Concrete Block Paving is made from natural materials and variances can occur in colour. The amount a product is rumbled may vary from batch to batch and product to product. It is recommended that when blocks are laid they are taken from at least 3 packs to minimise any “patching” that may result in slight variances in colour in individual packs.

If you require a particular product, but the desired colour is not listed for that product we can manufacture any of our products in any of the colours in our colour range if a reasonable quantity is required.

If there are loose pavers these should be reset but only after ensuring that there is no underlying reason for the looseness which may require the area being re-laid.

If there has been loss of jointing sand then more sand can be brushed in but only after checking for the reason of the loss of sand. If the loss of jointing sand is due to movement /settlement then the paved area would require the area to be relaid.

The decision to seal or not to seal is a matter of personal preference. There are a number of proprietary block sealing products available on the market.

Most sealants contain fungicides which restrict the development of vegetation, protect the pavers against oil and other stains, and may act as a colour enhancer. It is important to get the right sealer for what is required – the top quality sealers are longer lasting whilst being more expensive.

The process of producing Rumbled products may result in them being covered in a light dust. The dust will naturally wear off, alternatively pressure washing them will have an instant effect. This should be done prior to filling the joints with dry sand.

In common with other concrete products with a high cement content pavers may exhibit the temporary surface phenomenon of efflorescence. This may appear as a milky white stain on the face of the product or the appearance of the paver is that the colour has faded. This is no way detrimental to the performance of the product and responsibility cannot be accepted for its occurrence. Efflorescence will wear off or to accelerate the process can be cleaned off with a proprietary brick cleaner.

There are a number of proprietary brick cleaners available on the market. The manufacturers instructions should always be followed, in particular the product should be tested on a unobtrusive area of paving to ensure that it does not affect the paver detrimentally.

Regular brushing with a stiff brush is the best way to keep your paving clean. Treatment with a weedkiller annually will minimise the vegetation growths during the year.

Oil Stains - If there is an oil patch then the excess oil should be lifted off using an absorbent powder – it should not be rubbed in.

The resulting oil stain can then be cleaned using an emulsifier to lift out the oil from the paver. Finally the area should be washed with a detergent solution and then rinsed thoroughly.

Chewing Gum - To remove first use a freezing agent on the offending gum, and then scrape it off.

Rust Stains - Try and avoid rust stains as these are iron oxide which is in fact what the colour used in the block paving is made out of. Therefore any cleaning products used to remove the rust may also affect the colour of the pavers. It is recommended that the area affected be scrubbed with a hard or wire brush to remove the worst of the stains.
