Granite is widely used for umbrella bases. All our umbrella bases are manufactured from durable and tough granite, with a polished finish in black or natural colour. They come in a variety of weight options to ensure that the umbrellas of all sizes remain securely intact with style and practicality. Granite is also an excellent option for external table tops and work tops. Easy to clean and beautiful to look at, while less porous than other external stones such as marble.
