At the Bank Station Capacity Upgrade project, we are using the Mapelastic TU system to waterproof the new sprayed concrete lined tunnels that are currently being constructed.

We understand this system and the Mapelastic material has not been used previously on tunnel projects in the UK.

We believe the Mapelastic system offers the following distinct advantages over the industry standard:

  • Virtually dust free, therefore restrictive and heavy respiratory protective equipment and extraction ventilation systems are not required.
  • Other people working in the vicinity are not affected.
  • It is water based and therefore harmless to personnel.
  • Supplied in premixed liquid form requiring no mixing.
  • Quality control is simpler and waste (rebound and dust in the air) is virtually eliminated.
  • Light and simple hand-held airless spraying equipment can be used.
  • No dragging of heavy hoses.

    Our innovation is the result of years of research in tunnel waterproofing and several more obtaining the certifications so it’s a great pleasure and a proud moment to see it in action
