Gosford Quarries Civil Sandstone For Creeks, Rivers, Waterways And Filtration Material Supply
Australian Sandstone is the ideal retaining and filtration material due to its natural durability, porosity, breathability, non-polluting nature and versatility. Gosford Quarries supply councils, civil contractors, foreshore and water authorities with natural virgin sandstone materials such as boulders, armour rock, rip-rap, gabion and logs for erosion prevention under severe weather conditions.
Sydney Harbour Foreshore Authorities and Rainwater river catchments authorities prioritise VENM sandstone materials as they are natural and do not pollute rivers and affect fish and wildlife. Other materials such as concrete and granite can affect the marine environment and certain breeds of fish and wildlife and can also contaminate freshwater habitats.
The use of natural sandstone boulders creates pockets for fish and habitats for them to breed and these safe havens encourage fish breeding and other wildlife habitats in a more natural ecosystem.
“Sandstone walls are often cheaper than concrete structures and are beneficial to the natural habitat encouraging and supporting the natural ecosystems of rivers, creeks, lakes and coastlines.”
Civil Sandstone For Creeks, Rivers, Estuaries, Waterways And Seawalls
Gosford Quarries have a wide range of highly sought after raw quarry civil material for Civil Projects involving all environment projects involving filtration and soil retention management for waterways.
Our flat sandstone boulders function as a perfect embankment retention rock. We have rock revetment for both freshwater (rock battery for creek beds) and saltwater (Marine) civil projects.

“Our sandstone embankments rocks consist of sandstone boulders which are also used in blade walling and sandstone rock armoury for embankment stabilisation.”
Sandstone Boulders And Random Rock For Civil Design
Gosford Quarries supply Rock Armour for rivers and creeks at 500mm to 1 metre is ideal for creek and river banks.
Flatter random rocks can be stacked and designed to lock into one another. These are usually in basic diamond shapes and are quarried by design to lock and protect embankments and act as erosion controls.
Some Civil Engineers will specify smaller material sizes of the above for specific Civil Projects. The Hawkesbury management involved 500mm to 1-metre random rock with 300-500m sandstone balls in design, for example.
Sandstone Logs and Sandstone Rock armoury have been used in the Parramatta River Civil Project.
What Is A Sandstone Rock Armoury?
Gosford Quarries Sandstone Boulder Walls Landscape Random Rock Retaining Civil Product
Sandstone Riprap or sandstone rock armour as it is both known by if the use of sandstone civil product (usually large boulders, large sandstone rocks, revetment rocks, etc), to protect coastlines and any man-made structure subject to erosion by water of any volume, velocity and force from streams, rivers or the sea (wave incursion, etc).
When used as seawalls, these large, incredibly heavy sandstone boulders, locking together by design and specific placement in civil engineering, control erosion to provide ‘armour’ as in protection (hence the origin of the name and terminology).
Sandstone Rock Armour is supplied in both ballast and gabion sandstone products to Civil Industry. Rock Armour is a by-product of our dimensional stone extraction, so the quality is in the same region of the dimensional stone we also supply, obviously the dimensional stone being the higher-grade product. This difference is highlighted in how the sandstone is ripped up in boulders and then screened to size to meet RMS, MPA, EPA standards.
Because Gosford Quarries always target a high-quality area of our quarry to ensure civil product quality at the extraction point, rock armour, produced from a retargeting of this area of extraction after an initial larger extraction, has the commensurate innate quality due to the location it is lifted from.
What Is Sandstone Rock Revetment?
Sandstone Rock Revetment is the use of large sandstone boulders in Civil Design to create a bastion of ‘seawall’ to absorb the shock and bombardment of incoming waves and seawater to coastlines, etc
Rocks Revetement are installed in a tiered, sloping manner and comprise of various large sandstone rock sizes the civil engineer and with which a civil engineer uses their knowledge of physics and engineering to prevent erosion, loss of shoreline and wave intrusion.

Due to its MPA rating of hardness and durability, and the long-lasting nature of hard sedimentary rock such as sandstone, revetment walling provides tough and powerful long-lasting protection of any marine shoreline, coastline, bay, etc.
Gosford Quarries Sandstone Revetment Rock is a higher grade sandstone accounting for 30-40% of all quarried materials meeting MPA and Council standards. When it comes to extraction, it is not so much about the shape of the sandstone we are extracting, but in our minds the quality and MPA specifications we want to achieve in making civil sandstone products available for supply to our civil contracting clients.
Sandstone Seawalls in Civil Marine Projects

Like their waterway counterparts, marine seawalls and rock armour not only dissipate wave energy crashing upon coastline boundaries but being sandstone in origin, aesthetically blend to the environmental surrounds visually pleasing to the eye. Sandstone, of course, as a 100% Australian natural stone product, is ‘natural looking’ by nature. These seawalls can be focal points and “heroes” by civil design as much as blended and ‘integrated’ against landscapes and seascapes.
Sandstone Bulkheads in Civil Engineering For Marine Applications
Sandstone bulkheads are usually installed around major piping and waterways, having the same characteristics as all other filtration rocks and seawall barriers and revetment rock, are pH neutral and friendly to the environment also.
“Sandstone Bulkheads are supplied in two forms from Gosford Quarries; sandstone logs and dimensional (large) stone at medium to large scale (sandstone boulders and large sandstone rocks).”

