Natural paving materials

Due to the composition of natural stone, colour variations may occur after installation. The effect of the cement content in the pointing and base material may result in the temporary effect of efflorescence

Cleaning &  Maintenance

To keep your paving looking good, cleaning with a stiff broom and soapy water should be used. Regular use of a pressure washer may dislodge the material in the joints and ultimately affect the surface of the paving. NEVER use acid based cleaners on natural stone as this will have a detrimental effect on the product. Ordinary salt should not be used on Limestone products. We recommend that a proprietary brand of de-icing be used on all natural stone products

Concrete  paving materials

Medium level maintenance is required once laid. Sweep occasionally to remove dust and detritus. If you find green algae building up on them, it can be safely removed by cleaning or, we are told, by swilling the area with Jeyes Fluid to kill the algae, which can then be swept away after a couple of days. Use of a pressure washer should be limited to very dirty pavements and no more than once a year, as the high-power water jet loosens jointing and can damage some pavings.
We recommend that block or brick paving be treated twice a year with a general weedkiller such as Sodium Chlorate, to deter mosses and weeds from setting up residence in the sand joints
It’s worth noting that, generally speaking, weeds grow INTO paving, not through it, unless it has been really badly laid. The claims made regarding the necessity or value of “weed barriers” beneath block paving are spurious and should be treated with caution.
