Sandstone Rock Boulder & Sandstone Log Retaining Walls

Transform your sloping or waterfront site with premium sandstone rock boulder and sandstone log retaining walls that stand the test of time. At Coastrock & Earth Excavation, we don’t compete on price—we compete on quality, durability and visual impact.

Built for Longevity

Built on a solid footing base and crafted from locally sourced sandstone, our walls resist lateral soil pressure, marine conditions and weathering for decades.

Natural Aesthetic

Each boulder and log is hand-selected and precisely positioned to blend seamlessly with your landscape. Over time, native mosses and plants accentuate the wall’s organic character.
