Cobblestone retaining wall repair firm in Colorado: 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.
Retaining wall drainage is an incredibly important part of building a stone wall. Once a few rows have been stacked, backfill the wall with rock so it matches the grade height in front of the wall, and then lay down perforated drain tile on top of the rock. Install drain tee fittings and a drain grate every 25 feet to 50 feet, depending on how much rainwater is expected to run down to the wall. Cut one block down to accommodate the drain grate. Screw the drain tile parts together so they won’t come apart when they get covered with more rock. Also, drain the tile to daylight at the ends of the walls whenever possible.
A wall that leans into the soil it retains is less likely to be pushed outward by soil pressure than a plain-old vertical wall. Design and build your retaining wall to slope at a minimum rate of one inch for every one-foot of rise (height). Fortunately, working with retaining wall blocks makes it incredibly easy to achieve this “step-back” construction! The locking flange on the bottom edge of every block guides it to click into position slightly behind the lower block, preventing the top blocks from being pushed outward.
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. Discover additional details at Colorado Retaining Wall Builder.
