Details
One of the key benefits of Blended Natural Sandstone paving is its resilience. Sandstone is a sedimentary rock known for its hardness and resistance to weathering, making it ideal for outdoor use. It can withstand the elements, including rain, frost, and sun, without losing its structural integrity or aesthetic appeal. Additionally, its naturally slip-resistant surface enhances safety, making it suitable for patios, walkways, and pool surrounds.
Moreover, Blended Natural Sandstone paving is environmentally friendly. It is sourced from natural quarries, and its production requires minimal processing compared to artificial paving materials. This not only reduces the carbon footprint but also ensures each paving slab has a unique, natural beauty that synthetic alternatives cannot replicate. In summary, Blended Natural Sandstone paving offers a blend of durability, safety, and ecological benefits, making it a superior choice for enhancing outdoor spaces.
Useful Information
Natural stone colour and maintenance
All natural stone products (Sandstone, Limestone and Granite) will have colour and texture variation to a greater or lesser extent within single pieces and from piece to piece. We recommend a reasonable amount of product is viewed at your local stockist before ordering. Natural stone products may contain minor imperfections. These will
depend on the characteristics of the product i.e. fossils, ferns, veining and quartz. Natural stone may develop added marking, deposits or patches as mineral content oxidises.
Product should be mixed from a number of packs prior to installation. Natural stone should always be laid on a full wet mortar bed.
A slurry primer (such as Bradbond) is recommended to be applied to the underside of all Natural Stone paving but is essential for Smooth Natural Sandstone, Natural Slate,
Riverwashed Limestone and Granite paving prior to laying to improve adhesion.
Sandstone
Sandstone needs to be handled very carefully when installing to minimise staining and we would advise that Smooth Natural Sandstone be sealed prior to laying using
a breathable sealer. However, if this is not possible, it should be covered up as it is installed and sealed as soon as it is laid.
The Silver Grey colour in all of our Natural stone products will vary with differing geological conditions. Such variations can lead to small particles of ironstone within the product creating a darkening of the surface with natural weathering.
Being pale in colouration, this natural weathering is more obvious with Silver Grey compared to other natural products in the Bradstone range.
Slurry Primer
The British Standard recommends that a slurry primer (should as Bradbond) should be applied to the underside of all paving prior to laying to improve adhesion
Differential Weathering
Differential weathering can cause patchy dark discolourations on the surface of individual units. Again this will generally diminish over time and will not affect long term
performance. This is due to differential weathering where the surface of the paving has cured at different rates. All decorative products will weather and change appearance
over time.
Efflorescence
Efflorescence can appear on all paving products as white patches or a lightening of the surface colour, but seems to disappear when wet.
It is formed by a normal chemical reaction which causes calcium hydroxide (lime) to migrate through the damp paving surface and then react with carbon dioxide in the atmosphere resulting in a deposit of calcium carbonate crystals. Efflorescence is very unpredictable in its occurrence and can happen at any time of the year but is more prevalent in winter.
Although there are cleaners available, efflorescence is a natural phenomenon and will generally disappear with the natural weathering process and the passage of time. It does not compromise the integrity of the paving. Aggregate Industries cannot accept responsibility for the effect of efflorescence which can be a characteristic of all good quality products with a high cement content.
