When it was founded in 1983, Siebert + Knipschild GmbH was Germany’s first testing institute for thequality assurance of pipe liners. Since then, other plastic construction products for the drainage sector have also been tested. The company is – then as now – one of the leading testing laboratories in Germany in terms of technologies and procedures for rehabilitation and repair of underground pipe networks. In addition, we act as an inspection body in the manufacture and installation of plastic componentsand prepare material analyses of industrial and consumer goods. Giving clients and contractors independent assurance for their project – that is our mission.
