"rainwater goods roof drainage systems"

The 52mm drainage cell has been used as normally in two guises. Firstly as a TurfcellTM grass reinforcement such as at Natural Designer Homes , a display home in Casuarina NSW. The photograph of the driveway is from about 1year ago, some 4 years from installation. As there are several cars in the family as well as work trucks the installation looks quite good.Secondly as a Gravel cellTM gravel retainer, such as that used at Leaf and Limb Nursery in Kin Kin Qld., where they use the 52mm cell in the walkways as this makes it easier for them to run the trolley through the gravel.However there is a third use for the 52mm drainage cell. That is as walk ways in mining camps. Traymark Industrial Caravans make the vans for accommodation for the workers and Atlantis® 52mm cells are supplied with each van to be used as a walk way to keep workers out of the mud and dirt when at their accommodation..Secondly as a Gravel cellTM gravel retainer, such as that used at Leaf and Limb Nursery in Kin Kin Qld., where they use the 52mm cell in the walkways as this makes it easier for them to run the trolley through the gravel.Now for another use: a client already was successfully using our 52mm drainage cell as reinforcement for parking bays beside a river and in August 2011, it occurred to him that he could extend the parking area into a boat ramp. Our 52mm drainage cell is made from recycled polypropylene with U. V. protection, in sheets being 480mm x 260mm x 52mm.Two tracks, being 0.96m in width were connected to the 52mm drainage cell in the parking area and also were secured by metal hook pegs to the drainage cell of the parking area. The tracks lead to a full width ramp (2.88m in width) into the water.To prevent the ramp from sinking fully into the silt, the ramp and adjacent section of the two tracks are formed by two layers of 52mm drainage cell connected to each other by cable ties. Metal hook pegs were also used to assist in holding the ramp in position.We contacted our client in August 2017 and he is very happy with the boat ramp which is still in use despite several floods, and constant exposure to the elements.Thus the high load bearing of approximately 4000t/sq. M and the long useful life of the 52mm drainage cell has permitted the 52mm drainage cell to be used and still being used in many ways.

Project Location: Amberley, Queensland, AUSTRALIA.In Amberley is one of the largest base facilities in Australia. The redevelopment works are valued at AU$331.5 million. New construction and refurbishment works to be undertaken include newliving-in accommodation, maintenance facilities, storage, working and training accommodation, a combined mess and a new physical fitness centre.The site is owned by an Australian Government Department. The Atlantis® Turf Cell® was supplied by Atlantis and was installed by Kennedy Projects Group in April 2009. The system is located at the playing fields on the south-western corner of Gannet St and Rosewood Road, Amberley, QLD.A vegetated swale surrounds the playing field. The swale is an open, shallow channel designed to slow runoff, filter it, and promote infiltration into the ground. Excess water moving through the soil profile is captured by Atlantis® Matrix® Tank – Single modules. The use of a swale to collected water results in smaller runoff volumes, lower peak discharge rates and cleaner runoff. The vegetation in swales, usually thick grass, helps to trap pollutants such as suspended solids and trace metals. The Atlantis Matrix modules extend 3m (10ft) wide under the swale for 110m (360ft).Water collected by the swale is collected in a stormwater harvesting tank located adjacent to the north-western corner of the playing field. Perforated corrugated plastic pipes used as subsurface drainage pipes extend for 1560m (5110ft) is also collected by the stormwater harvesting tank.The stormwater harvesting tank is located subsurface and is constructed of a heavy duty low density polyethylene liner and non woven geotextile surrounding Atlantis® Matrix® Tank - Double modules. The Atlantis stormwater tank has a 4,100m3 (144,80 ft3) capacity. Water collected by the swale and stormwater tank system is used for irrigation of the sports field.The Atlantis stormwater tank has eight (8) cleanout / inspection ports placed through the systems. A 1200mm (4ft) dia. wet well with bolt down lids has been installed adjacent to the tank serves as a pump out pit. The overflow from the tank has a 15m (50ft) long x 400mm (1.3ft) deep spill way with scour protection into an adjacent creek.

