Setting the Standard for Quality and Confidence with over 12,000 tests on Portland Stone

At Albion Stone, we are proud of our long-standing commitment to excellence and innovation in the natural stone industry. For over 35 years, we have led the way in testing and quality assurance, ensuring that our Portland Stone consistently meets – and often exceeds – the most demanding industry standards.

Since 1988, we have worked closely with respected organisations such as the BRE and Sandbergs, sending samples of our stone for independent testing. Over this period, we have completed more than 12,000 individual tests, making Albion Stone’s Portland Stone one of the most extensively tested natural stones in the world.

This rigorous approach provides our customers with complete confidence in the durability, strength and performance of our stone, whether it’s being used in cladding, paving, restoration or new-build projects. We maintain a robust testing regime, with regular retesting carried out every 2 or 10 years, depending on the type of test and industry requirements. This ensures our data remains up to date and reflective of real-world performance.

The detailed test results we’ve built up over the years form the foundation of our CE Certificates, Declarations of Performance (DoP), and Technical Data Sheets. This depth of data enables designers and engineers to work with a lower factor of safety than would be required with other Portland Stones on the market, without compromising on quality or reliability.

Ultimately, our extensive testing programme helps us deliver a consistently high-quality product and supports the creation of buildings that stand the test of time. With Albion Stone, you’re not just choosing beautiful British stone – you’re choosing decades of proven performance and trusted expertise.
