A pad utilizable in padding, levelling or aligning girders, rails or any other constructional or structural elements. The pad comprises at least one thermoplastic plate member and an electric heater for heating the thermoplastic plate member to soften or melt to cause the overall thickness of the padding material to be reduced to a value sufficient to bring an article or machine to a predetermined level. The plate member is made of a thermoplastic polyester material of a composition which substantially comprises a crystalline polyester segment having a high melting point or a softening point and a non-crystalline polymer segment having a low melting point.
