Tunnelwell® is a whole of lifecycle solution

Tunnelwell® meets AS 5100, Australian Bridge Code Design requirements. Generally wall thicknesses are scalable to meet varied load requirements making Tunnelwell® the only scalable wall thickness arch offering in the world. Tunnelwell® arches are roto moulded which allows scalability in production processes to meet non traffic to high traffic loads by varying wall thicknesses – this saves $$$$$.

Tunnelwell® arches by design negate the need for Geosynthetic cloths completely and the requirements for blue metal stone structural support! Tunnelwell® is made of polyethylene (LLDPE) not polypropylene. Polypropylene arches and box systems have a short elasticity life and external vibrations weaken the structures which cause them to fail over time. Not so with polyethylene products. Tunnelwell® is fully accessible for maintenance and inspection by personnel not cameras!
