Licensing of the technologies

In Germany, the hydros®PLUS and hydros®STAR (trenchless replacement and laying of new mains) as well as the starline® technology (fabric hose relining of mains) are carried out nationwide by Group of Karl Weiss. 

For these works, we use highly qualified personnel and state-of-the-art technical equipment.

We are happy to provide an offer for our construction services.

The licensing agreements have the following basic structure:

  • The licensee is given the know-how and the right to carry out the technology by obtaining a license. The licenses are usually limited to a certain area.
  • When obtaining the license, the licensee is also provided with the equipment, like pressure drums, transition pieces, adapters, etc., necessary for the technical implementation.

  • The licensing agreement will also include an extensive and thorough training program for the staff who is carrying out the works, so that the technology is applied in accordance with quality standards and in an economical manner for the licensee.
  • The licensor agrees to provide the licensee with a sufficient amount of all consumable materials necessary for the implementation of the technology, like hose material, adhesive, etc. The licensee is also provided with necessary spare parts for the licensed equipment by the licensor. 
  • Licensor and licensee mutually agree to work together in a cooperative and confidential manner. The licensor will always support the licensee to the best of his ability and will be available for consultation.
The ever improved performance of the hydros® and the starline® technologies indicates that these two technologies have become established on the market and are recognized nationally as well as internationally as trenchless technologies with a high quality standard.
