SAFE.RELIABLE.SUSTAINABLE.
More than 25 years ago, the idea for an innovative product was born: a super-hose for the trenchless rehabilitation of pressure pipes should come to life. This was intended to solve the problem of the time-consuming and cost-intensive rehabilitation of existing pipes using the open trench method.

Five years of intensive development work full of passion and determination passed from the idea to the market maturity of Primus Line® technology in 2001. This spirit of development continues to this day, as the company sees itself first and foremost as a safe, reliable and sustainable solution provider.

SAFE.
The safety of our product is based on premium materials, sophisticated design and continuous quality control. We only use top-quality raw materials and rely on optoelectronic and optical measuring devices to monitor the entire production process. Every production batch is subject to a pressure test before delivery. The reinforcement of the liner consists of seamlessly woven Kevlar®. This synthetic fibre is up to ten times stronger than steel. Tests based on international standards confirm our promise of safety.
