Boulders and Fieldstones give a sense of old world charm into modern day times. The sizes can vary from 50lbs to to pieces so large that you need a machine to move them! Boulders and fieldstones can be used to construct beautiful walls, water features, stone benches, accents, and stunning centerpieces. Garden boulders range from approximately 8" to 30" in diameter and are an essential construction material for natural ponds and waterfalls.