COLLABORATIONArchitect: Neeson Murcutt ArchitectsDeveloper: Surf Life Saving NSWBRIEFNeeson Murcutt Architects needed a solution that would protect the glazed ceramic tile roof on the $2.2 million rebuild of the Old Kempsey-Crescent Head Surf Life Saving Club. They wanted to avoid grime and salt accumulation on the roof system with minimal maintenance from the volunteers and to reduce maintenance costs.The architect designed the outside surfaces so they would be durable in the marine environment and easy to maintain. With difficult access to the roof, the builders decided on ECOCLEAN to help with maintenance and cleaning of glazed ceramic roofingMATERIAL & APPLICATIONECOCLEAN Porosity SealerECOCLEAN Self-Cleaning CoatingOUTCOMEUsing the power of daylight, rainwater and dew, ECOCLEAN created a self-cleaning roof that continually breaks down algae, mould and organic matter, which can cause unsightly stains.

CASE STUDYS LISTED ABOVE IN PICTURE 4

APPLICATION: Road CellPROJECT LOCATION: Chan Chan PeruPROJECT DETAILS: Protecting Walkways and Preventing erosionPROJECT COMPLETION: Sep 2016Chan Chan, the largest City of the pre-Columbian era in South America is now an archaeological site in La Libertad Region, 5 kilometres west of Trujillo Peru. Chan Chan is located in the mouth of the Moche Valley and was the capital of the historical empire of the Chimor from 900 to1470, when they were defeated and incorporated into the Inca Empire. The city Chan Chan spanned 20km2 and had a dense urban centre of 6 km2.The increasing popularity of the site forced the authorities to consider how to protect the walkways and to provide drainage, to remove rain water from the site to prevent erosion. The solution was to use the Atlantis® Road CellTM 53mm drainage cell. This installation made Chan Chan the second World Heritage site in all of Peru to have a highly technical system of protection of the original pavement installed and it covered almost the entire tourist circuit with the exception of the funeral zone.A layer of water proof membrane was laid down on the walkway and the the Atlantis® Road CellTM 53mm drainage cells were clipped together on the water proof membrane and filled with gravel. Thus providing protection for the walkway and also providing a drain for directing rain water away from the archaeological site to ameliorate erosion. Also it facilitated the access of visitors, especially those with disabilities, by providing a firm stable walk way.In all 1,700 m2 of the Atlantis® Road CellTM 53mm drainage cell were laid, and filled with gravel.

APPLICATION: 30mm Wall PanelsPROJECT LOCATION: Redland Bay QldPROJECT DETAILS: Seeping WallsPROJECT COMPLETION: Jun 2011Atlantis fixing old water seepage problemsA property in Redland Bay Qld was having water seeping through the walls of the lower part of the property, which was below ground level.A trench was excavated to expose the walls which were below ground level, and the walls were allowed to dry out.A waterproof membrane was affixed to the wall and Atlantis® Flo- pipe® geotextile wrapped perforated pipes were clicked together and laid on top of the lower fold of the water proof membrane.A run of Atlantis® Flo-cell® drainage cells was sat on the perforated pipes and taped to the waterproof membrane, to extend along the length of the trench. The run of drainage cells was covered in hydrophilic geotextile and the trench filled in with compacted gravel.The water proof membrane formed a barrier to prevent water from contacting the walls of the property, while the 30mm drainage cell formed an air gap to relieve any hydrostatic pressure on the water proof membrane. Any water entering the drainage cell falls into the perforated pipe where it is taken away. This arrangement has been used, literally, thousands of time to overcome or prevent this seepage problem.

