A blog by RAND Engineering & Architecture, DPC says:
"A problem we encounter all too often is a board operating in a reactive as opposed to proactive mode. If you don’t know the condition and the life expectancy of your building’s systems, you’re just going to be chasing crises as they occur. More crises means higher costs, higher stress, and lower quality on every project you undertake."
And we could not agree more. In this article, the building being expected isn't in too much strife but the property managers are wise enough to think ahead of the game and save them lots of heartache down the tracks.
Project: Bellmont Facade Engineering inspected the facade condition of a unit building in Ashfield.
The façade is generally in structurally adequate condition with a relatively small number of large concrete spalls evident in the slab edges of the balconies. Some minor “reinforcing bar ends” have corroded, and these will require repair also, but these are not considered to be a structural concern as yet.
The extent of corrosion is generally considered to be quite small and it is therefore our recommendation that early intervention and repair would provide maximum benefit to the owners.
- Concrete repairs to corroding steel reinforcement
- Render repairs
- Painting of slabs edges, balustrades and balcony soffits
- Replacement of spitter pipes with larger ones to allow easier drainage with less blockage
This issues of concrete spalling, corrosion, render/paint delamination and drainage/guttering works have been rectified.
As a result of being proactive, they have avoided even bigger issues and costs for the future. Be smart like them, call BellMont today to book an inspection (02) 9518 0775.
Bellmont to the rescue! The brick balustrades of this six unit apartment in Manly were a heavy burden to the concrete slab of the balcony.
Project: Bellmont Façade Engineering assessed the condition of the balcony slabs of 3 levels of residential units. There separation between the masonry balustrades at the ends of the balconies and the building which we believed to be caused by excessive deflection and rotation of the cantilevering concrete slab balcony. The rotation is more pronounced due to the cracking in the slab.
Additionally the cracking within the slab indicates a localised rotation that has contributed to the separation. This cracking provides a water ingress point to access the steel reinforcement in the slab. The top reinforcement is the critical strength reinforcement for cantilevering slabs and the condition of the reinforcement needs to be verified, however the cracking evident is an obvious precursor to reinforcement corrosion.
The movement of the metal balustrade indicates a loss of connection strength of the middle post. It is our opinion that the metal balustrade requires being replaced due to non-compliant strength and also height.
Recommendation: Replace brick balustrades with lighter aluminium balustrades to significantly reduce the loading on the concrete slab.
Status: WORK IN PROGRESS. The front of the building’s three balconies have been complete. Left to do are the three balconies to the rear of the building.
One of the most common building defects that our engineers come across day-to-day, are related to a lack of, or failure of waterproof membranes. You may be wondering, what exactly is a waterproof membrane and how do they help?
Well, as you may have thought, a waterproof membrane is something that is applied across the surface of the structure to prevent or lessen the effects that water may have on it. Why is it important to have an appropriate membrane though? The reasons are many, but the short answer is that water often leads to many difficult and expensive to fix problems within structures. Anything from the corrosion to the steel reinforcement in concrete, erosion, swelling of timber, to the delamination of materials and efflorescence.
One of the most common surfaces that these are applied to is concrete. Unlike what you may be thinking however, it is not only applied to areas that are at obvious risk of being affected by water, such as bathrooms and kitchens, but is usually applied universally. Other areas that are at particular risk include rooftops, balconies and basement areas.
There are a few different kinds of membranes, and its important to make sure that you apply the right one for the right job. Types of membranes, along with their general use include:

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 .
