HOBAS Tunnel Drainage Systems

HOBAS CC-GRP Pipes have a high content of highly flame-retardant components (e.g. glass fibers and mineral reinforcing materials such as aluminium hydroxide), which makes them perfect for tunnel applications. The design and realization of flame-retardant pipelines is subject to national regulations. Please contact the HOBAS Engineer responsible for your area for more details.

A special liner resin creates a smooth and glossy pipe surface that improves the pipes’ hydraulic properties considerably and prevents incrustations with mineral deposits.
