Tools & Materials for Building a Retaining Wall


Building With Allan Block – Getting Started Once your project has been properly planned out and the designs are complete, you are ready to get started. It is always good practice to make sure that the materials you use are correct. Refer to the approved plans to make sure that the blocks are the right color, style and setback. Confirm the reinforcement grid is the correct strength, and size and inspect the wall rock and backfill materials to make sure that they meet the specified requirements. wall rock is used as base material, within the block cores as well as behind the blocks. Wall rock must be a compactable aggregate ranging in size from a quarter inch to 1 and a half inches in diameter. This balanced mix of sizes allows for good compaction. Wall rock serves many purposes in a wall project. When added to the block cores, it increases the structural stability , locking the blocks and grid together to form a “Rock Lock” connection. It also allows for good compaction inside and around the blocks and prevents settlement directly behind the block. There are three basic types of soils that can be found on any site, sandy soils, Clay soils or organic soils sandy soils, clay soils, or organic soils.The simplest way to determine the type of soil you have is to pick it up and examine it. Sandy soil, will not stick together. These soils allow for good drainage and are ideal for building walls Clay soil will stick to gether to form a ball. These soils retain moisture and may add pressure behind your walls. Organic soils will stick together but will not hold once the pressure is released. NEVER use Organic soils when building walls. If more detailed soil information is required, check with a local soils engineer for further testing. Be sure to have the proper tools on hand before you begin. See the guide for landscape walls for a complete listing of tools and equipment Remember, Safety always comes first. Use protective gear and be sure to follow safety guidelines when using power tools. For the next step in Plan, Design Build, go to Site Pre & Excavation or visit us at allanblock.com
