Wasa has been the embodiment of high-quality production boards for the concrete block industry since 1960. It was founded by Walter Salje – the Wa-Sa company name is derived from his initials –, who began in 1960 to simply trade in production underlays for concrete block-making machines. Heinz Bechtold joined Salje’s trading company in 1978 as a qualified forwarding agent and took over the company from the childless Salje two years later. He changed its name to Wasa Unterlagsplatten GmbH and commenced manufacturing products in-house. Today, sixty years after its foundation, Wasa has developed into an industry leader and has widened the breadth of its product range extensively.
