Description:
Portland limestone which has a low saturation coefficient (<0.72), a low microporosity (<11.0 of the stone by volume) and an open oolitic structure generally perofrms well over long periods when used on buildings.
Based on current research it seems likely that the stone would weather at a rate of between 1 and 3 mm per 100 years but it could be greater in severe exposures.
Overall, should be suitable for use in most aspects of construction including flooring, paving, load bearing masonry and cladding including areas where a long service life is needed or where high salt concentrations are expected.
