Unknown Facts About Limestone Walls

Just by way of a little light diversion, we at Downunder Contracting thought we’d share a few facts about limestone and limestone walls, Albany residents might not have known.

  1. It’s typically mainly organic sedimentary rock. It’s often made up of the remains of organic matter laid down in wet conditions or calcium carbonate that has been precipitated from water over geological time periods. So, coral, sea shells and so on.  Once upon a time, a hefty chunk of your limestone wall might have been alive!
  1. When used in architecture, such as for limestone walls, it’s usually slightly cheaper to take larger block sizes than smaller. That’s because the cutting work required for larger blocks is less.
  1. Lime is a natural neutralizing agent for acid.  That’s why powered limestone is sometimes used in agriculture for helping to remove acidity from soil.
  1. The mining industry sprays limestone onto the walls of mines. It’s pretty inert and that helps to reduce the risk of explosions.
  1. The outer covering layer of the Pyramids in Egypt was originally polished limestone.  So, if it was good enough for the Pharaohs, could it be good enough for your garden?
  1. Stalactites and stalagmites (back to school-days mnemonics to remember which is which!) found in caves are usually limestone deposits.
  1. The chalk sticks sometimes used even today on blackboards are a form of limestone.
  1. You might think that limestone is usually white or a yellow-white but in fact impurities can mean that it’s sometimes black, red, brown blue or grey – at least in tint.

Of course, interesting as the above facts are, it’s usually the strength, versatility and beauty of the stone that makes it so popular for retaining walls and other parts of both the external and internal aspects of domestic and commercial property.

We’d love to hear from you and tell you all you want to know about this fantastic natural material.
