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.

Queries & Complaints
Please contact one of Wyresdale’s Paving & Walling Centres with any queries or complaints.
Any complaints must be notified to your supplier without delay.

Product Maintenance
Light coloured paving blocks and flags emphasise tyre marks and oil spills on the driveway. Please note that
these products will need more maintenance if overall appearance is to be maintained.

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
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.