“Gosford Quarries also supply ‘bobcat rock’ (civil layman’s term) weighted and dimension rock that can be picked up by a little digger such as a bobcat.”
These sandstone boulders are stacked to create the bulkhead, are diamond-shaped, flat or round and as specified by the civil designer of each unique civil marine project. The bulkhead in its construction does require large dimension rock that can ‘interlock’ and hence by weight, structure and durability perform a function to weather the onslaught of water and wave incursion at length.
Sandstone Random Rock For Civil Design
Sandstone Random Rock is extracted from the quarry in roundish shapes, resulting from the way the sandstone is ripped out from the quarry site. These are usually 1 metre to 1.5 metres dimension stone, flat and used for stack walls.
When considering the recent terrible floods throughout the NSW and QLD regions, 500mm to 1-metre random rocks and greater in dimension are needed for when the amount of water flowing rises quickly and hence the strength of the flow becomes significantly increased.
Hence flood zones need large boulders that cannot be washed away or roll over or roll onwards causing potential blocks of the watercourse or an unwanted redirection through random movement, etc.
Blade Walling, Random Walling, Random Shaped Walling For Civil Projects With Creeks, Rivers, Watercourses And Waterways
Our sandstone blade walling can be cut to dimension, specified by Civil Engineers, used in creek applications, etc. Sandstone logs are also another option for creek beds and can also be installed to slow the watercourse.
Stackable sandstone random quarry rock and rounded sandstone boulders can both be used to build civil retaining walls and to slow water from creeks and are deployed in a wide range of civil uses according to Civil Design.
Filtration, Runoff, Soil Retention and Course Slowing for Waterways
Sandstone boulders help to retain soil with rainwater runoff concerns.
Our random rock sandstone gabions are used in gabion baskets for retaining walls and decorative edges, also decorative in function, and as a filtration mechanism to filter water behind walls (often used in cemeteries and other instances).

A more natural-looking barrier, the pH neutral, alkaline nature of sandstone is also incredibly kind and exciting to creatures like our little friends the frogs. Any wildlife living amongst moisture environments (amphibians, etc) love sandstone when used for creek linings and silt barriers. They also love it because it is a safe environment for them to exist in, also giving them a natural protective barrier as well they can hide and populate around and within.
Gosford Quarries Sandstone Gabion Product
“Gosford Quarries 75mm to 150mm sandstone spalls are available for gabion cages for retaining walls, both decorative and functional. We have different sizes in 40mm-80mm and 50-90mm usually used to retain walls as well.”
Gabions can also be used for entries to stormwater pipes, to filter and stop rubbish penetration to waterways, catching bottles, etc. Stormwater aprons (also known as rip rap aprons), gabion cages and gabion mats can also be installed. Gabion Matts lay flat and gabion cages stacked upon them. Rivers and creek canals using feature gabion installations as part of revampment work in civil design projects.
Rip Rap is a terminology that is basically similar to the definition and specification of gabion rock, however, Rip Rap may be specified and called thus due to specifications in size. Rip Rap Aprons are angle faced or angled embankment rocks or amour. Rip Rap rock keeps slopes and inclines stable and rip rap also stops erosion.
General stormwater drainage is also another function of gabion with sediment control stopping runoff and as a barrier before the water reaches creeks, rivers and, eventually, the ocean.
When considering marine sea walls, Dee Why for example, where splash and wave zones are formidable you need large sandstone boulders.
Sandstone As A Filtration Material
“Sandstone civil material is an excellent filtration material, helping to filtrate water and purifying the water in the process as the water passes through its sediments. Sandstone is mostly pH neutral and water filtering through it usually results in the same pH levels. Water passing through a medium, where it splashes has a greater introduction of ‘air’, produces more oxygen acting as another purification process. Sandstone also acts to remove and catch (and reduce) sediment. ”
Gosford Quarries supplied approximately 1000 tonne of sandstone civil materials in the civil erosion prevention project at Colloray.
At Bankstown Airport, sandstone was used as a treatment rock for the big canal waterway, catching stormwater from factories and any potential contaminants and materials from entering the canal.
