Instructions & Warnings

As referred to in our Conditions of Sale.

CORE TERMS (PAVING & WALLING)

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

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

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

Colour

Tobermore 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 Golden, Buff, Natural and Red will have variations. Tobermore 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 Tobermore’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
Efflorescence is a white crystalline deposit that occurs naturally on the surface of concrete materials. Tobermore 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. Tobermore 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 installation (for example, during any plate vibrating process). In Tobermore’s experience, these marks usually weather off through time. 

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

Manufacturing & Quality Systems
Tobermore is a BS EN ISO 9001:2000 and BS EN ISO 14001 registered company. Tobermore 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 3 or 4 different pallets.

Queries & Complaints
Please contact one of Tobermore’s Paving & Walling Centres or offices (contact details at www.tobermore.co.uk) with any queries or complaints. Any complaints must be notified to Tobermore without delay.

CORE TERMS (PAVING ONLY)

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 2-3 times per year as required.

General Cleaning
Paving requires regular maintenance, including regular sweeping to prevent the build up of detritus. Tobermore recommends that paving is cleaned 2-3 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 non-bio 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 power-washing 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.

Weeds
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.

Block Paving Sealer
It is possible to seal block paving with a resin material which combats staining and weed growth and which also enhances colour and appearance. The acrylic sealer is sprayed onto the block paving and forms a ‘skin’ on top of the paving and the jointing material giving an easily maintained finish. The manufacturer’s instructions should always be followed when using any sealing agent.

FOR HYDROPAVE PRODUCTS

Tobermore recommends that its Hydropave products be installed in conjunction with a BS EN 7533-13:2009 designed permeable paving system. Please note: 

  • A permeable paving design relies heavily on using the correct aggregates. Prior to installation, we would ask you to test both the 4/20mm coarse graded aggregate and also the 6.3-2mm bedding and jointing grit as per the relevant British Standard specification (BS EN7533-13:2009). In particular, the material should be categorised as LA30, FI20 and MDE20 according to Table A.3, within this standard.   The grit should be insoluble in dilute hydrochloric acid and should be naturally occurring material.  In our experience, incorrect use of aggregates is one of the most common reasons for failure of a permeable paving design. 
  • All joints must be filled to the top with 6.3-2mm grit. Joints which are not fully filled can lead to possible movement of the blocks after use. We recommend that after a few weeks use that any joints, which have settled and are not full, are topped up with grit. Joints should be kept filled at all times. You need approximately 1 ton of grit for every 100m2 of 80mm paving. 
  • Care should be taken that the permeable joints do not become contaminated as work on the scheme is completed. Special care needs to be taken when soft landscaping is carried out so that soil does not enter the joints.

If any other design methodology is to be used, please take independent expert advice in advance. 

FOR FACING BRICK PRODUCTS

Installation – Facing Bricks
Tobermore’s Facing Brick products are designed to co-ordinate with standard cavity wall construction. When used in housing projects, a clear cavity must be retained. All work must be protected during construction and must be designed and built in accordance with accepted industry standards and practice. Builders familiar with conventional brickwork will find that similar installation principles apply.

Bricks should be handled with care and stored on a level, free-draining surface that is protected from the elements. Polythene wrapping provides protection from the weather. If this is removed it should be replaced or alternative protection needs to be provided.

When work stops or is interrupted by inclement weather conditions, brickwork should be protected immediately with polythene sheeting that is held in place with a suitable fixing. If new brickwork is not protected efflorescence, patchy mortar colour, patchy brickwork and staining can occur. It should be noted that laying of brickwork should be discontinued when the temperature falls below 3Oc or when frost is imminent.

FOR COUNTRY STONE PRODUCTS

Installation - Country Stone
Tobermore’s Country Stone products are designed to recreate traditional stone sizes and to co-ordinate with standard cavity wall construction. When used in housing projects, a clear cavity must be retained. 

All work must be protected during construction and must be designed and built in accordance with accepted industry standards and practice. Builders familiar with conventional brickwork will find that similar installation principles apply.

Joints can be finished flush or tooled depending on the overall effect required. Raked joints are not recommended. It is vital that all horizontal and vertical joints between Country Stone blocks must be compacted and free from voids. Shell bedding should not be used.

FOR PIETRA PRODUCTS

All natural stone products are porous and are subject to variation in colour, density, dimension and quantity. These inherent variations cannot be controlled nor the precise shade of the stone guaranteed. Tobermore’s selection process aims to ensure your natural stone products are as uniform in size and thickness as possible. However, because these are natural materials, the size and thickness may vary. This can normally be allowed for when the products are installed. Tobermore’s recommends that you take independent expert advice in advance of installing the products.

Colour
Tobermore recommends that products are chosen from, and verified against, actual natural stone samples, rather than the photography in Tobermore’s brochures.
It is fundamental to the character and appeal of natural stone that there are variations in texture, shade and tone between individual stones. For this reason, your contractor should use slabs or setts from several different packs to ensure a consistent blend of colours.

Weathering
As with all exposed materials, the products will weather over time. The nature and extent of any changes in appearance as a result of weathering will typically be dependent on a combination of:  location; degree of exposure; prevailing weather conditions; and/or quality of installation.

Sealing
Please note that the sealing of granite or sandstone blocks and flags can help reduce staining from coffee, wine and efflorescence. Tobermore can supply sealing agents if required. The manufacturer’s instructions should always be followed when using any sealing agent.

FOR SECURA PRODUCTS

Installation - Secura
All Secura products should be installed in accordance with British Standard BS8002. When constructing a retaining wall, ensure that you follow the design provided by the scheme engineer.
