1 INTRODUCTION

As requested, Regional Geotechnical Solutions Pty Ltd (RGS) has undertaken a geotechnical

assessment of the indurated sand profile to the south of Lake Cathie.

The coastline around Lake Cathie is subject to a high energy wave climate and in some areas

(particularly Illaroo Road) coastal processes threaten foreshore assets and recreational amenity

along the coastal precinct. Erosion has occurred south of the Lake Cathie entrance and has led to

exposure of indurated sands, locally referred to as coffee rock, that underlie the dunal system.

Coastal erosion is likely to increase with time given current scenarios for climate change and the

projected rise in ocean levels.

Several coastal hazard studies have been undertaken on the subject section of coastline and it

was recommended that a geotechnical investigation of the indurated sand (coffee rock) horizon

be undertaken. The objective of the investigation was to determine the geological characteristics

of the indurated sand profile at eight nominated sites to the south of Lake Cathie so that it can be

included in future coastal erosion recession studies.

The purpose of the work described herein was to provide the following:

The factual data obtained from the field and laboratory testing including a summary of the

extent of indurated sand profiles present and the properties of the indurated sand profiles;

A cross section showing the interpreted geological profile for each site.

The work was commissioned by Port Macquarie Hastings Council.

2 FIELD WORK

Field work for the assessment was undertaken in September 2013 and included:

Observation of site features and surrounding features relevant to the geotechnical

conditions of the site;

Twenty six boreholes undertaken by a track mounted drilling rig equipped with solid flyte

augers, logged and sampled at the locations nominated by Council. Wash boring

techniques were utilised below the water table where required and SPT testing was

undertaken at regular intervals in each borehole;

Rock coring was undertaken at nine of the borehole locations to recover the indurated

sand profile. To ensure maximum core recovery, drilling penetration rates during coring

were reduced, drilling muds were added to the return waters and a core barrel of 1m

length was used. Two cored boreholes were attempted using handheld pro-line equipment;

Fifteen boreholes were undertaken by hand auger on the upper beach profile where

vehicle access was restricted;

Rock coring using a portable hydraulic power unit with a 60mm steel dyna-tube

attachment was used near one location (BH32) to recover additional indurated sand

material from an exposed profile for testing;

Engineering logs of the boreholes are presented in Appendix A. The locations of the boreholes are

shown on Figure 1-1 to 1-7. Borehole locations were pegged and subsequently picked up by

detailed survey. A summary sheet of the borehole positions is provided in Appendix A. Reduced

levels at the borehole locations are shown on the logs.

3 BACKGROUND – INDURATED SAND

Indurated sand, or coffee rock as it is locally known, occurs within unconsolidated sand deposits as

brown to dark brown cemented layers of variable thickness and strength. The formation of the

indurated sand layers is typically understood to occur via the leaching of aluminium, iron, clay fines

and organic compounds from the topsoil horizon which are then precipitated out in the lower

profile above the water table as a cement, binding the sand grains and forming layers of lower

permeability. The formation of indurated sand layers is described in detail by Brooke et al (2008),

“Development, composition and age of indurated sand layers in the Late Quaternary coastal

deposits of Northern Moreton Bay, Queensland”.

Previous experience on the North Coast with indurated sand profiles in coastal sand dunes and

sand plains has revealed significant variation in their vertical and horizontal extent and variable

strength properties. The extent of the indurated sand horizons in the subsurface profile is associated

with local topography and geological environments at the time of deposition. Changes in

geological settings over time and recent anthropological modifications to the natural surface

profiles can make it difficult to interpret the potential presence or extent of indurated sand horizons.

The generally impermeable nature of the indurated sand horizons also results in the development of

shallow or multiple perched water tables, and subsequently are important hydrological controls

where they are present.

4 LABORATORY TESTING

Testing was designed to assess potential strength of the indurated sand material and its potential

break down due to environmental conditions that exposed material would be exposed to

including wind, wave and water erosion.

