APPLICATION: 52mm Turf CellPROJECT LOCATION: North Ryde NSWPROJECT DETAILS: Macquarie University Permeable Overflow Car ParkPROJECT COMPLETION: March 2017Established in 1964, Macquarie University began as a bold experiment in higher education. Built to break from traditions: to be distinctive, progressive, and to be transformational. Today its pioneering history continues to be a source of inspiration as they celebrate their place among the best and brightest minds.When Macquarie University’s existing cark park became too small for the amount of cars now using it, it was decided to construct an overflow car park. However, not just any car park, but in keeping with their innovative thinking, an environmentally friendly permeable car park. Of course the Atlantis® Turf CellTM system was chosen, so that turf covered parking spaces could be provided.The project required 9,843sq. m of Atlantis® Turf CellTM system, which is constructed from 480mm x 260mm x 52mm panels and has a rigid interlocking clipping system and is made from high quality recycled polypropylene. The project was undertaken by J & G Excavations and Asphalting (NSW) Pty Ltd.The Turf CellTM cells were laid on a bed of permeable soil, and filled with sandy soil and turf was then placed on top of the linked Atlantis® Turf CellTM cells and rolled with a heavy roller to press the roots into the soil in the cells, where they were protected from compaction and could grow freely both horizontally and vertically.The Turf CellTM system is another Atlantis invention, and is 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 of grass from compaction, while allow for vigorous horizontal and vertical root growth;permits surface water absorption and infiltration;has a long use life; andaesthetically, the system allows the grass to fill in completely, creating a lush lawn with an invisible reinforcement structure.

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.

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.

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.

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.

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.

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.
