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 […]

How to Apply a Structural Shotcrete Liner and A Protective Coating in A Single Step

In the past, relining a highly acid environment has required two essential steps: 1) A layer of structural shotcrete is applied to improve the asset’s overall strength. 2) A sacrificial CAC protective coating is applied to ensure the structure’s durability by resisting sulphuric acid and other highly corrosive chemicals. The interchanging of teams, machinery and […]

Shrinkage – Part 3: How to Achieve Shrinkage Compensation

Successful shrinkage compensation coincides with each phase of shrinkage. In other words, the magnitude of expansion and the timing of occurrence should be equivalent to the predicted shrinkage for each stage of the grout or concrete’s life. To achieve shrinkage compensation, we use a variety of  techniques and products.         1. Reducing […]

Shrinkage: Part 2 – Selecting the Right Test Method to Measure Shrinkage

We are sure that you have heard the term ‘non-shrink grout’ and it is often backed up by the term Class C or a reference to ASTM C621. What Do These Terms Mean? Well for a start, there is no such thing as ‘non-shrink grout’ and further to that, ASTM C621 doesn’t even exist! It […]

Shrinkage: Part 1 – Defining the Causes of Shrinkage

Failure to account for shrinkage can lead to tension, cracks or even result in failure of the whole structure.   In the next three-part blog series, we’ll take a detailed look at shrinkage and how we compensate against it to deliver consistent, controlled products in all temperatures and conditions. What is Shrinkage? Shrinkage measures the […]

“We Operate Like A Formula One Pit Crew, But for Fast Set Concrete” – Nick A, NA Group

The current aeroplane curfew for most Australian International Airports is from 11pm to 6am. This means that critical works such as runway slab replacements must be painstakingly planned and executed to ensure the runway can be returned to service and be capable of supporting aeroplanes within a seven-hour window. Nick Agromopolous, Director for NA Group, […]

Stronger Together – MBCC Group acquires Bluey Technologies

  At a time when MB Solutions Australia was re-establishing itself in Australia as a market leader for specialty construction chemicals, Bluey was also looking for ways to continue its expansion and support its growth efforts both locally and abroad. The solution for both companies has come in the form of an acquisition that was […]

Get it Right the First Time – The Art of Concrete Protection

As a trusted supplier, we understand that we have a responsibility to protect and preserve the natural and built environment. This means weighing up economic, social and environmental impacts of every project we work on. In the article below we discuss the importance of concrete protection on the environment and how Bluey assists projects in […]

Rock Strata – Looks Good from Afar, But is Far From Good to Work With

When looking at layers of exposed bedrock, you can often see beautiful striations and colour changes as one line of rock gives way to the next. Known as strata, these layers are formed over vast time periods and are deposited by hydrologic and geologic processes. While exposed strata can be truly picturesque, it can also […]

Then and Now – Innovations of Tunnel Bolting and Grouting

When it comes to safety in any tunnelling or underground project, rock bolting is an effective mechanism for long and short-term tunnel rock support. When work sites require a long-term solution, rock bolting and bolt grouting are used together to ensure the maximum stability and design life of a structure. Before modern rock bolting, underground […]
