Over the following years ??IIG?? became a medium-sized enterprise, continuously growing thanks to its flexibility and high standards of quality, thereby creating the foundation for the purchase of a 12,000 m2 site at the start of the 80s. In 2008 the strategic decision was taken to expand the IIG Group?fs presence in the market with the key service of providing industrial maintenance to the process industry. Pipework Construction was added to the Technical Insulation and Industrial Cleaning divisions of the Group in 2008 with the creation of IIG RAR-Rohrleitungsbau GmbH.