APPLICATION: 52mm Drainage Cell.PROJECT LOCATION: Silkstone Qld.PROJECT DETAILS: Parking Bays at the Silkstone Primary School.PROJECT COMPLETION: Sep 2013.Atlantis system saves big old tree.At Silkstone State school Qld. a contentious issue arose. The school required car parking and a sealed one at that. But, in the proposed car park was a huge old tree. The tree could be cut down and the roots dug out or the tree couldbe left, with open soil above the root system to allow for infiltration to keep the tree healthy; but this would lose atleast six car spaces. What was to be done?The answer turned out to be simple – keep the tree, but surround the tree with Atlantis® Gravel Cell™ 52mm cells.Hence while the rest of the car park was sealed, the areaaround the tree was prepared and the 52mm cells werelaid and clipped together there and filled with 10mmgravel. This area was of sufficient size to provide 3 carplaces on each side of the tree and a driveway in frontof the tree, while at the same time allowing rainfall toinfiltrate through the gravel into the root system.Thus we had a win-win situation. Not only was the treesaved, and money saved on not having to remove it, butthe root system of the tree was protected by the GravelCell™ system, and six extra car spaces were created.

COLLABORATIONArchitect: ThomsonAdsett in collaboration with nettletontribeBuilder: L.U.SimonDeveloper: Deakin UniversityBRIEFThe Waterfront campus for Deakin University at Geelong celebrates the “individual” student through the prominent white precast concrete. The client on this project wanted to ensure that over time the white concrete stayed pristine – looking as good as new – without expensive cleaning and maintenance costs.MATERIAL & APPLICATIONECOCLEAN Porosity SealerECOCLEAN Self-Cleaning CoatingOUTCOMEOur ECOCLEAN Self-Cleaning system has been applied to the concrete to preserve the appearance of this building’s prominent facade. This significantly reduces cleaning and maintenance costs making this a cost-effective and net positive environmental solution.

This project is a great example where the client wanted to realise the instant savings of Con-form Group’s engineer certified, rafter mounted system, over costly traditional mounting systems.With a mixture of our EasyMech MR (purlin-mounted), and Span+ (rafter-mounted), HVAC platforms - the client was able to successfully mount all mechanical units across the roof of this mixed-use development in Tasmania.Spanning over 9 metres, this retrofitted Span+ (rafter-mounted), installation answered the clients brief in more ways than one.Rated to 2.5kPa and attached to Con-form Groups proprietary steel stub columns – this platform and it’s screens were retrofitted to the roof of this shopping centre within 2 days.Paired with our Louvre airflow and Classic Screen Walls.

THE CHALLENGE: House 30+ new HVAC&R mechanical plant equipment and vents. Retrofitted to the roof of a large, multi-level shopping centre without interrupting regular retail operations.THE SOLUTION: We supplied over 30 EasyMech MR (purlin mount) and Span+ (rafter mount), HVACR platforms in Kit form.Our Span+ (rafter-mount) system, was designed to be 100% penetration-free and installed on the surface of the roof over the rafters.We also supplied walkways, up & overs, and ladders – all in Kit form! Providing savings in cost and time.

Challenge750m2 roof with a large quantity of vents, air conditioning units and other equipment on the roof. Add to this problem damaged aging torch membrane, combined with Governments regulations regarding solar absorption and reflectivity of the building posed a real challenge for the applicator when determining a solution for the job.A second challenge for this job is the location of the building was located in the built up CBD of Parramatta with neighbours in close proximity, which meant the solution needed to be neighbourhood friendly.SolutionGiven the complexity of solution required for such a job AlphaGuard BIO is the only product which ticks all the boxes. AlphaGuard BIO is an extremely high performing composite waterproofing system, designed with a focus on roofing restoration. Due to AlphaGuard BIO being a liquid, it makes it ideal for jobs where there are machinery on the roof which needs to be worked around.AlphaGuard BIO has the ability to be installed over various existing roofing membranes in order to minimise tenant disruption and extend the life of the roof for an additional 20 years.It cures to form a durable rubber membrane surface that provides a lasting and easy-to clean waterproof coating. AlphaGuard BIO may be used to apply a seamless, monolithic waterproof membrane to concrete, primed metal, or existing roofing membrane surfaces.AlphaGuard BIO’s low VOC will minimise offensive odours to current tenants and applicators. The white top coat provides high solar reflectance, reducing the building’s operation costs and complying with Section J1.3(b) of the 2019 NCC.

