Building Stone - Blue Lias
Blue Lias is blue-grey in colour which is provided by its iron content. It is popular in more modern-day surroundings where it is still used in the construction of new housing developments and extensions for existing buildings in conservation areas. Blue Lias is mainly used in flooring, walling and paving slabs - both coursed and layered. It is evident too in the making of flagstones and cobbles.
