Spalling Repair, Pyrmont
Located in the tranquil streets of Pyrmont, with one of the most fantastic city vistas in Sydney, this Quarry Master Drive building has been subject to major remedial renovations to rectify building fabric issues which have plagued the building since construction.
The fabric of the building was diagnosed with an extensive case of cracking and spalling render. The cause was identified by BELLMONT as being related to the poor method of isolation between differing interfacing facade materials.
Bellmont subsequently prepared a specification, procured the tenders and commissioned Polyseal as the successful remedial Builder.
The rectification works have been scheduled for completion by the end of 2012. Regular meetings with the building committee ensure the owners are continuously kept up-to-date with all project costing and programming issues.
The remedial works to the building fabric have involved the introduction of a separation barrier between external slab edge applied render and the brickwork above and below the slab edges. Such a barrier is required to ensure that materials with differing coefficients of thermal expansion are able to expand and contract independently of each other without the movement plane being bridged.
The works were (revised) completed before Christmas 2012—including a fresh façade coating to update and protect the reinforced concrete elements from the harsh marine environment.
