Limestone retaining wall construction advices: Block retaining walls are lightweight, cost-effective, and easy to build. They come in a wider range of styles and colours and are more versatile than concrete sleepers, creating curves and tiered walls can be achieved with ease. Block retaining walls have a wide footprint so if your access is tight or room on your property is at a premium then blocks would not be for you.

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.

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. See extra info at Building and repair of retaining walls Colorado.