Snapper Creek Car Park was developed as an environmentally friendly permeable car park. As such the Atlantis® Turf CellTM and Atlantis® Gravel CellTM systems were chosen, to provide gravel driveways and grass parking areas, thus preventing compaction of the soil and to protect the grass and to stabilize the gravel and provide a permeable car park.The parking areas were divided into car only parking and car & trailer parking.The area, consisting of natural sandy material, was excavated to a depth of 300mm, and a tensar grid was placed into the excavation and the excavated material placed back on top of the tensar grid and compacted.A layer of 100mm of gravel was then place on the areas where the Atlantis® Gravel CellTM modules were to be used and the Atlantis® Gravel cellTM modules positioned thereon and filled with gravel.The Atlantis® Turf CellTM modules were installed and filled with soil and then the area was grass seeded; no turf was used. The project was completed in mid 2014 and was at that stage semi grassed and in use.The project required 4,300sq. m of Atlantis® 52mm drainage cell, which are 480mm x 260mm x 52mm panels and have a rigid interlocking clipping system and are made from recycled polypropylene.In August 2017, the operators of the car park, which is still operating, were contacted and they stated that they were extremely happy with the condition of the car park, even though it has heavy traffic as there is a boat ramp there, and some areas have been flooded by Snapper Creek.The Atlantis® Turf CellTM & Atlantis® Gravel CellTM systems are specifically suited for car parks, access roads, aircraft taxiways and helicopter landing pads as it has the following features:a high load bearing of approximately 4000t/sq. M;protects the root system from compaction, while allow for vigorous horizontal and vertical root growth;permits surface water absorption and infiltration; andhave a long use life.

Harmful compounds are continuously broken down when they come into contact with a coated surface in addition to benefiting from graffiti resistance.Testimonial“This is an example of our functional and protective coatings removing the barriers to having white or fair-faced concrete or cladding in building designs. Their self-cleaning, anti-carbonation, anti-fungal, and graffiti resistant properties mean buildings look as good as new, enabling fresher and lighter colours to be more prevalent in our built environment.”Tony Watling, CEO ECOTONE & ECOCLEAN, Australia & New Zealand

Designed by Richard Lutze. This project won the 2017 Building Designers Association of Australia Design Award for Public Buildings/Structures. The building has been designed with modern conveniences while also ensuring a sustainable passive layout, with large openable areas facing north overlooking rural vistas, providing good natural light and ventilation to the classrooms and laboratory through the use of Breezway Louvre Windows.

Rondo supported Maxcon Pty Ltd through contractor L&Y Commercial for this project incorporating two 26 and 36 story residential towers of 551 apartments, an Art Series Hotel with 90 rooms, retail spaces and serviced offices. Due to the large-scale nature of the build, our customer was very satisfied with Rondo’s ability to provide quick turnaround times for crane lifts as well as our efficient and effective operation of installation and delivery of goods on site, on time.

Termi Home & Commercial (SA) were proud to be a part of the historic Norwood Oval Redevelopment project in Adelaide, South Australia. As one of the most iconic football grounds in Adelaide only a non chemical termite management solution would do. We designed and installed the Termimesh System keeping in mind both the historical significance and the new facilities.The suitability of the Termimesh system for this project is based on its flexibility, which was necessary due to complex external geometry of the new construction and integration with the existing buildings. This presented challenges in performing remedial work. For example the Sir Edwin Smith Grandstand is heritage listed meaning minimal work was allowed to the external façade. This is where the strength of our termite management system lies. It can be customised for each individual project. Our estimating and design team will work alongside the architect, marking up plans and explaining how the system is applied to the design. Which in the case of the Norwood Oval was extremely important. We are on hand during the construction phase to iron out any challenges that may arise ensuring the installation process is simple, smooth and straightforward.Termimesh has maintained our position as market leader in termite protection in the South Australian construction industry for over 25 years, with a strong domestic and commercial portfolio. We are one of few companies that are triple certified to AS48001, ISO9001 and ISO14001 which delivers additional peace of mind for our clients.CONSTRUCTION TEAMSchiavello ConstructionOur team has a good relationship with the lead contractor, Schiavello, having worked on past projects together.

