Firstly, let’s start with one of the most expensive options. Natural limestone paving, slate or bluestone (and there are many more natural stone alternatives to choose from) all look magnificent when laid, but the process to get to the final result will be costly (both in terms of product and installation) and complex.
Natural stone, unlike other man-made decking alternatives, such as composite decking, needs to be sited on a solid base and this often requires lots of heavy excavation groundworks. And, if you are installing the stone decking yourself, you’ll need to be strong and experienced at handling this material as stone can be heavy, difficult to manoeuvre and not easy to cut.
Pros: Look great. Retains looks over time.
Cons: Expensive product. Complex to cut and lay. Weed growth will appear between stones. Surface often is uneven (making it unsuitable for anyone unsteady on their feet).
