Strata Porcelain paving is durable and easy to maintain in your garden as porcelain is highly resistant to staining or the growth of moss and algae.
Volcanic Grey is a new porcelain that has been designed to give a mix of dark grey swirling tones for a stylish, low maintenance paving material. Volcanic Grey comes in shades of predominantly dark grey with lighter grey banding.
Available in 20mm thickness.
This paving is flat surfaced with lightly textured finish.
Colour Variation
Low Variation
This paving has a low amount of colour and shading variation present within the range
Water Absorbency
Low Absorption
During tests, this paving absorbs less than 0.09% 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% and natural stone, 1-2%
Flexural Strength
Excellent
During testing, this paving showed flexural strength of 40.5 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 strength of 5 Mpa
Frost Resistance
Great
During a repeated test cycle of freezing and thawing, this paving did not lose strength. This result demonstrates excellent paving resilience
Slip Resistance
Low Risk
This paving has a slip resistance rating of R11. This rating means the surface is slip-tested for use on flat ground when wearing footwear in both wet and dry conditions, indoors and outside
Dimensional Tolerances
Non Rectified
This paving is classified as 'non rectified' meaning it is cut to size prior to firing in the kiln and may expand/contract during firing. As a result, it has dimensional tolerances between individual slabs of up to 5mm +/- and jointing allowances should be gauged accordingly. Note, slab sizes quoted are nominal and work sizes are often up to 5mm smaller than those stated
Body Colour
Colour Bodied
This paving is 'colour-bodied' meaning it is vitrified throughout and the body colour is a similar tone to the upper face. This is important as if surface damage were to occur, the colour of the under layer will be a similar shade
Bullnosing and Exposed Edges
Central Vein (black heart)
Some vitrified paving has an occasional central vein running horizontally through the body of the stone which is more prominent when the stone is cut. It is therefore recommended that a cut edge is not used for very specific applications where an exposed edge is required such as bullnosed steps

Material Information
Porcelain, Ceramic and Vitrified Characteristics:
Porcelain, ceramic and vitrified products are manufactured from naturally occurring aggregates, cement and binders, all of which are subject to colour and texture variation. Variation in colour and dimension may occur between batches of the same stone, although this type of material is relatively consistent in colour tone. Some manufacturers include the pointing allowance in the individual slab sizes whereas others include the pointing allowance in the overall pack coverage and as with all paving materials, dimensional variances may occur. 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 features.
Porcelain, Ceramic and Vitrified Description:
Porcelain, ceramic and vitrified paving is a manmade paving material, constructed from naturally occurring kaolin clay materials and minerals such as quartz and feldspar which is then fired at 1200 Celsius to offer an extremely hard-wearing and low-maintenance paving product suited to both indoor and outdoor applications. Its low water absorbancy means it attracts very little residue or algae, but regular care and maintenance is requied for surface grime and dirt. Vitrified products are lightly textured to improve slip resistance and the dimensions are more accurate than those seen with natural stone paving.
Porcelain, Ceramic and Vitrified Colours:
The colours of this material are uniform with a subtle, evenly distributed variation. Many of the products offer the same colour palette as its natural stone equivalent without the irregular characteristics found in the natural stone paving material making it especially suited to clean, contemporary design schemes.
What's the Difference between Porcelain and Ceramic Paving?
The appearance of ceramic and porcelain paving is quite similar, however the manufacture and performance of each varies. The key differences are:
- Porcelain is made from a finer clay than ceramic and is fired at a hotter temperature for a longer period of time. This makes it a harder paving stone
- Porcelain is less porous than ceramic. Lower porosity means less cleaning
- The colour patterns on porcelain are ink printed and penetrate through into the top layers of paving whereas ceramic paving has a colour pattern transfer laser printed onto the surface. This means the porcelain paving performs better against chips or scratches
