Limestone is a kind of sedimentary stone that is very common all over the Mediterranean and Europe. Limestone
is made out of the shells of zillions of little tiny sea snails and creatures which lived in the sea billions of years ago.
When they died, they fell to the bottom of the sea and rotted, but their shells, which were made of calcium, did not
rot and just stayed there. Pressure from other shells, and from the water, and from sand being washed over the shells,
squashed them all together into rock. Many years later, the sea changed where it was, and all this calcium-rock (limestone)
was left on the land where people could quarry it. When limestone gets even more squashed, it can turn into travertine or marble.
The beige and pale yellow hues of limestone are very trendy nowadays, but limestone’s flexural strength demands thicker
panels for wall cladding, as much as 3”-4”. This is a small sacrifice; limestone looks stunning on exteriors. Limestone in
applications exposed to soil need an alternative stone for the base course to solve the problem of its high absorption rate
and low stain resistance. You will need to check the properties of the limestone you’re using to ensure it is appropriate to
the outdoors.
