13 ROOF MEMBRANE REPLACEMENTS IN EMERALD LAKES

The building manager and body corporate committee of a Southport building engaged NCR to remove decorative rock & decking & demolish planter boxes across two rooftops. After stripping the rooftops back to the concrete slab, the NCR team installed a UV-resistant waterproofing system.

The body corporate committee of a Mermaid Beach, QLD residential building engaged NCR to repair the corner column & beam. Due to the structural nature of the column & beam, NCR collaborated with BG&E Engineering, who provided the repair method for the structural & concrete spalling repairs that were completed by the NCR team.

NCR was contracted to remediate concrete spalling & install a new self-levelling, UV-resistant polyurethane waterproofing system on both the north and south towers of a building located in Surfers Paradise, QLD.

NCR was recently contracted by a high-rise residential building on the Gold Coast. They were experiencing water ingress through the control joints in the basement parking levels. This issue posed not only safety hazards but also caused damage to the paintwork of vehicles parked underground. If left unaddressed, continual water ingress could compromise the integrity of the concrete and reinforcement, potentially leading to further complications down the line. NCR removed the faulty drip trays, which had been previously installed in a bid to mitigate the excess water issue (not installed by NCR). The NCR team injected the joint with a waterproofing hydrophobic injection grout that fills the voids in the joints, eliminating water ingress and safeguarding the building from future damage.

NCR was engaged to reinstate the Waterproofing Membrane to approximately 100 square meters of planter boxes at an apartment complex on Kirra Hill. The scope of work consisted of the removal of existing vegetation and soil, the removal of the original waterproofing membrane and surface prep and the reinstatement of the new waterproofing system. Hydro-Excavation was utilised to remove the soil and drainage gravel following the removal of all vegetation. NCR engaged experienced sub-contractors to carry out this portion of the works. Once all vegetation on soil materials were removed the NCR team prepped all surfaces ready to install the Membrane system. All drainage points were cleared of roots, extra scupper holes were drilled into the planters to allow for greater drainage and a floor levelling product was applied to floor to ensure there were no low spots allowing for puddling. Once all the floor wall joints and cracks were routed, sealed and bandaged an Epoxy Primer was applied, followed by 2 Coates of a Class 3 High-Build Polyurethane Waterproofing membrane. Once NCR had complete the Waterproofing of the all the Planter Boxes, handover of the project to a Landscaping firm took place for the reinstatement of new gardens to round out the projects for our clients.

NCR were engage to remove the existing tiles and membrane from a 100m2 Balcony in Coolangatta. The balcony formed part of the roof structure for the unit below and water ingress had started to cause damage in several areas of the residence. Safety, as always was our major consideration given that the balustrade need to be removed in order to remove the existing tiles and membrane and then reinstall the new waterproofing and tiles. Utilising our trusted sub-contractors, a full scaffolding system was erected to insure the area was safe for work to commence. The system also provided protection from debris falling below toward other residences. Demolition and grinding of the tile and membrane removed all reminisce of the previous membrane and following this all cracks were routed out & sealed and a full 3 coat membrane system was reinstalled. This included detailing of surface defects, bandaging to floor wall joints and the installation of a waterproofing upturn to the columns and floor wall joint to insure a watertight system. There previously had not been a skirting tile nor any upturn waterproofing applied to the floor wall joints and NCR identified this as a potential risk for water ingress. Following the waterproofing system being installed the NCR team then laid 450 x 450 outdoor tiles in a neutral tone were reinstalled to the area and the balustrade was then reinstalled. A beed of uv resistant silicone was then applied to the top perimeter of the skirting tiles, balustrade feet and to the sliding doors where the tiling met the doors ensuring all possible areas for water ingress were addressed.

National Construction & Remedial (NCR) were contracted to complete concrete spalling repairs to four balcony soffit's and replace metal posts at Golden Sands On The Beach in Main Beach, Gold Coast.

National Construction & Remedial (NCR) were contracted to replace three rooftop waterproofing membranes on Bel Air on Broadbeach, totalling 700 square meters. The existing rooftop membranes were ground back to concrete, and a four-coat UV stable trafficable membrane was installed.

National Construction & Remedial (NCR) were contracted to remove and replace the existing tiles, dividing fence and roof membrane from a Broadbeach apartment building. This job required more planning and coordinating due to the logistics of getting 200m2 of tiles and membrane, as well as a dividing wall off the rooftop. The NCR solution was to use a crane. The 200m2 of tiles and membrane was removed and loaded into crane safe bags and were lifted off the roof by a crane. To maximise time and money for our client we managed to utilise the crane to lift up the new tiles, grout, screed, waterproofing membrane materials and the new fence panels. The NCR team coordinated hire of the crane and traffic control, as well as ensuring the council permit and police permits were organised. To combat water pooling issues on the roof, the NCR team created fall and drainage to move the rain water off the roof. A new polyurethane waterproofing membrane was applied. The roof top was finished off with modern neutral grey tiles and a white aluminium louver angled fence to divide the two apartments with roof top access.
