Ledgestone retaining wall construction company 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.

Why you should backfill with stone? Versa-Lok recommends compacting the angular stone as you backfill, but check the installation instructions for the type of block you’re using. Backfill about 8 to 10 inches below the top of the capstones. This will allow enough room for the topsoil and turf. Secure the capstones with a specialty landscape block adhesive, which stays flexible over time. Make sure the blocks are dry before applying the adhesive. Overhang the capstones about 1 to 1-1/2 inch. Joe and Jake use a scrap 2×4 as a guide.

Reducing soil erosion, turning steep slopes into terraced backdrops, creating focal points in the landscape—retaining walls serve many purposes. Indeed, they are some of the most common ways to correct problems caused by hilly areas! Well-built retaining walls transform unworkable inclines into usable outdoor space for the garden. Despite their simple appearance, though, these walls require a good deal of planning—sometimes professional engineering—to keep their shape. Soil is heavy, especially when soaking wet from a recent rainstorm, so a basic retaining wall (four feet tall and 15 feet long) potentially has to support up to 20 tons of soil pressure. With every additional foot of height, the pressure of the soil increases substantially. Miscalculate your construction plans, and you could end up with a weak wall that risks bulging or, worse, collapsing altogether. For just this reason, retaining walls taller than four feet should be designed and constructed by the pros.

Designing very tall walls gets rather complex when accounting for lateral pressure, as do the reinforcement options. For example, a retaining wall 8 feet tall is not just twice as strong as a wall 4-foot tall. The 8-foot wall actually needs to be four times stronger. For walls taller than 4 feet, hiring a licensed engineer to develop a design would be a smart move. At the very least, remember to follow the system manufacturer’s instructions to the letter. Plus, keep in mind that building big walls means moving truckloads of soil, gravel and heavy block. Find even more information at Best Retaining Walls Colorado.

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.
