 Located in Sydney’s Eastern Suburbs, this residential historical complex consisting of three levels of face brickwork, with garages to the front lower level of the property is of significant character and heritage. Years of Chloride ion penetration however, have resulted in the loss of integrity of the car park roof slabs. Bellmont was engaged to inspect and assess possible remedial measures. Our inspection revealed the presence of chloride ions within the concrete slab – well above the allowable threshold. The structural integrity of the slab and beams were deemed to be in a critical condition.  BellMont documented a remedial specification for the necessary remedial works and procured tenders from Sydney’s leading concrete repair contractors. Buildcorp was the successful tenderer and commenced with detailed propping and demolition of the structure in order to allow for the demolition of the concrete. Bellmont provided advice on propping of the building – whilst maintaining full functionality of the residential complex – other than the garage areas off course.
Interestingly, the intricate brickwork of the structure required for the new slab to be supported off cantilevered brickwork. The remedial design proposed by BellMont required for new shelf angles to be installed beneath the cantilevered bricks for additional support, along with the application of a penetrating migrating inhibitor to the existing concrete in order to protect against reinforcement corrosion for many years to come. The new concrete slab will be waterproofed and protected from water penetration for many years to come also.

Good work! Just to underline: when it comes to minor slab repairs concrete should not be used to fill cracks and holes. It will actually only perpetuate the issue, as you may deal with additional cracks and holes in this new concrete, further on down the line.

Concrete flaws aren't always obvious, such as visible cracks and uneven surfaces. It's possible that you'll just notice a minor shift in color or texture. If the color of your concrete changes, it could be an indication of a problem. This discolouration occurs when the protective coating on the surface of your concrete is stripped away by the elements. This alteration not only shortens the life of your concrete, but it can also cause major corrosion. To keep the concrete's surface protected, you'll need to apply a new layer of protective coating. 11/10/2023 09:48:30 pm

The engineer can suggest employing a polymer modified repair solution when concrete carbonation and low concrete cover are the problems. In this approach, the concrete surrounding the reinforcing bars is removed, the steel is cleaned, and then a steel primer and a polymer-modified substance are applied. The entire concrete surface may also be coated with a protective anti-carbonation coating. Before applying fresh concrete, the professionals may occasionally advise installing more reinforcing steel anodes; in more extreme circumstances, the steel may need to be replaced. 12/10/2023 10:41:46 pm

Concrete cancer, also known as concrete spalling or concrete degradation, occurs when the steel reinforcement within concrete structures corrodes, leading to the expansion and cracking of the surrounding concrete. This issue poses a significant challenge for maintaining the integrity and safety of buildings and infrastructure. When addressing concrete cancer, a crucial decision must be made: whether to repair the affected areas or to replace the entire structure. 24/7/2024 03:51:05 am
