Pentablock is able to create a truly beautiful effect with a zen finish in water features and garden applications. In response to water features the core fill creates a result that allows the system to retain water immediately. The running water on the head unit does not effect the natural stone as Pentablock uses ancient stone that has naturally formed and so its own strength can repel and carry the consistent run of water for a lifetime. The natural stone and its patented fixing system helps the elements be contained within the desired water feature and garden box design. The finished look can be custom finished with the choice of natural stone capping that will create a look that is suitable for its surround but guarantee a look that is unique for your needs. Pentablock has created a system that is completely modular and can be used to build an unlimited range of garden and landscape features. Pentablock not only creates beautiful stone planter boxes, garden edging, fire pit stands, outdoor BBQ and fireplace/pizza oven surrounds.