Samples retrieved during field work for the current geotechnical assessment were returned to NATA

registered laboratories for testing which included the following:

Slake Durability (AS4133.3.4) on selected bulk core samples. Determines the resistance

offered by a rock sample to weakening and disintegration when subjected to two standard

cycles of drying and wetting and physical abrasion in a controlled chemical environment;

Weak Particle (AS1141.32) - including clay lumps, soft and friable particles on selected bulk

core samples. The percentage of weak particles in a bulk coarse aggregate sample is

determined by breaking up coarse particles using finger pressure;

Direct Shear testing (AS1289 6.2.2) on selected core samples to determine peak and

residual shear strengths;


RGS20202.1-AC

13 January 2014

Indirect Tensile Strength – Brazilian (Test Method QMRD Q185) on selected core samples;

Point load strength index testing (Test Method RTA 223) on selected core samples. Testing

was undertaken on samples at natural moisture content and on selected samples dried

back in a low temperature oven (50°C);

Uniaxial Compressive Strength (UCS) testing (AS4133.4.2.1) on selected core samples;

Sodium Sulphate Soundness Test (Test Method AS 1141.24) on selected bulk core samples

This method determines the loss of mass due to disintegration when exposed to sodium

sulfate solutions over repeated cycles of wetting and drying;

Moisture Content (AS 1289 2.1.1);

Particle Size Distribution (AS 1289 3.6.1) on selected non-cemented samples and on samples

of broken up indurated sands, prior to and then post artificial weathering treatment;

Pre-treatment of aggregates with artificial weathering (Test Method RTA T103). This method

simulates the breakdown of potentially unstable material under environmental and service

conditions by subjecting the material to cyclic wetting and drying.

5 SITE CONDITIONS

5.1 Surface conditions

Lake Cathie is a coastal village located approximately 10km south of Port Macquarie. The section

of Lighthouse Beach where the investigation was undertaken is approximately 1.8km long and is

situated between the Lake Cathie ocean entrance and Middle Rock, a large flat rock outcrop

present on the beach.

An image of the site taken from the NSW Department of Property information website is

reproduced below.

Area of investigation situated between the Lake Cathie ocean entrance

and Middle Rock.


RGS20202.1-AC

13 January 2014

The topography of the site has been described in the Lake Cathie Coastal Hazard Study (SMEC,

2010). Key features of the site as described in that report include:

Much of the beach is flanked by urban development;

To the south of Illaroo Drive a narrow coastal reserve is present between the urban

development and coastline;

Coastal erosion has exposed the underlying indurated sand layer (coffee rock). This erosion

is most pronounced in the area adjacent to Illaroo Road;

Foredune/ embankment levels at Lake Cathie are about 8 m above AHD at the southern

end of Illaroo Road and around 7.5 m AHD at the northern end;

Indurated sands (coffee rock) outcrop along the beach.

Site observations and supplied survey information indicate the upper beach berm typically grades

up from the surf zone to the fore dune at angles of approximately 5 to 10°. Outcrops of moderately

weathered dolerite of estimated high strength were observed at two locations within the inshore

swash zone as shown the attached Figure 1. Near flat layers of indurated sand layers outcrop onto

the upper beach berm at several locations as shown in Figure 1. The surface of these indurated

sand horizons are typically uneven and contained rounded depressions and holes where sands

and gravels had accumulated. Ground water discharge from the toe of the foredune onto the

indurated sand platforms was observed.

Site D- Wet zone at toe of foredune where

groundwater is discharging and pooling on top

of the indurated sand platform.

Moderately Weathered Dolerite outcropping in

swash zone in vicinity of Site A.

The eroded foredune scarp above the upper beach berm ranges in height from approximately 3m

in the north to 5.5m in the south and typically has an overall slope at approximately 25 to 45°.

Where indurated sand horizon(s) are exposed in the fore dune they have near vertical scarps of 1

to 2m height. Weak, pale orange iron or carbonate cementing was observed in the sand profile,

above the dark brown indurated sand horizon in the vicinity of Site F. The upper scarp profile is

typically over steep (30 to 50°) where the profile is partly stabilised by exposed roots.


