With any surface, a level of maintenance is required to maintain a good upkeep of the product.
Some stains are harder to remove than others. Oil spills can be difficult to remove. We would recommend a product called LeoTack, which is applied with a stiff hand brush. In extreme cases, blocks can be lifted and replaced.
Here is some advice on how to maintain your block paving driveway:
When the surface has been laid, a kiln dried sand is gently swept into the surface. Should the "gaps" reappear in time, then a gentle sweep of the kiln dried sand should be applied (sourced from any builders’ merchants).
For block paving driveway maintenance there are a wide range of sealants available to protect the completed paving and these can help to repel oil, dirt and weeds. Always try a test area first as most sealants will alter the appearance of the blocks.
There are natural elements which can also cause a stain on the blocks, such as efflorescence. Efflorescence is a white crystalline deposit that occurs naturally on the surface of concrete materials. Unfortunately, with this being a natural process we cannot foresee this occurring. If it occurs, efflorescence may mask the colour of the product for a period of time, but tends to be washed away gradually by rain and day to day use.
