Small space requirements, low costs, less disturbance to residents and the environment: trenchless construction is gaining ground. This also includes the renewal of subterranean infrastructure, the core expertise of Sekisui SPR.

At No-Dig Berlin, the international group will be presenting its broad technology and service portfolio on a space of over 70 square metres, together with its subsidiaries, Sekisui NordiTube, Sekisui Rib Loc und KMG Pipe Technologies.

The main focus of the event presentation will be the SPR and Nordipipe technologies. Fair visitors will be able to acquaint themselves with SPR technology in a live demonstration: a spiral-wound pipe lining method, specially developed for rehabilitating large diameters.

The system consists of a spiral-wound pipe liner made of steel-reinforced PVC profiled strip and high strength grout filled in the annular space between the spiral-wound pipe liner and old sewer.

Nordipipe technology was developed for the trenchless rehabilitation of pressure pipes. The fibreglass-reinforced pipe liner for the rehabilitation of drinking water pipelines is statically self-supporting and can resist high internal pressures and general exterior loads.
