Ledgestone retaining wall construction in Colorado: By using NFC you are basically increasing the depth of your retaining wall. Most masonry blocks would be an average depth of 200-250mm, by using NFC you are increasing that depth of your solid masonry block from 200mm up to 500mm (Infill depth) or more depending on the height of your wall. It is always recommended that every third or fourth block should have part of the back edge removed. This would give a far better adhesion tying the NFC infill layer and the NFC core filled blocks creating a far stronger structure.
Anyone with a strong back can stack up a bunch of blocks and build a pretty stone retaining wall. But it takes skill and planning to construct an attractive wall that can also handle immense pressure, shrug off the forces of gravity, stand for decades and laugh in the face of Mother Nature. That’s the kind of wall we wanted to learn how to build, so we went to work with some hardworking hardscaping pros. They showed us that it’s all about a solid base, proper drainage and the right materials for the job. They also shared a few handy tips they’ve picked up over the years.
After your drainpipe is in place, you should backfill the rest of the space behind the blocks with either sand or pea gravel—either will allow water to filter through to the drainpipe at the base of the wall. For the best results, backfill with a few inches of the material after laying each course of blocks, and use a hand tamper to compact the material. By tamping the backfill every six inches or so, you’ll ensure that it is packed tightly, which will provide additional support from the pressure of the soil behind the wall.
Some of the simplest walls are “gravity” walls built of loose block. These walls depend on the mass and weight of the blocks to retain the earth. Landscape blocks are simply stacked one course on top of the other, with the joints staggered and each course slightly stepped back from the course beneath it. These small walls are used to retain small areas of earth, as seen with flower beds surrounding tree trunks. These simple designs usually work fine in a low-traffic area for a wall that doesn’t exceed about 2 feet high. Walls built with a combination of concrete block, mortar and rebar are also popular for small yard projects. The mortar and steel rods lock the blocks together for additional strength.

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.
