Water Feature Install Guide

The large 1350mm Slate Pyramid Water Feature is mainly dark and plum tones when wet, and it will dry a lighter, brighter blue / grey colour. Read this 1.5m Pyramid Case Study for ideas on how to install this type of feature into a garden design.This is a significantly large sized garden ornament and makes a striking feature in any extensive garden or landscape design. It’s suited to grand patio projects and water feature developments, and can be integrated easily with large pond designs. The slate landscaping rocks are core drilled to allow them to sit on our stainless steel base plate (included) which gives the stack security. The feature requires a reservoir and pump set up to complete the waterfall functionality. Customers are welcome to source their own reservoir and pump but we recommend adding our Pack, available in the basket when purchasing.
