Landscapers can harness the versatility of aggregate sandstone to create stunning outdoor spaces. From natural-looking pathways and decorative ground cover to erosion control and water features, this material offers both aesthetic appeal and functionality. Larger sandstone blocks or cut pieces excel in constructing raised garden beds and retaining walls, adding structure and visual interest to landscapes. The varied colors and textures of sandstone complement different design styles, from formal gardens to rustic settings, while its durability and weather resistance ensure long-lasting beauty with minimal maintenance.

In modern construction, sandstone aggregates play a vital role in both structural and aesthetic elements. Building facades benefit from sandstone cladding, offering durability and natural beauty that develops a unique patina over time. For flooring, crushed sandstone can be incorporated into concrete mixes or used as larger tiles, providing slip resistance and elegance in various finishes. While not typically used for primary support, sandstone aggregates contribute to concrete mixes for structural elements, adding strength and visual interest. The material's versatility shines in decorative features, where it can be carved into intricate moldings, columns, or sculptures. In paving applications, crushed sandstone aggregate offers excellent drainage and stability for driveways and outdoor surfaces.

In road construction, sandstone aggregates provide a stable base layer and can be incorporated into asphalt mixes for durable surfaces. Bridge construction relies on these aggregates in concrete mixtures for decks, piers, and abutments, while also utilizing them in approach embankments and gabion baskets for erosion control. Railway systems benefit from crushed sandstone as ballast, offering stability, drainage, and resistance to degradation under heavy loads. Large-scale erosion control projects employ sandstone in riprap for shoreline protection, gabion walls for slope stabilization, and as fill material in geotextile systems. These applications showcase sandstone's versatility in creating resilient infrastructure that can withstand environmental stresses and heavy use.

Beyond construction and landscaping, aggregate sandstone finds applications in various specialized industries. Its porosity makes it an effective medium for water filtration systems, used in both drinking water and wastewater treatment processes. High-purity sandstone provides the essential silica for glass manufacturing, contributing to the production of window panes, specialty glass, and glass fibers. In metal casting, certain types of sandstone are processed into foundry sand, offering excellent heat resistance and dimensional stability for creating molds and cores. The oil and gas industry utilizes specific grades of sandstone as proppants in hydraulic fracturing operations, helping to keep fractures open and improve extraction efficiency.
