Pavers can be made from concrete, clay brick and reconstituted and natural stone. Each of these materials has its own peculiar properties that need to be taken into account when deciding what material to use for any particular area of paving and what – if anything - to seal with.

Pavers have been used to provide aesthetically pleasing pavements by home owners, businesses and public utilities for so many years now that they seem almost to be ubiquitous.

With pavers available in a wide range of colours, shapes and materials, users can make any paved area look great as well as providing a safe, hard wearing traffic surface.

Where are pavers used?

One property that all pavers have in common is that the masonry they are made from tends to be porous. This can vary considerably from one type of masonry to another, but all are porous to some degree.

The more porous your pavers are, the more likely they are to absorb moisture and other liquids that might stain or contaminate the surface of the pavers.

Effects of moisture absorption

Pavers that have absorbed moisture can be affected by problems such as:
