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 – The Causes of Concrete Shrinkage
Failure to account for the causes of concrete 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 […]

Then & Now: Innovations of Tunnel Bolting & 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 […]
