Cobblestone retaining wall repair company in Colorado: Ensure you order everything you need at once and set aside an allowance for breakages and cutting. Contrary to popular belief, building a fence on top or behind a Block Retaining wall is rather easy. In some cases where only a small amount of retaining is required as in 200-400mm, the fence can be built directly on top of the wall with the fence posts passing through the walling blocks and concreted into the ground as normal. This method would be ok to use with all forms of fencing such as post and rail, colour bond post and rail, good neighbour fencing, tubular panel and even pool fencing.
If you’re building tiered retaining walls, set each tier back far enough to prevent the weight and pressure of the wall above from destroying the one below it. The rule of thumb is to separate wall tiers by a distance that’s no less than twice the height of the wall below. So if the bottom wall is 4 feet tall, the wall above it should be built at least 8 feet behind it. Walls more than 4 feet tall will likely require a building permit and a plan made by a licensed engineer. The engineer will specify the base’s width and depth, how far down the base course should be buried, and whether or not a geogrid (soil reinforcement system) should be used.
DO start with a good foundation. Your retaining wall will only be as strong its support system. For a stacked-block retaining wall that’s no higher than four feet, a trench filled with three inches of crushed rock will help keep the wall from shifting and settling. The exact depth of the trench depends on the proposed height of the wall, but follow this rule of thumb: Dig a trench to be an eighth of the wall plus three inches. For example, if you want the finished height of your retaining wall to be three feet (36 inches) tall, you’d need to dig the trench eight inches deep to accommodate three inches of crushed rock and about five inches (or an eighth of the visible retaining wall) to start the wall below grade.
The latest technology in retaining walls can be seen in the variety of segmental systems featuring blocks that interlock, with no need for mortar. These systems enable you to finish a project that will look complicated and professional. The simplest DIY systems are ideal for short walls (approximately 3 feet high) and feature blocks with a lip on the lower, rear edge that locks them together for a stepped effect. When the cavity behind the wall is filled with earth, the pressure pushes the blocks forward, strengthening the joints between the lips and the blocks beneath.
