Terms & Conditions


Core Terms (Paving & Walling)


All products should be carefully inspected for defects or damage upon delivery and prior to being laid or fitted.

Product Information
Within Wyresdale, design and development of products is a continuing process, and product information is subject to change without notice. Accordingly, please check with Wyresdale to ensure that the product information you have represents the most up-to-date product information.


All products should be installed in accordance with the latest British Standard.


Wyresdale produces paving and walling products with excellent density and durability, however, as with all concrete products, slight colour variations are inevitable. Although every effort is made to ensure consistency of product colour, variations can occur. In particular, single colours such as Buff, Natural and Red will have variations.

Wyresdale therefore recommends that products are thoroughly mixed on site by drawing from a minimum of four pallets. We would always recommend that when purchasing products, especially in larger quantities, that they are all ordered and manufactured in one batch to reduce the chances of getting colour variation. Please note that the colour of new products will inevitably vary compared to those which have been installed for a period of time as weathering does take place. All colour illustrations in Wyresdale’s brochures are as accurate as the printing process will allow. For a more accurate colour match please refer to actual product samples, which can be provided.


Efflorescence is a white crystalline deposit that occurs naturally on the surface of concrete materials. Wyresdale use market leading technology to significantly suppress the occurrence of efflorescence, however, if it occurs, it may mask the colour of the product for a period of time, but tends to be washed away gradually by rain. Wyresdale do not replace products with efflorescence. Packs of products which have had packaging removed should always be re-covered with appropriate packaging to prevent the occurrence of secondary efflorescence.

Surface Scratches

Minor scuffs or bruises may occur during delivery, movement onsite, and installation (for example, during any plate vibrating process). In Wyresdale’s experience, these marks usually weather off through time.


To avoid waste, please ensure that your contractor accurately measures the area on site before ordering products. In Wyresdale’s experience, dimensions taken from a project plan can vary significantly from the final layout.

Manufacturing & Quality Systems

Wyresdale uses an integrated management system to manage all health & safety and environmental issues.

Product Maintenance

Routine cleaning and maintenance is required to keep the overall appearance of products in pristine condition.Laying multi-blend coloured paving blocks, flags and walling products To achieve an even blend of colour when laying multi-blend paving blocks, flags and walling products, it is desirable to mix from three or four different pallets.

Initial Cleaning

When an area has just been paved, allow it to settle for a few days. After this, you may wish to lightly hose down the paving to remove any excess sand or dirt. The area should then be treated with a weed killer suppressant two – three times per year as required.

General Cleaning

Paving requires regular maintenance, including regular sweeping to prevent the build up of detritus. Wyresdale recommends that paving is cleaned two – three times per year. For general cleaning of dirt and algae, vigorous brushing with a stiff yard brush with plenty of hot detergent solution (washing up liquid or nonbio washing powder), thoroughly rinsed with clean water, should suffice. Repeated treatment may be required for paved areas sited beneath trees or in permanent/near permanent shade. A light power hose at medium pressure is generally all that is required to clean general dirt and grime. Any jointing material which is removed must be replaced. Do not use high pressure powerwashers as aggressive powerwashing can damage the product surface. A trial area should be tested before large scale powerwashing takes place.

Moss, Lichen and Algae

Thick growths of moss or lichen must be removed first by scraping out the joints and then treating the area with a moss killer such as anti-moss paving cleaner. Anti-moss is designed to remove moss, lichens and algae. It is best applied in dry weather. After being applied it will take a few days to be fully effective. Once the moss and lichens have been killed, they can easily be brushed off. Anti-moss also leaves a residue in the sand joint which will help reduce the likelihood of re-growth. The manufacturer’s instructions should always be followed when using any cleaning agent.


Large weeds should be removed by hand and then the area treated with a weed killer (available from any good garden centre). Smaller weeds can then be treated directly with weed killer and these weeds should start to die within days. The manufacturer’s instructions should always be followed when using any weed killing agent.
