These bullnose units from Global Stone are a versatile feature ideally suited to steps, water feature framing and as a coping stone to complete a walling project. The bullnose finish sections are made from sawn sandstone with a fine textured finish as offered in the Serenity paving collection and each pack contains 35 units. Mint comes in light buff shades with beige and occasional pink undertones
This paving has a high amount of colour and shading variation present within the range
During tests, this paving absorbs less than 2.82% 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%
During testing, this paving showed flexural strength of 15.3 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
During a repeated test cycle of freezing to -40 degrees Fahrenheit, followed by thawing, this paving only lost 0.4 Mpa of flexural strength. This result demonstrates excellent paving resilience
This paving has a slip resistance PTV rating of 60 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

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. Edges may be handcut or sawn and may include slight irregularities such as chips and blemishes either from the manufacturing process or as part of the natural make up of the stone. 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 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.
- Smooth, Sawn Sandstone This sandstone has a level, smooth surface and most often, machine cut edges to give an simple appearance suited to modern, contemporary styles. The surface texture is smooth to the touch (honed) and is usually also produced in a calibrated thickness where the variation in the thickness of the slab is kept to a minimum to ease laying.
- Textured or Sandblasted, Sawn Sandstone This sandstone has a level, but textured, lightly stippled surface and most often, machine cut edges to give an simple appearance suited to modern, contemporary styles. The surface texture feels like sandpaper to the touch and provides non-slip qualities. It is usually also produced in a calibrated thickness where the variation in the thickness of the slab is kept to a minimum to ease laying.
- Flamed, Sawn Sandstone This sandstone has been sawn flat on the surface, but then, hot wax is poured onto the stone and burnt off. This causes the softer minerals to melt away, leaving an attractive subtly rippled surface. This paving is ideally suited to contemporary styled designs, however would work equally well where a softer, riven surface is desired. This paving is generally calibrated in thickness and therefore, easier to lay.
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 colour intensity increases when the paving is wet. Most brands offer the same range of colours with slightly different names. 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.
