Concrete installation with membrane technology

Save time with innovations

The manual trades need new methods and practical products in order to cope with the enormous stresses in the construction industry. Often only time-consuming installation techniques and unwieldy products are available, especially for electrical installation. We at Primo GmbH want to change that.

As trained electrical installers, we develop new intallation methods and products ourselves that minimise the effort or eliminate unnecessary work steps completely. We have received the BSFZ seal for this innovative competence.

Our motto: from professionals for professionals!

This allows the modern electrician to concentrate entirely on his work, saving valuable time and costs. As experts in our field, we also offer customers intensive support through our customer service or on-site training.


so that our customers receive all the information they need to be successful from the specialists.


because we want the best quality and more than a simple standard for our customers.


on site and equip our customers for their construction sites and projects.
