Newly quarried stone may contain traces of quarry sap which generally takes between 12 months and 3 years to dry. Once this has dried out, limestone is at its hardest and most weather resilient.
In the UK, winter usually means freezing conditions and so until it’s laid, your limestone should be protected by a minimum of two layers of dry insulating material, dry straw or any other suitable material over which a polythene outer cover or tarpaulin should be provided to keep water out.
Where limestone is laid on the ground, for example, as garden step rises, you’ll need to protect the stones from rising damp, using a plastic membrane.
If you’re thinking of path edgings, pond surrounds or external floor tiles, limestone may not be the most suitable material. Ask our experienced stonemasons for advice.
There’s a certain technique to dry stone walling – larger stones should be concentrated to the bottom of the wall diminishing in size as the wall rises. No cement mortar should be used with the exception of a little mortar to the top copings, if necessary, in order to prevent them being removed.
You can buy chemical treatments to protect your stone from weather deterioration and acid rain.
