Kingstone retaining wall construction in Colorado: Which retaining wall blocks are best? These solid blocks are heavy. Lighter, hollow blocks are available, but they can’t be split because cutting them will expose the voids. Also, some hollow blocks require individual backfilling, which is time consuming. These pros prefer Versa-Lok blocks, which are held together with pins rather than a lip on the bottom because pinned blocks work better on tighter curves, and the flat bottom makes them easier to stack. They have also found that the small back lip on some lipped blocks can be prone to cracking, which will weaken the wall.

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.

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.

We have the ability to fortify the wall with shotcrete or soil nails which would include helical tie-backs or micropiles.

Good drainage is essential for any retaining wall. Drainage is provided by filling coarse gravel behind the wall and by building weep holes into the wall. Make weep holes by inserting short lengths of 2-inch plastic pipe or 3-inch drain tile in the forms when they are built. The first row should be 2 inches to 4 inches above ground level. If the wall is higher than 4 feet, place a second row of weep holes 3 inches above the first.

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.
