Ledgestone retaining wall repair in Colorado: Why you should compact the trench? Compact the soil in the trench bottom with a hand tamper or vibrating plate compactor. This step is often neglected. The excavator, and even hand shovels, can disturb and loosen the top inch or two of soil, and that’s enough to make your wall settle—settling is bad! Our experts prefer crushed stone for the base rather than naturally occurring gravel dug from a pit. Crushed stone is a little more expensive. However, it provides better drainage, and because of the sharper angles on the stone, it requires less compacting, and once it’s compacted, it stays that way.
First of all, what is No Fines Concrete (NFC)? Basically it is just what the name suggests, concrete without any fine aggregates or sand. It consists of generally an aggregate (gravel), cement and water. The aggregate is coated with the cement slurry binding it together, it dries with the strength of concrete but with voids or air pockets. This makes the NFC light weight and allows water to pass through its honeycomb texture.
We also repair existing retaining walls. Many railroad tie walls or older concrete retaining walls which may or may not include rocks or boulders are beginning to show signs of failure. Often times a homeowner will build a DIY retaining wall that needs help after years of service. Colorado Retaining Wall specializes in the building and repair of retaining walls. Whether the wall is for a backyard or driveway of a residence or a commercial Shopping Center, we design and build large block walls for all Earth retention requirements. We have the ability to fortify the wall with shotcrete or soil nails which would include helical tie-backs or micropiles. Nearly every wall we build requires engineering and we have deep relationships with engineers that work hand-in-hand with our foremen regardless of the size of project. Please read our reviews and look and our photo gallery. See additional information on Colorado Retaining Wall Builder.
To ensure the utmost strength, any wall taller than four feet should be carefully designed prior to installation. You have to consider structural reinforcement, drainage and the wall’s overall stability. Tall walls should all be designed for a “battering” effect, where the courses are set back from one another. In other words, the wall slants backwards as it gets taller. This battering effect adds life to a wall that may eventually tilt forward over time from the pressure of the earth behind it. Although battering is one method of strengthening a wall, most segmental systems incorporate this approach in conjunction with the other reinforcement measures mentioned above—reinforcement grids, anchors or steel reinforcement.
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.