The Chadstone Shopping Centre in Melbourne, Australia, is an amazing piece of engineering and architecture. With its stunning gridshell glass roof, the extended building is now the largest enclosed shopping centre in the Southern Hemisphere.

Designed by Smart Design Studio, the building is an honest layering of old and new as expressed by the raw treatment of the exterior façade through to the smooth, modern interior. The rooftop addition connects the double-height banks of glass Breezway Louvres with an articulated aluminium roof folding down as a screen to the back of the building. The end result successfully incorporates flexible and functional office interiors and a two-bedroom rooftop apartment within a rigorously controlled contemporary architecture of old and new.

Warwick Hotel Rittenhouse Square in Philadelphia, PA, is quite satisfied with the functioning and cost savings of their Boon Edam Tournex revolving door. The Tournex is an example of a classic automatic revolving door and is designed to handle high capacity applications. The historic building housing the Warwick Hotel Rittenhouse Square originally had a manual revolving door flush with the building’s facade. Somewhere along the way, it was decided to remove the relatively smaller gauge revolving door and replace the entrance with a double set of sliding doors. “Our HVAC system was designed for a revolving door entrance,” said Ray Hewitt, the hotel’s Director of Engineering, “we wanted to put a revolving door back in to address the negative pressure we were experiencing in the lobby.” That negative pressure was pulling in cold air during the winter months, and cooled, conditioned air was escaping out the double doors in the summer. During a complete lobby renovation project a few years back, designers worked to return to a revolving door lobby entrance. Because the Warwick is in a historic building, they could not change the facade of the building, so they pushed the entire entrance into the lobby itself. The architects and the designer chose a 12’ diameter Boon Edam Tournex automatic revolving door, with three door wings and a highly polished (mirror) stainless steel finish. The Boon Edam door is enclosed in a stylish glass cube, accented with purple neon lighting. Now, those entering the hotel first pass through a double set of sliding doors at the building envelope, leading to the revolving door. Swing doors are also available on either side of the revolving door to enter the lobby itself. The effect of the sliding doors and the revolving door in a cube is to virtually eliminate air flow from outside in, and vice versa. The Warwick has 301 hotel rooms and 106 permanent residents. On any given day, between guests, residents, staff, and visitors, up to 1000 people are passing through the entrance. Since the installation of the new entrance, the effect has been night and day—guest and visitors utilise the lobby space longer and in greater numbers. A big community table is usually filled all day long and the lobby is accented with attractive fireplaces. The hotel lobby also offers two full service food and beverage outlets (Bluestone Lane & Prime Rib Steakhouse), with a third to be announced sometime this year. In addition to a now grand sense of arrival and more useable, comfortable space, the new entrance is also paying dividends on energy savings. “With the old entrance, our HVAC was running constantly, it could not keep up. Now, the unit can shut down periodically; that’s good for the health of the system, and we’re seeing substantial savings on energy bills,” said Hewitt. The Boon Edam revolving door has an important feature for installations like a hotel or large office building—in the event of an emergency, the doors stop and the wings can be “book folded” to create wide open ingress and egress. The hotel has a maintenance contract with Advanced Door, but since installation the Boon Edam revolving door has been virtually trouble free.

Designed by Benson McCormack Architects and built by Hone Constructions. The curved glass elements seen at the ground level entry shopfronts and in the feature penthouse facades are key to the undulating design which becomes the signature for the “Wave” Apartments building. In particular the projecting curved façade at each end of the penthouse roof level is a major element of the architectural design and a feature that can be seen from afar. The sweep of the concrete rood appears to float above the skin of curved glass creating a dramatic visual effect.

