Artificial rock has huge advantages and endless applications over real rock, both structurally and aesthetically.
The seamless design eliminates leaks in water features and there are no unsightly mortar joints between
the rocks.
Their "footprint" to weight ratio eliminates the settling process and there are no limits to the size and
scale.
Sure real rock can be stacked into a wall but try moving a section of a cliff from the stream bank and placing
it in your landscape.
How about boulders to large for even the biggest machinery to place.
Artificial rock built to look, feel and weather just like the real thing.
Water features, retaining walls, cliffs, planters, light covers, caves, stairs, bridges, etc. etc. etc.
Now you can do all this and much more! The only limitation is the imagination!
