Limestone restoration brings tired limestone structures back to life. Limestone is soft and very porous and requires ongoing maintenance. There are several grades of limestone which is why some limestone structures deteriorate and others don’t.
Repointing limestone is a very similar method to repointing bricks. Limestone requires more lime in the mortar mix and more water to prevent cracks from the mortar drying too fast.
Restoring the blocks varies to how much damage there is. With our specialized skills, we make a reconstituted limestone mix and build up the face of the block.
What causes limestone to deteriorate?
Carbon dioxide in the air dissolves in the rain water becoming weakly acidic. The carbonic acid dissolves limestone as it seeps through the cavities.
