Limestone retaining wall repair firm 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.

If the wall runs up a hill, continue each base course into the hill until the top of the second course is level with the grade, and then start your second base course at that point. If you have the option, it can be easier to excavate and lay the lowest course before excavating the trench for the next step, especially if you have to step up several times. Save yourself some money and install the cheapest style/color that matches the wall style (usually the gray ones) on the bottom course since it won’t be seen.

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.

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.
