We are fully specialized in telecommunication network construction. As construction methods evolved, the industry faced a shortage of expertise in microduct technology. To meet this need, the owners of our companies — with backgrounds in various fields — established a company dedicated solely to this technology. Today, together with our parent company Konepalvelu Kuivas Oy, we are the nationwide leader in microduct-based network construction and a recognized pioneer in the field.

We are committed to continuous improvement, ensuring that our work consistently meets the highest standards of quality and efficiency. This allows us to serve our customers’ needs across every aspect of a project.
