Sandstone rocks are sedimentary rocks and often
form in layers. The use of this stone is from
ancient times.
For thousand and millions of years, little
pieces of our earth have been eroded and worn
away by wind and water. These little pieces of
earth are washed downstream where they settle to
the bottom of the river, lakes and oceans which
are called sediments. Layer after layers of
sediments are deposited on top of each other.
These layers are pressed down more and more
through time, until the bottom layers slowly
turns into rock.
A natural stone that is quartz-based consisting
chiefly of quartz grains with various types of
cementing materials. The purest sandstones are
nearly white, with colours primarily due to iron
oxides, limonite and hematite yielding yellow,
pink, brown, buff and reds.
Our Sandstones are generally mechanically very
strong with small grain sizes and a high degree
of cementation that allow some types to be
finished as mirror polish for internal
applications.
This stone is widely used as building stone as
well as facing and roofing slabs. |