Rondo has so far provided over 10,000lm of various wall and ceiling systems, including Rondo Steel Stud Drywall Framing System, KEY-LOCK Suspended Ceiling System and DUO Exposed Grid Ceiling System. More complicated designs arose when it was discovered that the high cyclonic winds would affect the facade of the building.

his project saw a number of our systems installed including six of our EasyMech MR platforms in varying sizes, ScreentoRoof MR system, ClassicScreen Walls and our Acoustic+ screen wall system.We consulted with the team from design to install to ensure a smooth and seamless experience.For more information on our systems, contact our Customer Care Team today.

The KEYLOCK Concealed Suspended Ceiling System, Steel Stud and Track Wall Framing System, and XPRESS Drywall Grid Ceiling System have been integrated throughout the project. Rondo’s long-term relationship with Ceiling & Wall Contractors enables the project to run smoothly and the onsite coordination is exemplary.

Rondo provided a range of market leading wall and ceiling systems for both buildings 3 and 4. Our KEYLOCK Concealed Suspended Ceiling System and Steel Stud and Track Wall Framing System were used for the internal fit out, completed by AUSTRAL Interiors. SMTM Projects used our 1.15 BMT Stud and Track with top hats.

As the project was located in Hobart, it required the project team including Rondo to work together to be organised and keep a clear path of communication. This resulted in the full specification being completed early in the process, the specification included Rondo Wall Stud, KEY LOCK Ceiling Systems, DUO Ceiling Systems, External Soffit Systems and our extensive knowledge on seismic design.

The entire building also featured ceilings acoustically isolated from the old structure where heavy duty isolators were required to be incorporated into the Rondo KEY-LOCK Concealed Suspension System. Similarly Rondo had to design a supplementary suspension system beneath these ceilings to accept a secondary system to support some services and particularly architectural feature ceiling beneath.

With a demand for leading scientific research facilities growing year upon year, the South Australian Government commissioned the development of the South Australian Health & Medical Research Institute (SAHMRI). Since the project commenced in 2010, Rondo has supplied our KEY-LOCK Suspended Ceiling System, Steel Stud and Track, DUO Exposed Grid Ceiling System, PANTHER Access Panels, Shaftwall and Walk-About Trafficable Ceiling System.

he developments $247.3m price tag makes it marginally more expensive than the $246m Adelaide University building next door. HIB will house the Centre for Cancer Biology and UniSA’s pharmacy school, with 450 researchers between them. Rondo’s involvement included providing ceiling and wall systems using our Shaftwall One-Way Erected System, KEY-LOCK Concealed Ceiling System and PANTHER Access Panels to create the desired effect.

Rondo was called upon to supply our market leading Seismic Wall and Ceiling System including Steel Stud & Track Drywall Framing, KEY-LOCK Concealed Suspended Ceilings, and DUO Exposed Grid Ceiling Systems.

The refurbishment of the Victoria Gardens shopping centre designed by Colab Design Studio uses Sculpform's Aluminium Click-on Batten system to create a stunning curved Oculus, along with feature walls and ceilings throughout the centre. Sculptform’s Click-on batten system provided a unique solution that could be customised to address the incredibly complex geometry of the existing architecture. Being able to use the same system for the mall cladding, mall ceiling installations and the oculus cladding ensured absolute consistency across the entire centre.

The project has called on our Technical Services Team for wall and ceiling designs, with significant quantities of Rondo systems used in the project including Rondo Stud and Track, KEY-LOCK Concealed Suspended Ceiling Systems and PANTHER Access Panels.

For instance, Superior faced the challenge of creating curved detailed bulkheads and feature ceilings. However, with Rondo’s help using a hybrid of the Rondo KEY-LOCK Concealed Ceiling System and Stud & Track Wall Framing System, they managed to create a great outcome.

The $11.3 million dollar renovation of Lambton Square required Rondo product throughout including our Key-Lock Concealed Ceiling System, Steel Stud Wall framing system and various other Rondo components for the fixing of plasterboard and feature panels.
