Waterproofing & Linings
Ensuring TBM Compression Gaskets Resist Natural Groundwater Pressure
Until recently, terminating cross-passage membranes to TBM segments had been one of the unsolved mysteries of tunnelling. Thanks to recent innovations in gaskets and pressure terminations, all hydrostatic forces can be resisted to ensure they meet the ‘no damp patches’ specification. The most challenging part of any cross-passage termination is ensuring the membrane connects and […]
Developing Membrane Termination Solutions to Deal with 3 Way Curvature in Cross Passages
Over the past 20 years, Bluey has completed waterproofing on hundreds of cross-passages, all of which have met the ‘no damp patches’ specification for rail infrastructure. All cross-passage entrances have curvature in three planes, making membrane installation, steel fixing and concreting far more complex than other tunnelling applications. The geometry adds particular challenges for the […]
When to Choose a Sheet Membrane vs Spray Membrane
A common question when it comes to waterproofing is which system to use. Sheet membrane or a liquid spray membrane? Liquid Spray Membrane – BluSeal TF05 BluSeal TF05, our spray applied membrane is designed to permanently consolidate and seal brickwork, concrete structures and rock excavations from gas and/or water transmission. The membrane is also […]
What Happens When You Bathe BluCem ZeoGlass In Acid for 2 Years?
In the early stages of the BluCem ZeoGlass (ZeoGlass) development and approval process, we teamed up with The University of Sydney to conduct a test program, to analyse the “leading” sewer lining shotcretes and see how they perform next to ZeoGlass. These commonly used products consist of a geopolymer based shotcrete, a calcium aluminate cement […]
The Checklist for Tunnel Waterproofing Success – Part 2
Engineering is an important part of the waterproofing process. Bluey employs qualified, full-time engineers that specialise in tunnel waterproofing. This second instalment to our project checklist has been made by them, to ensure that project design consultants understand the strict detailing that is required to work in accordance with World’s best practices. 11) Check for […]
