Exceptional Water Absorption Test Results: Stonelam Porcelain Slabs Lead the Industry

Stonelam is certified by Main Laboratory Sassuolo, meeting top global standards.

Stonelam (powered by Laminam) a leading name in the industry, presented its unglazed porcelain slab for water absorption tests. SASO has produced the standard SASO ISO 10545-3:2018 which provides tight controls over how the water absorption capacities of porcelain slabs are to be determined. Such rates impact the suitability of the different slabs, in particular, to be used in applications mostly facing moist exposure.

Exceptional results were achieved in the tests, and at 0.01%, the maximum water absorption registered for Stonelam slabs was only a fraction of the 0.5% standard. It demonstrates just how good products are, with advanced engineering, and they represent the best solution for applications demanding the highest strength requirements and resilience to environmental factors. submitted its unglazed porcelain slabs for water absorption testing as per the SASO ISO 10545-3:2018 standard. This sets strict rules for deciding the water absorption rates of porcelain slabs, which would directly determine their appropriateness for some applications, especially in moisture-exposed environments.

Water Absorption: A Crucial Factor in Performance

Water absorption plays a pivotal role in determining the longevity and performance of porcelain slabs. When porcelain slabs absorb water, they can expand and contract, especially when subjected to freezing and thawing cycles. This process can lead to cracks, weakening of the structure, and eventual failure of the slab. Slabs with high water absorption are also prone to staining, as liquids can easily penetrate the surface, resulting in discolouration

The SASO ISO 10545-3:2018 standard sets stringent limits on water absorption rates to ensure that porcelain slabs used in both interior and exterior applications, can withstand these challenges. Porcelain slabs are categorized as BIa under this standard, meaning they must exhibit water absorption levels below 0.5%. Stonelam’s test results far exceeded this requirement, with water absorption levels as low as 0.01%, highlighting their exceptional quality and performance.

One of the major benefits is the increased durability of the Stonelam slabs. In rainy or variable climatic conditions such as an outdoor facade, this resistance to water absorption ensures that they will not crack and, more importantly, degrade after years of freeze-thaw cycles or prolonged periods of rain.

Low absorption means that the Slabs do not absorb stains and dirt, which results in higher-absorbing porosity and can penetrate into the Slabs. The aesthetic appeal of Stonelam slabs is therefore sustained even in high-traffic or heavily used areas. This means it might be possible to put them outdoors where, subject to the most extreme conditions, they will retain their original appearance.

For instance, the low water absorption makes them prone to the growth of mould, mildew, and bacteria as these thrive well in moist environments. This makes them an excellent option for hygienic bathrooms, kitchens, and outdoor applications where moisture is present

How Stonelam Passed the Test

The testing process involved subjecting 50×50 cm samples of slabs to water immersion. The samples were prepared by cutting larger slabs, ensuring the test results accurately reflected the product’s real-world performance. After undergoing the prescribed drying and immersion steps, the slabs were evaluated for their water absorption capacity.

Conclusion

Stonelam’s porcelain slabs have proven their excellence by passing the water absorption test with remarkable results. With a water absorption rate far below the industry standard, these slabs offer superior performance and reliability, making them suitable for a wide range of applications. Whether used in moisture-prone areas or exposed to extreme weather, Stonelam ensures long-lasting durability, minimal maintenance, and enhanced resistance to environmental factors, setting a new benchmark for quality in the porcelain slabs industry.
