Important considerations in constructing a limestone retaining wall are foundation, backfill, block size and anchoring system. Foundation. Prior to placing the first layer of limestone block, remove all topsoil and soft subgrade material. A 6- to 12-inch layer of crushed limestone should be placed and compacted for the wall's foundation.

Basic Design Principles and Operation. Limestone sand is placed directly into the streambed of high-gradient headwater streams. The sand dissolves into the water column as it spreads downstream during high stream flow periods (see Figure 2). Dissolved limestone sand adds CaCO 3, which in turn results in higher pH and ANC and lowered aluminum ...
