Black Limestone is a popular choice particularly in heavily planted gardens as the dark slabs offer a contrast to floral areas. Black Limestone paving slabs are perfect for areas where slate is prevalent and where a contrasting colour is required from light to dark. This Natural Limestone paving fades in colour over a time, so to ensure that it retains its colour we recommend sealing the paving or setts with colour enhancers as soon as possible after installation. This prevents the Limestone paving from fading, preserving the deep jet black colour. It is also commonly used around ponds and water features. It is very distinctive and creates a modern look.
