Ledgestone retaining wall building in Colorado: 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.
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.
While you’re at it, do also place a call DigSafe (811), a nationwide service that will notify local utility companies that you plan to dig. These can determine whether their buried lines will be in the way and mark their exact locations. Retaining walls can be constructed using a variety of materials, from poured concrete and large timbers to natural stones, even bricks. For DIY purposes, opt for manufactured blocks that are designed specifically for building retaining walls; a locking flange along the bottom edge creates a secure attachment between rows. These blocks (available in gray and earthy tones in smooth or textured faces, like these at The Home Depot) can be found at virtually any home improvement store and many garden centers as well.
Perhaps not as builder-friendly for the first-time DIY’er, a concrete retaining wall can nevertheless provide maximum protection for any property against drainage and erosion problems. According to the experts at Quikrete, unlike brick and stone, walls built with concrete do not require additional reinforcement because the width of the base and the weight of the wall provide adequate structural support. The most important step in constructing a strong, attractive concrete wall is building a sturdy, accurate form. Wall forms must be strong enough to withstand the great pressure exerted by the wet concrete; any failure in the forms will be disastrous. A straight wall form is constructed of 1/2-inch, 5/8-inch or 3/4-inch exterior grade plywood sheathing, studs, spacers, ties and walls. Sheathing forms the mold, while studs back up and support the sheathing. Find extra information at Best Retaining Walls Colorado.
