The Waihi Beach shoreline has been the focus of erosion control since the 1950’s. During this time ad-hoc coastal erosion protection structures such as steel and timber retaining walls, gabion baskets, tipped rock and sand containers have been employed. Subsequent storm systems had a twofold effect on the coastal area, with both stormwater flow and the action of the sea taking a toll on creek outflows. The Surf Club is a public area and a popular stop-off for locals and visitors so providing a user-friendly solution was deemed important.
Good design is the first step towards the success of any civil engineering project, safe and efficient construction is the next.

In Orange, New South Wales, there was a requirement for long term vegetation control on the road edge next to a crash barrier.
The site was an ongoing maintenance problem in terms of erosion and vegetation control. Due to the proximity of the slope to the crash barriers and tight access corridor from the road, frequent maintenance was deemed dangerous for the Roads and Maritime Services (RMS) crew.
Fishing from the shoreline of Munna Point has been a favorite past time of the holiday makers using the Noosa River Holiday Park which since the 1920’s. Recently the water’s edge at Munna Point has experienced severe erosion to the point in which the council had to fence off this part of the beach to ensure public safety.
The risk of Geosynthetic Clay Liner (GCL) Bentonite erosion when installed beneath exposed Geomembranes has been a regular topic in the public domain over the past few years. Based on studies at the Queens University QUELTS site, the conclusion is that if traditional GCLs are installed below exposed Geomembranes, daily temperature variations create an environment that leads to downslope bentonite erosion and loss of GCL performance.
The QUELTS study described certain GCL types that provided resistance to erosion and ensuing public discussion has focused on these product parameters in isolation. It is worth a review with some updated findings, to ensure that any design process implemented to solve GCL bentonite erosion, does not compromise long term performance of the hydraulic barrier.
The City of Rockingham upgraded and extended Mundijong Road in 2013 to form Kulija road. More than $6 million in Federal funding was secured by the City of Rockingham to help build the 5 kilometre extension connecting the Kwinana Freeway, at the Baldivis Road exit, to Mandurah and Dixon roads.
This new road is a vital road corridor from the Kwinana Freeway to Rockingham’s city centre which will improve access to the region’s commercial and industrial areas.
Erosion problems started to occur soon after completion due to an uncontrolled flow from a piped outlet system that was washing sand and soils down an 80 m long slope of approximately 8.75% grade causing major channel erosion. More erosion was occurring on road side embankment slopes due to water runoff from the unkerbed road travelling down embankment slopes next to the road.
When it comes to stabilizing the subgrades that serve as the foundations for our pavements, cost, time, and lifespan are key considerations for the methods used by contractors. Chemical stabilization has recently become a popular choice among many contractors, but does this increase in popularity rest on misunderstandings about the cost savings and ease of use of this method? It’s time we debunk a few of the myths surrounding the benefits of chemical stabilization and examine how mechanical stabilization with geogrids might be a more effective solution. While geogrids may not always have the lowest initial cost compared to lime and cement stabilization, you may find this method makes the most sense in the long run.

In March 2010, Roma experienced its worst floods in over 100 years. Flooding also occurred in April 2011, a year of record rainfall in Roma. In early February 2012, Roma was devastated by its worst floods in history, eclipsing the level reached in 2010. There were 444 homes inundated, twice as many as were flooded in the two previous years. After three successive years of flooding, residents were unable to obtain insurance from some insurers unless action was taken to mitigate the flood risk in Roma. Previous flood mitigation was insufficient for the level of flooding being experienced.
Geofabrics was approached by Roadtek in Brisbane for some possible solutions regarding a problem at a site on Southern Cross Way, Brisbane. A stormwater drain had the issue of water being unable to drain away from the outlet.
Located in South Australia, this mine site had aggressive waste-water needing to be contained. For this application, a leakage of the lining system can cause damage and ultimately cause failure of the storage.
In a time-constrained environment, when faced with many requests for product approvals, the key question then becomes what parameters should a designer consider when asked to approve alternatives presented by contractors, particularly when contractors are trying to optimise the product purchase cost and keep construction costs down?
When culverts beneath a rail line are replaced, operators often struggle to construct a firm base for the culvert base to be founded especially when in majority of cases the subgrade materials are of inferior quality. Deep excavations and backfill are often required which is time consuming and could potentially prolong the closedown timeframe. The Presto GEOWEB® load support system will provide rail operators an economical and time saving solution by reducing both the excavation and backfill requirements.
Fouled or contaminated railway ballast is material recovered from the formation containing broken ballast particles, soil fines and other contaminants deposited during normal rail operations. The disposal of this material is an issue for many rail authorities as it may contain hazardous hyd
Much of the 40,000km of rail track traversing our great Australian land was constructed at a time when minimal engineering input was considered and therefore much of it is built upon low quality formations which over time has settled, deformed and lost much of its load bearing capacity.
Rail in NZ runs over a prepared subgrade with adequate subsoil drainage installed parallel to the line, this is then topped with a typical AP100mm broken face hard ballast rock.