RGS20202.1-AC

13 January 2014

Behind the eroded scarp there are remnant dune crests with elevations of up to 9m AHD present in

the south. To the north, particularly in the vicinity of Illaroo Drive the dune crests appear to have

either been eroded away, or been removed by earthworks. Behind the foredune there is a coastal

sand plain that is near level for approximately 50 to 100m west of the dune before grading up a

residual ridge line that is orientated to the north east and is up to 20m AHD in height.

Site B – Flat terrain behind foredune scarp.

Illaroo Drive situated ~20m behind scarp.

Site F – Steep scarp with weak iron cementing

above dark brown indurated sand horizon.

5.2 Subsurface Conditions

Reference to the 1:25,000 Port Macquarie Quaternary Geology Map indicates the sites are situated

in an area of Pleistocene dunes that comprises aeolian and marine sands. Published mapping of

the area by the NSW Geological Survey (Quarterly Notes, October 2007) indicates that the

outcropping rock at Middle Rock Point is the Karikeree Metadolerite.

The boreholes encountered a variable soil profile as summarised in Tables 1, 2A, 2B, 2C and 2D.

Groundwater was encountered at the levels shown in Table 2. It should be noted that fluctuations

in groundwater levels can occur as a result of seasonal variations, temperature, rainfall and other

similar factors, the influence of which may not have been apparent at the time of the assessment.

6 DISCUSSION

6.1 General

The results of the investigation indicate a generally consistent profile is present comprising aeolian

sand deposits that include a broad zone of indurated sands that have formed insitu, overlaying

and sometimes incorporating marine sand and gravel deposits that in turn overlay residual clays or

weathered dolerite. The residual profile sloped gently to the east and was typically encountered

between -0.5 to 2m AHD. The inferred geological profiles at the eight sites are presented in Figures

2A to 2H.

The broad zones of indurated sand deposits were relatively complex and included grey and brown

stained sands that were non-cemented and discrete lenses of cemented indurated sand that had

variable horizontal and vertical distribution. The degree of cementing within the indurated sand

lenses was also variable with point load index strength test results on cemented materials ranging

from extremely low to medium.

Indurated sand lenses are formed by cementation above fluctuating water tables and the degree

of cementing is controlled by a range of factors including extent and properties of overlying topsoil

layers, water table fluctuation, sand properties, groundwater chemistry and other variables. The

position of the water table within the coastal sand dune profile varies in relation to surface

topography and presence of older underlying low permeability indurated sand or residual soil

profiles. The vertical and horizontal distributions of the indurated sand lenses can subsequently be

very complex. A conceptual model of indurated sand formation in an ancient coastal geological

setting is produced in Plate 1 which illustrates the potentially variable distribution of the indurated

sand lenses. Subsequent coastal erosion processes have further shaped the profile to what is

currently exposed.

Localised thin indurated sand layers encountered in the investigation such as in BH16 and BH17 at

Site F are likely to be associated with the presence of shallow lagoons or swales that have formed

behind the dune system.

Plate 1: Conceptual model of possible indurated sand formation and subsequent coastal

erosion that has resulted in the inferred profile encountered at Site B.

6.2 Laboratory Testing

Test results are presented in Appendix B and a brief discussion of test results are outlined below:

6.2.1 Strength Testing

Point load strength index testing of selected indurated sand samples revealed indicative strengths

ranging from extremely low to medium. Testing on Highly Weathered Dolerite from BH22 (6.0m)

revealed it was of medium strength.

There is speculation that dried samples of indurated sand have a higher strength than wet samples.

Subsequently point load testing was undertaken on indurated sand core samples at natural

moisture content and for comparison samples of immediately adjacent core samples were dried

back in a low temperature oven (50°C) for 48 hours prior to point load testing. It is noted that

cementing within the indurated sand profile is extremely variable and adjacent samples of core

may not have the same degree of cementing, however, the results indicated the dried samples

had significantly lower strength than the samples at natural moisture content as presented in Graph


RGS20202.1-AC

13 January 2014

1. This suggests that the drying / heating process in the low temperature oven has broken down the

cement material present in the indurated sand.

