LaserShell™ enables real-time and remote construction of any underground space through use of a specialist geospatial survey system, TunnelBeamer™, in conjunction with a high quality steel fibre reinforced sprayed concrete.

Offering an inclined advance sequence and systematic profile control, LaserShell™ not only greatly enhances safety, but also enables tunnels to be constructed more quickly and to higher quality than traditional methods.

LaserShell™ was first used as part of substantial tunnelling works for an airside road tunnel beneath Heathrow Terminal 5, resulting in cost savings to our customer of more than £10 million.