The Saptashrungi gad is located in the East-West range of Shyadri mountains, approximately 65 km from Nashik. It is one of the most visited religious sites for pilgrims coming from neighbouring states like Karnataka, Andhra Pradesh, and Gujarat.
Australian Landfill Regulatory Guidelines place the world’s most stringent controls on geosynthetic clay liner (GCL) manufacturing and quality control from site. Recent specifications were written to build on the Geosynthetic Research Institute-GCL guidelines that were ideal for their time (achieving consensus alone is a remarkable result) but could simply not foresee the demands on GCL design that have arisen in the past decade. Recognizing this, regulatory bodies in the Australian landfill space engaged with key industry expertise to introduce performance requirements that reveal much more about GCLs than basic index testing standards, driven by modern demands in our challenging climate with complex leachates. This has resulted in GCL types in Australia that have different levels of quality when compared to products supplied in overseas markets.
In January of 2018 Concrete Canvas was used by Cowra Council in New South Wales to rectify a failed open drain following a substantial rainfall event. The heavy rainfall event led to undercutting and eventual failure of the existing corrugated steel drain.
The Yancoal Australia Hunter Valley Operations (HVO) is a multi-pit open-cut mine producing more than 13 million tonnes of thermal coal and semi-soft coking coal using dragline truck and shovel methodology.
Traditional theories suggest that water ingress into soils under a pavement will over wet the natural subgrade to its soaked CBR state and therefore induce heaving or create a softened support for the pavement.
In the case of SR27a and SR30, south of Kaikoura, there was very little space between the cliff face and the rail and road corridor, meaning a rockfall protection solution had to be able to provide sufficient protection with very little runoff area.
Kaikoura is a coastal town in the North Canterbury region of the South Island of New Zealand. It is a popular tourist destination known for its abundant wildlife and its year round sperm whale population. The region was badly affected by an earthquake in the November 2016. At the P1A site, the first of ten major slips north of Kaikoura, there was sufficient space to install a low maintenance landslide and rockfall protection solution in the form of a rockfilled face Green Terramesh Bund.
As part of this new residential development an overland flow path, stormwater basin and wetland area had to be protected against erosion as part of the development’s resource consents.
A gabion lined water course / wetland flow path was required for 1 in 100-year storm events for this new residential development. The channel is designed to cope with high water flow in heavy rain events hence the need for protection of the channels side walls using genuine Maccaferri gabion baskets.
The design and build of a Modular Rockfall Protection Wall (MRPW) for the Kaikoura Earthquake Response project was a team effort driven by the North Canterbury Transport Infrastructure Recovery (NCTIR); including Fulton Hogan, Stahlton Engineered Concrete and Geofabrics.
The region was badly affected by an earthquake on November 2016. The magnitude 7.8(Mw) earthquake caused landslides and rockfall along the coastal road of State Highway, SH1. The state highway links the town north of Kaikoura to Blenheim and south to Christchurch and at the same time serves as a major tourist route with its scenic view along the coast. Rail corridor also sits along the side of the SH1 responsible as a major transportation mode to bring goods in from Picton.
QR and Civil Engineers throughout the country face difficult engineering problems daily, but when they can partner with trusted experts in geosynthetics, solutions which were not possible 20 years ago can now be realised.
Worldwide, it is estimated that there are an average of two tailings dam failures every year[i]. In Australia, the regulatory environment has made it extremely difficult to build a new dam. These are indications that current practice is not working to the level required. Not only can tailings storage work better, but it can also be done economically.
The new 11 storey Ei8ht Apartment building on South Esplanade on the Glenelg Foreshore created a unique engineering problem for the project team.
During the past 20 years there has been a great deal of interest in obsoleting the use of welded wire mesh for underground secondary roof support applications.
Welded wire mesh has inherent issues with material handling, related to unusable material loss, personal injuries and installed longevity. Mines report that for every ten welded wire panels transported underground, one cannot be installed. Injuries associated with welded wire mesh installation range from shoulder and back sprains to hand and facial punctures.

In April 2017 a consultant enquired about the use of a GCCM (Geosynthetic Cementitious Composite mat) in rehabilitating an eroding drainage channel for a local government authority, which they thought would be an economical solution to their problem. The channel was to be 3.2 m wide crest to crest and 100 m long. The objective was for the channel to be installed up stream of a new guardrail installation and to protect the new guardrail footings from being scoured in the event of a heavy rainfall event.

WT Partnership’s report, Track Formation Rehabilitation Options (Geofabrics) – Cost Options and Whole of Life Comparisons (June 2016), was carried out comparing a range of different scenarios using Geosynthetics and comparing them to conventional track formation practices which do not utilise Geosynthetic solutions.
The study investigated a 200 metre long section of track renewal over a 40 year life span and made conservative assumptions around total replacement costs. The study investigated three capital works life span replacement intervals: 15, 20 and 25 years. These intervals can be considered conservative as geosynthetics have proven to contribute to the performance of rail lines for intervals in excess of these time frames.
This suburban NSW Wastewater Treatment Plant has a capacity of up to 18 mega Litres per day servicing up to approximately 75,000 people. For normal operations, the plant makes use of 2 belt filter presses to dewater biosolids to 14-17 percent solids. The biosolids are removed by truck daily to be sent to land crops and sugar cane farms.
In April 2015, Concrete Canvas GCCM was used to line a ditch next to the new Bexhill to Hastings link road.
South Australia Cricket Association (SACA) and Adelaide City Council recently collaborated on the redevelopment of Narnungga (Park 25) which will include a new multi-purpose sports pavilion to replace the existing sporting clubhouses, improved cricket and football fields and a floodlit beach sports facility.
One of the biggest issues historically with the football/cricket field had been its undulating surface and poor drainage. This was in part due to the clay type soils typical of this region coupled with poor natural drainage. Therefore one of the most important aspects of the project was ensuring that the drainage was significantly improved to ensure excellent ongoing playing conditions during the wet and dry season for both SACA and the local South Australian Amateur Football league.
