Paving and stone products should be assessed according to whether an issue materially affects normal installation, intended use, structural performance or the reasonable finished appearance. Minor cosmetic differences or natural variation do not automatically mean that a product is defective.
Paving slabs, porcelain, natural stone, split face tiles, stone cladding, setts and steps are heavy construction materials. Natural products can also vary in colour, texture, thickness and geological appearance.
When Is a Product Issue Significant?
Further review may be appropriate where a genuine issue prevents normal installation, significantly affects intended use, or makes material structurally unusable. Examples may include substantial manufacturing problems, major breakage, incorrect products or significant transport damage.
Each case is considered according to the type of product, quantity affected, intended application and available evidence.
Natural Stone Variation
Natural stone is not identical from one piece to another. Colour variation, veining, fossils, mineral markings, surface texture, natural pits and slight differences in size or thickness are normal characteristics of many stone products.
Product dimensions are generally nominal. Calibration improves consistency but does not make natural stone perfectly uniform.
Minor Chips and Edge Damage
Heavy paving products pass through manufacturing, packing, pallet handling, transport and site movement. Small chips to corners or edges can occasionally occur.
Where a slab remains structurally sound and can still be installed normally, minor edge damage will not usually require replacement. Major breakage or structural damage that makes a product genuinely unusable should be assessed separately.
Stone Cladding and Split Face Tiles
Stone cladding and split face tiles are commonly assembled from several pieces of natural stone. Small differences in mesh, backing or manufacturing adhesive can therefore occur.
Further review may be appropriate where backing failure or detached pieces materially prevent normal handling or installation.
Installation and Product Issues
Problems appearing after installation are not necessarily caused by the paving itself. Bedding, sub-base preparation, drainage, jointing, slurry primer, contamination and site movement can all affect performance.
Staining can also result from mortar, jointing products, soil, leaves, oils, cleaning products or sealers. The likely cause should therefore be considered before the material is classified as defective.
Weathering and Outdoor Use
Outdoor paving and stone are exposed to rain, sunlight, frost, pollution and organic growth. Changes in tone, patina, algae, moss and general weathering can develop naturally over time.
Information Needed for a Claim
Customers should normally provide the order number, product name, quantity affected, a short description of the issue and clear photographs. Where relevant, wider photographs of the installation may also be helpful.
Refund, Replacement or Other Resolution
Where a genuine product issue is accepted, the appropriate solution will depend on the nature and quantity affected. This may include replacement of affected products, a partial refund, credit, compensation or another reasonable solution.
A resolution will normally reflect the quantity actually affected rather than automatically applying to the complete order.
Check Products Before Installation
Customers and installers should inspect materials before cutting or installation. Natural stone should also be blended from different packs to distribute colour and texture naturally across the finished project.
If something appears genuinely unusual or likely to prevent normal installation, contact the supplier before installing the affected material wherever practical.
General Claims Principle
The main consideration is whether the issue materially affects installation, intended use, structural performance or the reasonable appearance of the finished project.
Normal natural variation, minor dimensional differences, small edge chips and limited manufacturing variation are not automatically product defects. Genuine material issues should be reviewed according to their actual effect and the quantity involved.
