Limestone retaining wall repair tricks: 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.
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.
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. Please read our reviews and look and our photo gallery. See more details at Colorado Retaining Wall Builder.
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.
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.
