Saint Barbara – The Protector of Tunnellers & Engineers

For many civil engineers across Australia and the World, December 4th is a special day. Today is World Tunnelling Day, recognising the great work tunnellers do to make our lives easier, whether it be through underground utilities, roads or public transport. The day also pays reverence to Saint Barbara, the patron saint of tunnellers, miners

Playing Our Part to Keep Australians On Time

Airports are the transport links that keep Australia soaring above the competition. When road, rail or sea transport is too timely or expensive, Australians take to the sky to get themselves and their cargo to the right destination, fast. According to the Department of Infrastructure, Regional Development and Cities, there were 63.5 million passengers carried

Building Trust Requires Consistent Results – BluGeo GRP60

Fuelled by product innovation and vigorous long-term testing, Australia’s civil industry has adopted a continuous improvement model in the past 30 years. As a result, Australia’s civil environments, including wastewater, tunnelling, ground stabilisation and concrete structures, are now world-class, in durability, strength and performance. Because of this, it’s become more common than not that specifiers

Does the Non-Shrink Grout ‘Unicorn’ Really Exist? – Part 2

Last week we discussed the different types of shrinkage and the dimensional stability of grout products. This week we will examine timing, testing and shrinkage compensation of grout. In the most part, engineers and applicators will observe shrinkage at a specific point in time. Test data will often refer to ‘28-day shrinkage’ which is the

Does the Non-Shrink Grout ‘Unicorn’ Really Exist? – Part 1

Just like the elusive unicorn, there’s a willingness to believe that non-shrink grouts really do exist. This imaginary grout not only lives on in the eyes of some engineers and end-users, but is repeatedly peddled by some of the leading suppliers of high-performance pre-packaged grout products. To determine once and for all if this ‘unicorn’

Concrete Repair: Why Modulus of Elasticity is the Most Critical Measure of Structural Performance

– By Daniel Bosco From the wide range of opinions about the best performing materials to the dozens of available products, the selection of concrete repair materials is a highly complex and challenging task. Depending on the application, the key drivers of performance can be categorised as either; durability, structural or aesthetic performance. This blog

The 5 Main Types of Concrete Failure – Here’s What You Need to Know

In the world of concrete repairs, the cause of the problem is not often visible, rather it is just a symptom of the real cause. Before any external faults show, stresses build up, internal chemical reactions may take place and unknown costs are already needed to repair the concealed failure. By the time it is
