Mega Chocks for Tunnelling
Large-scale tunnel construction requires accuracy and repeatability.
If you operate in the UK tunnelling industry the innovative Mega Chock could save you time and deliver improved cost efficiency.
Designed to provide unrivalled support during construction, the Mega Chock is used during the storage of pre-cast concrete tunnel segments and makes transportation safer and easier.
Made from reinforced glass fibre and similar to Kelly Blocks in appearance, Mega Chocks are ideal for the storage and transportation of pre-cast concrete segments prior to their use, either in single or twin-bored tunnels using TBMs.
Whether you’re tunnelling to house cables, utilities, water, trains or vehicles; you can rely on the Mega Chock to simplify the process.
