Pavers (flooring)
open-in-new
<p>A paver is a paving stone, <a href="/facts/Sett_(paving)/tfSH5KAy">sett</a>, tile, brick or brick-like piece of concrete commonly used as exterior <a href="/facts/Floor/BnhhyRJv">flooring</a>. They are generally placed on top of a foundation which is made of layers of compacted stone and sand. The pavers are placed in the desired pattern and the space between pavers that is created with the integrated spacer bar is then filled with concrete sand or a polymeric sand. No actual <a href="/facts/Adhesive/shTfIJ0E">adhesive</a> or retaining method is used other than the weight of the paver itself except edging. Pavers can be used to make roads, driveways, patios, walkways and other outdoor platforms. </p><p>In a factory, concrete pavers are made with a mixture of sand, stone, cement and iron oxide pigments in a mold and then cured prior to packaging. </p>
