Hobas pipe jacking under Dutch highway

In the municipality of Roosendaal in southern Netherlands, 150 m Hobas GRP pipes OD 1280 were installed via microtunneling in a depth of 4.5 m underneath the A58 highway. The pipes are part of a sewer system extension for Norbartlaan road – they will drain stormwater in case of heavy rains and thereby reliably prevent the road from being flooded.
