Ledgestone retaining wall building tips

Limestone retaining wall repair advices: 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.

Ensure you order everything you need at once and set aside an allowance for breakages and cutting. Contrary to popular belief, building a fence on top or behind a Block Retaining wall is rather easy. In some cases where only a small amount of retaining is required as in 200-400mm, the fence can be built directly on top of the wall with the fence posts passing through the walling blocks and concreted into the ground as normal. This method would be ok to use with all forms of fencing such as post and rail, colour bond post and rail, good neighbour fencing, tubular panel and even pool fencing.

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.

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.

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.
