As this product is heavier than we can deliver on our standard tail-lift service we have two options for delivery:

- if you have your own offloading equipment on site, for example a fork-lift or tele handler (not simply manpower alone), you can benefit from our lower price by agreeing to use your own offloading equipment to remove the goods from the vehicle

- if you do not have your own offloading equipment, we can split the packs across extra pallets for you and offload as usual on our tail-lift and pump truck

Please ensure you agree to the appropriate option

Global Stone's natural riven sandstone has handcut edges and a naturally uneven surface. Castle grey comes in light to mid grey shades of sandstone with occasional buff

Note, this paving is shown with an insert of Modak Rose to add a contrasting shade

Colour Variation
Moderately Varied

This paving has a moderate amount of colour and shading variation present within the range

Water Absorbency
Low Absorption

During tests, this paving absorbs less than 1.2% water when fully saturated. The lower the water absorption, the lower the risk of algae growth and staining. By comparison, concrete paving has an average water absorption of 6%

Flexural Strength

During testing, this paving showed flexural strength of 22.3 Mpa. The flexural strength value shows how much bending stress a paving unit can be put under before it breaks and the higher the number, the stronger the paving. By comparison, concrete paving has an average flexural strangth of 5 Mpa

Frost Resistance

During a repeated test cycle of freezing to -40 degrees Fahrenheit, followed by thawing, this paving only lost 0.2 Mpa of flexural strength. This result demonstrates excellent paving resilience

Slip Resistance
Low Risk

This paving has a slip resistance PTV rating of 56 when wet. A pendulum is used to swing across the stone to determine friction. The rougher the surface, the more the pendulum slows and the higher the value

There are many types of natural stone available, so it is important to choose the right natural stone for you.

All products from Global Stone are CE marked to ensure they meet with strict EU regulations that were introduced in 2013. European standards EN1341 (flagstones), EN1342 (pavers) and EN1343 (kerbs) specify the requirements and test methods for each of these. The CE testing covers areas including water absorbency, flexural strength and freeze/thaw resistance.

All natural stone products have been tested to show the various properties of each stone and how it is likely to react under different circumstances.

Material Information

Natural Stone Characteristics:

All natural stone products are unique and will vary in colour and texture, often showing distinctive markings, minor imperfections and may include mineral deposits such as iron and quartzite. Sizes are nominal and may vary. Some paving manufacturers include the pointing allowance in the individual slab sizes whereas others include the pointing allowance in the overall pack coverage. The product images shown are as accurate as photographic processes allow and may appear differently in accordance with lighting conditions and screen calibration in addition to the natural variation occurring between batches. Images may not be a true representation of a particular product size, use or laying pattern. Descriptions provided offer a combination of the manufacturer's and our own opinion of the product's characteristics and features.

Sandstone Description:

Sandstone is a type of sedimentary rock formed of gritty sand grains and is available in a variety of colours. Sandstone paving is available in a range of different textures, often relying on secondary processing to achieve these finishes.

- Variable Thickness Riven Sandstone This type of sandstone has a natural cleft, uneven surface texture with occasional ridges and the edges of the slabs are usually tapered with the larger face of the slab to be laid uppermost. Variable thickness stone, i.e. those marked with a depth range such as 15-22mm +/- (refer to the Unit Depth description) have a wider variation in thickness than a calibrated thickness stone. When laid on a full mortar bed, this enables any variation in thickness to be adjusted within the bed.

- Calibrated Riven Sandstone Many riven sandstone products are offered at a 'calibrated' thickness which means the paving has been cut to a less variable, relatively even depth, usually around 22mm +/-, to make it easier to lay. The +/- indictaes a minor tolerance on the dimensions in accordance with British Standards. This paving should still be laid on a full mortar bed.

Sandstone Colours:

Sandstone is available in a wide range of colours, some subtle and some vivid. The ranges comprise of a selection of core colours combined with subtle contrasting shades, and the balance of shades can vary between batches of even the same stone due to different seams in the stone quarry occurring over time. The blend of colours may include grey, pink, khaki, maroon, buff and many more shades which when combined, create the mix of colours associated with the colour name of the paving. The colour intensity increases when the paving is wet. Most brands offer the same range of colours with slightly different names. If colour variation is not a desirable feature, then it is recommeneded that natural stone and especially sandstone should not be considered as a paving choice. BE AWARE that not ALL sandstone is the same quality - some unknown brands may not have been tested for suitability in the UK climate and may crack during cold weather.
