Retaining walls are not merely decorative garden features; they are highly engineered structures designed to hold back tons of soil and prevent catastrophic hillside erosion. The most common reason retaining walls fail, leaning outward or blowing out entirely, is poor water drainage behind the wall. To relieve the immense hydrostatic pressure caused by trapped groundwater, a wall must be backfilled with a specific drainage aggregate, not just the native dirt that was excavated. At Outdoor Warehouse Supply, we provide the essential clean, crushed stone needed to create a highly porous backfill zone that directs water down into a French drain system and safely away from the structure. When you are planning a serious landscape engineering project and are seeking a knowledgeable sand & gravel supplier, you must choose a partner who understands the mechanics of wall construction. We supply the "clean" stone—meaning it has been sifted free of the small fines and dust that would otherwise clog the drainage pipes over time. Additionally, we provide the heavy, compacted leveling pad materials required to set the vital first course of base blocks perfectly level. From the foundational trench to the very top layer of backfill, we have the immense volumes of aggregate required to secure retaining walls of any height or length. Ensure the safety and longevity of your structural investments by utilizing our premium, free-draining bulk materials for all your backfilling needs.
