Limestone paving - review

Landscape and Garden Product Directory

Limestone is a sedimentary rock consisting primarily of calcium deriving from the remains of marine animals. This origin gives limestone a geological fascination: a single block of limestone contains the remains of a million sea animals. When limestone is burned to make cement their structure is destroyed.

Limestone is white and hard, susceptible to damage by acid rain. Limestone is less popular as an outdoor paving material today than in the eighteenth century.
