• Smart Identification: You will easily distinguish between high and low voltage networks thanks to the indelible longitudinal color lines.
• Patented Protection: You will protect your cables from static electricity and internal scratches during routing.
• Easy Installation: You will pass the steel wire or cables instantly with the pre-installed 65 kg strength guide.
• Top Waterproofing: You will ensure absolute insulation, reaching an IP68 rating by using the special KOUVIDIS adhesive.

You will be impressed by the engineering behind the GEOSUB pipe from KOUVIDIS. Designed as the ideal "little sibling" of the popular GEONFLEX for projects with lower mechanical requirements (strength 450 Nt), it features a double-wall structure made from environmentally friendly halogen-free thermoplastic HDPE. Its advanced 2nd generation design includes a third outer layer with color coding, which helps the designer and installer quickly identify the application field of the underground network.

You will appreciate the integration of two leading patents: antistatic technology that repels static electricity and scratch-resistant technology that minimizes wear on the smooth inner wall during cable pulling. The conduit is fully resistant to solar radiation (UV), offers excellent insulation, and is certified by the reputable German laboratory VDE, ensuring top professional reliability.
