Stone retaining wall building provider in Colorado: 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.

First of all, what is No Fines Concrete (NFC)? Basically it is just what the name suggests, concrete without any fine aggregates or sand. It consists of generally an aggregate (gravel), cement and water. The aggregate is coated with the cement slurry binding it together, it dries with the strength of concrete but with voids or air pockets. This makes the NFC light weight and allows water to pass through its honeycomb texture.

We also repair existing retaining walls. Many railroad tie walls or older concrete retaining walls which may or may not include rocks or boulders are beginning to show signs of failure. Often times a homeowner will build a DIY retaining wall that needs help after years of service. 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.

No matter if you choose to build your retaining wall out of block, brick, stone, wood or concrete, the goal should be to integrate the retaining wall into your landscape. The angle of a sloping lawn should never be greater than 45 degrees, and the gentler the slope, the better. The higher the wall, the gentler the slope will be. After determining the wall height, check local building codes. Many municipalities require a building permit and an engineer’s approval before a wall higher than 3 feet can be built. For taller projects, some careful engineering is required to construct a sturdy, long-lasting wall.

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.
