The TerraFirm retaining panel range INNOVATIVE by ModularWalls has been a leading solution RETAINING PANEL in residential development projects for years, utilising composite SAVES DEVELOPER panel technology to provide a cost-effective, durable alternative to traditional concrete. In recent TIME AND MONEY years, ModularWalls have expanded their product range and further developed their retaining panels to cater for the commercial and industrial market. TerraFirmXL, a heavy- duty commercial grade panel, has retaining capabilities of up to 3.0 metres, whilst bearing surcharge live loads of up to 10kPa. This innovative commercial retaining panel was the key solution in a townhouse development undertaken by Amcon in Maryland, NSW, that required a timely, cost- effective alternative to a gabion retaining wall. The developer required a premium solution to complement the architectural design that fit within the budget and timeline. Gabion baskets are very slow to build and would have encroached on the footings for the townhouses. The option for a rendered, core- filled block wall was also unsuitable, due to budget restraints and the tight build schedule. TerraFirmXL retaining panels offered an aesthetically pleasing, cost-effective solution with a rapid installation time of two weeks, due to its modular design. This was less than half of the five-week installation of a core-filled block or gabion wall, which would have slowed down the build of the townhouses and caused major disruption onsite. Ultimately, the developer was able to achieve a superior solution for a lower cost in a shorter timeframe. “It was the opposite to gabion walls – little space, not labour intensive and was quick and price comparable,” states Mr Paul Murdoch of Amcon. “Install went well and it was very quick, which was the main advantage. Lightweight and uncomplicated, with minimal diversity of trades required. I will be using it again when needed.” The TerraFirmXL retaining wall ran for 50m in length and retained 3.0m in height, with townhouses constructed within 1.5m of the wall. Full design and engineering was supplied by ModularWalls, with their in-house team collaborating with contractors and the developer for a smooth, efficient process. Incorporating heavy duty reinforcement within a high-density EPS core and superior

providing higher efficiency in transportation methods – trucks are packed to volume, rather than weight. Due to less trucks being on the road and having lighter materials to handle during installation on site, risk factors are also reduced for the project. TerraFirm panels can be used for either a stand-alone retaining wall or within a fully integrated, multi-purpose modular wall, enabling developers to incorporate noise prevention and earth retaining functions into a single, seamless wall structure. This saves a significant amount of time, money and space by avoiding the need to build a separate retaining wall or enlisting a separate team of contractors. By integrating the TerraFirm panels with other ModularWalls panel products, such as EnduroMax or AcoustiMax, a multipurpose wall solution can be achieved.

In a refinery, concrete flooring was sufficient in the past but many now require easy to clean, seamless leak proof floors to minimise dust build up, making 11-50 FR an ideal material to use. Applied to an appropriate thickness, the polyurea coating can withstand tracked vehicle traffic, forklift operations and heavy loads and reduces noise from vibration and impact. However, Idzes added that because of the range of substrates, customers should test a small section to determine the suitability of these products for their own particular application. “When considering a coating you have to think about its physical characteristics as well as the physical environment where it will be used,” he stated.

In fact, he says his company specifies the elbows as an alternative whenever a client’s design calls for long-sweep elbows. The policy evolved after receiving ongoing client complaints about prior uses of long-sweep elbows requiring excessive maintenance downtime for patching or replacing worn-through ells, or clogging of hygroscopic materials. Ober’s company has evolved its own installation procedures based on the historic longevity of the deflection elbow's wear resistance in its clients’ plant applications. “We will frequently hot-dip the flanged piping and paint the elbows with a zinc-metal cold galvanising compound, because once they go up they’re going to stay there for more than a decade,” Ober explains. Vortex chamber reduces elbow wear, material degradation, installation space A unique characteristic of the HammerTek Smart Elbow™ design is a nearly spherical vortex chamber designed into the curve of the elbow. Key parameters allow the chamber to capture a portion of the airflow PNEUMATIC traveling through the line and cause it to double back into the material stream, creating a deflection zone that minimises both elbow wear and product degradation.

The company optimises the parameters of conveying systems on an individual basis by applying the performance characteristics of the Smart Elbow™ design to decrease aeration and increase density, thereby reducing the time a transport driver must wait for materials to settle as the silo fills up. Ober notes that some bulk transport drivers were initially reluctant to hook into his plant designs, for fear that the pneumatic transport lines with short-radius elbows would plug up with material. “Some of those drivers were not just sceptical, they downright refused to connect without a call to the dispatcher or to us,” he relates.

TRANSITIONING LAND USE That’s seen a change in land use in the city circles and close-by inner suburbs. In many Australian cities, land that was formerly occupied by single houses, offices or factories, is now well entrenched in a transition of redevelopment. Very often it’s a two-pronged approach.

Importantly, they should be made in Australia to support local economies - in factories where production is efficient, quality is high, waste is minimal and worker safety is paramount. They should not require protective treatment with chemicals, nor should they emit toxic gases in the sun. While the breadth of precast products is vastly more extensive, precast equally has an important place in open outdoor spaces and excels at meeting sustainability, form and function requirements. It’s long lasting, needs minimal on-going maintenance, is robust, durable and locally made in purpose-built factories. While bollards, wheel stops and barriers can have a functional role, other items like monuments, feature walls, planter boxes, tables and chairs or water features can be both functional and decorative.

information on corrosion and its prevention through the provision of training courses, seminars, conferences, publications and other activities. The two most common causes of concrete corrosion are carbonation and chloride or 'salt attack'. The alkaline (high pH) conditions in concrete forms a passive film on the surface of the steel reinforcing bars, thus preventing or minimising corrosion. Reduction of the pH caused by “carbonation” or ingress of chloride (salt) causes the passive film to degrade, allowing the reinforcement to corrode in the presence of oxygen and moisture. As reinforcing bars rust, the volume of the rust products can PROACTIVE ASSET increase up to six times that of the original steel, thus increasing pressure on the MANAGEMENT surrounding material which slowly cracks the concrete. Over the course of many years, the cracks eventually appear on the surface and OF CONCRETE concrete starts to flake off or spall.

In addition to new materials being incorporated into the concrete mix, other additives have created 'self-compacting' and 'self-levelling' concrete which can save both time and money. Off-site construction of pre-stressed concrete panels, under factory conditions, permits a far greater degree of quality control. “Advances in admixtures means that we can build almost anything out of concrete these days,” Green said. “The Australian Standards for concrete work gives basic guidance for normal situations, but in aggressive environments such as tropical, coastal, acid-sulphate soils, etc., a structure will not necessarily achieve its design life if simply designed and constructed to comply with the Standards,” Cathodic protection is relatively simple research has been published through the said Green. in theory.
