Recently, BellMont was employed to undertake an inspection of this property by the strata committee in charge of it. During our diagnostic investigations, we discovered that there was a large amount of concrete in the structure that was unsuitable and in need of remediation.
As you can see below, the defects were quite extensive and required some consideration on how to best approach the task at hand. It was decided that the most effective method to repair the damage before it worsened and caused any catastrophic failures, was to use hand applied repair methods.
This approach involves:
Below are some pictures of this process.
Often these defects are a safety concern and will only worsen over time. So if you're concerned about your concrete, don't hesitate to contact us and start the process now.
Shotcrete also known as “gunite” is a widely used speciality concrete or mortar. Unlike the commonly used concrete, shotcrete is projected rapidly onto a prepared surface through a nozzle, rather than cured in a mixer and poured out onto a surface. Depending on the size of the project and amount of concrete required, shotcrete can be applied to a surface either manually or with the use of a machine,using a wet-mix or dry-mix spraying.
This solution is comprised of sand and gravel mixed with cement water. Supplemental fine material additives and chemical additives are then added to create the perfect consistency for the task required.
The use of shotcrete is beneficial for those within the construction industry as:
BellMont have experience with using shotcrete on number of projects which include the retaining wall rectification at Wardell Road, Earlwood, and the croft at Musgrave Street Mosman to name a few . If you are looking to use this material on your building and require our expertise, remember... our help is only a click away!
You may have heard the term Delamination before, but not really know exactly what it means. Delamination refers to a kind of mechanical failure in composite materials and steel. It’s characterised by the separation of a material into subsequent layers, therefore no longer being one solid object, but rather multiple; ultimately resulting in an unusable material.
With the large usage of composite and steel materials within the construction industry, it’s a fair concern. Part of what makes delamination so worrying is how insidious it is, in that it is a failure that occurs within the material; rarely seen on the surface making diagnosing the defect sometimes quite difficult.
The phenomenon can be caused due to a number of reasons and the impact it can have on a project can be devastating. Delamination causes the effected material(s) to lose a great deal of their strength, making their presence in a structure virtually useless.
Some common causes for Delamination are:
It is essential to stay vigilant when any defects present themselves in general, but even more so in the case of composite materials, as delamination usually appears alongside most other defects that affect these materials.
Most often, the only way to solve an issue involving delamination will involve the reconstruction/replacement of the material(s) that have delaminated.
There are a few ways to diagnose whether something is being affected by delamination however, most methods are destructive and involve invasive methodology to make the determination. A few non-destructive methods of ascertaining whether a material is being affected are to listen to the acoustics of the material in question. This can be done with the use of speciality equipment, or by getting someone who is experienced to generate a sound from the material (usually by tapping it with a hammer), and determining if the sound that comes back is ‘hollow’.
Delamination is a defect that we often come across and solve here at BellMont. If you’re in need of any diagnostic or remedial consultation do not hesitate to contact us so we can help you resolve your issues.

In Australia there are a number of historical buildings and locations, often referred to as ‘heritage sites’ or ‘heritage listings’, with systems put in place that govern how they are protected and maintained; such as the Burra Charter. The specifics for how something becomes a heritage site differs from state to state, but in general, an application must be made to the relevant governing bodies who will then determine whether the site in question will be listed as heritage.
Heritage listed sites are often quite old, usually built with materials that are no longer in production. This can make the maintenance on heritage listings fairly intricate and challenging, but there are a number of reasons why it is important to do so. If you don't keep on top of everything that needs doing, problems will pile up and often escalate, leading to more expensive work requiring to be undertaken.
Originally introduced in 1979, the Burra Charter was adopted for the protection and preservation of the historical mining town, Burra in South Australia. Since the its inception, numerous people have collaborated and worked to update it, ensuring that the charter continues to be a source of not just relevant theoretical information concerning the maintenance of all heritage buildings, but also the practical. To date, in Australia, it remains to be the chief source of information regarding the proper procedures that should be followed when undertaking works on heritage sites.
One of the more tangible reasons to make sure a heritage site is looked after and doesn’t fall into a state of disrepair, is that they can be great for promoting financial growth in an area. This is mostly due to tourism, as people will come from far and wide to see a little piece of history. This is especially important in more remote and rural areas of the country.
Another reason for the protection of heritage listings, is the preservation of history and culture. Often times these sites offer a snap-shot into the time period of their development, which offers a unique insight into what it was like back then. Architecture and building technologies of a period have always lent a unique perspective otherwise unobtainable into what a society would have been like.
We would be remiss to not mention that another reason for their protection is for an artistic sake, so that future generations can appreciate the marvels of yesteryear. Photographs and videos can only do so much, and it is unlikely that actually visiting a site and seeing it with your own eyes will ever be beaten.
Although many of these sites can be tricky to maintain and prevent dilapidation, don’t worry. Here at BellMont we have the benefit of almost 20 years’ experience in the field and we’re ready to help.
