Cobblestone retaining wall building provider in Colorado: 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.
NFC can either be mixed on-site for smaller areas or purchased from a reputable concrete supplier and trucked in for larger commercial applications. NFC is mixed at a 6:1 ratio by volume of 20mm max size clean aggregate and cement. Water content should be such that the cement slurry evenly coats the aggregate and retains a wet/glossy appearance without excess slurry running off, this is typically around 40 litres per 100kg of cement. With the use of NFC, we are able to build Block Retaining Walls in areas and situations where normal construction methods would not work. Some of these situations are: In areas where excavation behind the wall is limited either due to being on a boundary or close to other structures or footings.

Yards are like people, they come in all shapes and sizes. Some folks are fit, others are flabby. Some yards are flat, others are hilly or sloped. And, like people, some yards could use a little work. When necessary to create a level surface on a slope, building a retaining wall has been the answer for thousands of years. These walls literally retain the earth to create flat, appealing lawns and stepped areas of land. Depending on the weight the wall must support, a wide variety of materials can be used to construct a wall, from brick and mortar to landscape timbers. In the South, many yards even feature garden-style retaining walls built from discarded railroad ties for a rustic, country appearance.
A wall that leans into the soil it retains is less likely to be pushed outward by soil pressure than a plain-old vertical wall. Design and build your retaining wall to slope at a minimum rate of one inch for every one-foot of rise (height). Fortunately, working with retaining wall blocks makes it incredibly easy to achieve this “step-back” construction! The locking flange on the bottom edge of every block guides it to click into position slightly behind the lower block, preventing the top blocks from being pushed outward.
