Stones and Boulders are extremely popular lanscape features. Oasis Advisors builds retaining walls using limestone, sandstone, and natural Michigan granite boulders. They add texture and interest while working to keep your environment balanced. Aesthetically, boulders can be outcroppings or focal points within your plantings. Limestone or sandstone may also be used in lieu of wood for steps, stairs and for small bridges. Because stone needs virtually no maintenance, it lends itslef as an exceptional, durable material that's ideal for all seasons.
