Limestone retaining wall repair in Colorado

Limestone retaining wall repair tricks: How wide should a retaining wall trench be? The trench you are going to build your retaining wall in should be wide, deep, and level. Size the trench so there’s enough room for the block and at least 8 inches of space behind it. Excavate deep enough to completely bury at least one full course, including space for 6 to 8 inches of base material. Establish a level trench to ensure an even layer of base material. That will help prevent the wall from tipping after freeze/thaw cycles. Our experts use a laser level and a story pole to determine the depth of the trench.

If the block Retaining wall is more substantial as in a metre high or more then the fence would have to be behind the wall instead of through or on top. Most Segmental Retaining Wall blocks do not have a big enough cavity or void for the fence post to be directly concreted inside them and would lack the strength to hold the weight of a fence. Generally, most walls are built using an aggregate (Gravel) backfill or in some circumstances No Fines Concrete (NFC). Because of this, an allowance has to be made for the fence post at the early construction stage such as installing PVC Piping as a sleave for the fence post to fit into, this would require some forethought and good planning.

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.

DO start with a good foundation. Your retaining wall will only be as strong its support system. For a stacked-block retaining wall that’s no higher than four feet, a trench filled with three inches of crushed rock will help keep the wall from shifting and settling. The exact depth of the trench depends on the proposed height of the wall, but follow this rule of thumb: Dig a trench to be an eighth of the wall plus three inches. For example, if you want the finished height of your retaining wall to be three feet (36 inches) tall, you’d need to dig the trench eight inches deep to accommodate three inches of crushed rock and about five inches (or an eighth of the visible retaining wall) to start the wall below grade.