Graph 1

The speculation that the dried indurated sand has a higher strength than the in-situ material may

have been based on observation of exposed indurated sand profiles in the eroded scarps. Point

load testing on samples of exposed indurated sand material from BH32 and selected hand

specimens indicated the exposed materials did not have higher strengths than the samples

collected from the cored boreholes, however, observations of the cementing in the exposed

profiles suggested that the cementing was more continuous compared to profiles observed in the

boreholes behind the scarp. For example at Site B, the indurated sand horizon that is exposed in the

eroded scarp is approximately 2m thick, while the cored borehole (BH26) located approximately

five metres behind the scarp encountered a zone of stained sands with only thin indurated sand

lenses present at the same elevation.

The indurated sand exposures are subject to a range of weathering processes that include

accumulation of marine salts and repeated wetting and drying cycles. In addition groundwater

that is being discharged above the low permeability indurated sand horizons may contain

compounds that oxidise or precipitate upon exposure to the atmosphere. The combination of

these processes occurring where the indurated sand horizons outcrop in the scarps may be

resulting in additional cementing occurring adjacent to the original indurated sand horizon.

Site B – Thick indurated sand horizon in exposed scarp. BH26 located

behind scarp encountered only a zone of stained sand with thin

indurated sand lenses at similar elevation.

Uniaxial Compressive Strength testing on selected samples revealed the following:

BH5 (4.50 – 4.65m) UCS = 3.13MPa. Point load index testing on adjacent core sample from

4.70m had an index of 0.22Mpa. This results in a correlation factor of approximately 14.

BH32 (0.30 – 0.48m) UCS = 1.67MPa. Point load index testing on adjacent core sample from

4.70m had an index of 0.28Mpa. This results in a correlation factor of approximately 6.

Direct shear testing on a selected sample of indurated sample from BH2 revealed a peak angle of

friction of 56.7° and cohesion of 152.6kPa.

Brazilian strength testing on a sample of indurated sand core from BH32 revealed an indirect tensile

strength of 0.27Mpa.

6.2.2 Weathering

To assess potential breakdown of material due to weathering, sticks of indurated sand core from

BH13 were cut into fragments and the particle size distribution determined. The sample was then

subject to artificial weathering (RMS-T103) which simulates the breakdown of potentially unstable

material under environmental and service conditions by immersing the sample in water, allowing

standing for 16 hours and then drying the sample on a hot plate. When the water is evaporated the


RGS20202.1-AC

13 January 2014

process is repeated ten times. During testing the sample broke up to its constituent sand particles

after only three cycles of pre-treatment.

An alternative test to the artificial weathering is the slake durability index test. Sticks of indurated

sand core from BH32 were cut into ten nominal 50mm lengths and the fragments were placed in a

cylindrical drum fabricated from 2mm sieve cloth. The sample is dried before water is placed in the

drum which is rotated at 20r/min for 10 minutes before the sample is dried again and the retained

mass calculated. After one cycle there was only 4.5% of the material remaining and high

deterioration of the sample was observed. After the second cycle all of the indurated sand

samples had broken down to their constituent sand particles.

Mechanical pre-treatment (Test Method RMS-T102) and Los Angeles Abrasion testing was proposed

on selected samples however the samples collected were not of sufficient strength for such testing

and it was not undertaken.

Sodium Sulphate Soundness testing (Test Method AS 1141.24) was undertaken on core samples from

BH32 that were cut into nominal 50mm lengths. This method determines the loss of mass due to

disintegration when exposed to sodium sulfate solution over repeated cycles of wetting and drying.

Similarly to the other weathering testing the indurated sand fragments broke down to their

constituent sand particles during the wetting and drying cycles.

Weak Particle testing (Test Method AS1141.32) was undertaken on core samples from BH32 that

were cut into nominal 50mm lengths. This method determines the percentage of weak particles in

coarse aggregates which are determined using finger pressure. 92% of the indurated sand particles

were found to be weak.

In summary, the results of the weathering tests indicated that the indurated sand material broke

down rapidly upon artificial weathering and it is difficult to quantify the weathering properties using

standard aggregate or rock testing methods.

7 LIMITATIONS

The findings presented in the report and used as the basis for recommendations presented herein

were obtained using normal, industry accepted geotechnical design practises and standards. To
