Marine Service Jaroszewicz.
