SALT-TOLERANT SANDSTONE SUPPLY FOR CIVIL PROJECTS
Gosford Quarries’ salt-tolerant sandstone range is tested extensively to weather constant saltwater immersion (seawater locations such as estuaries, bays, harbours and coastlines).
Large Civil Project – Land & Marine Group – Jamison Town Job – Tench Reserve & Boat Ramp (Marine and Civil)
As a matter of proper business practice, Gosford Quarries also undertakes regular Physical Testing for all of our types of sandstone under the American Standard Testing Methods and by NATA registered Laboratories.
Our salt-tolerant sandstone adheres to Australian Standards, which the Designers Corporation of Australian Standards Committee and ISOs designate.
Not all sandstone is salt-tolerant or suitable for use in saline environments. All-natural materials (not only natural sandstone) will be impacted by saltwater erosion over time.
It is essential to speak to one of our sandstone experts regarding the application of sandstone in saltwater environments and sealers and installation methods recommended for use in those projects.
Gosford Quarries has sandstone materials that meet salt-tolerant sandstone criteria; contact us at (02) 8585 8282 for more information.

- Gosford Quarries source their raw and crushed civil sandstone materials from a single, exclusive quarry location when fulfilling orders for the scope of works at any scale.
- Gosford Quarries has 6 exclusive quarries that extract a variety of sandstone products. Extracting the stone from exclusive quarries means that the quality of the material is consistently tested for quality and reliability by government and RMS specifications and requirements.
- Civil sandstone products quarried from one exclusive location will have slight variances as they were sourced from a common vein and location. Other suppliers extract material from untested and inconsistent sites, making it impossible to ensure the quality and reliability of their products.
- Natural quarry sites are the preferred source of civil sandstone by Councils, government organisations, and Sandstone council landscaping projects because we can continually test and compare results with historical sandstone data.
ARE GOSFORD QUARRIES’ CIVIL SANDSTONE MATERIALS AND CIVIL SANDSTONE PRODUCTS IMPORTED?
Gosford Quarries Sandstone is 100% Natural Australian Sandstone!
When sandstone is imported, the origin of the sandstone products supplied and, hence, their overall integrity and quality when used in a civil construction project cannot be determined.

“Even in local Australian supply lines, many different sandstone supply companies may quarry raw civil sandstone materials from various areas, i.e., quarries, commercial sites and demolition sites, which means different grades of supply ranging between dry, hard and soft sandstone, there will therefore be no consistency in quality, and there will be huge variances across the entire project supply.
