Lake Quivira Outdoor Lighting

Today we are talking about building a retaining wall in Lake Quivira. The blocks for this project have a locking flange, which makes the installation easy, and they can be used to build walls up to 28 inches high.

It's smart to plan your layout. Avoid having downspouts pointed at the wall, and if it's against the house, keep the soil bed well below the siding. To mark a freeform layout, use a piece of rope or hose to outline the shape, then use a shovel to outline. For straight lines, mark the entire bed area with stakes and string. You can use marking paint to make curved corners. Do this by tying a string to a stake that's equidistant to the edges. Creating a compass and spraying the curves with marking paint.

To determine how many blocks you'll need per row, divide the wall's total length by the length of the block. To see how many rows you'll need to divide the ideal wall height by the height of the block. Don’t forget to account for the 1st row to be half-buried.

With the layout marked, you can begin digging the trench. To bury the first row about halfway, dig the trench about four to six inches deep and dig 12 inches wide or twice the block's width. If the trench slopes, you'll have to step up or down to keep the blocks level. Tamp down the dirt with a hand tamper and keep it level. Next, fill the trench with about 3 inches of paver base, spread it with a rake, and tamp it down. Tamping the base provides a strong foundation when it's all level, you can begin installing the blocks.

For row, one knock off the flange with a hammer and chisel so the blocks will sit flat. Beginning at the end with the lowest elevation, set the first block in place and check for level. Then place the next block making sure it's even with the first. Continue installing the first row, periodically checking for level. Fill in under low blocks with a paver base or tap down high blocks with a rubber mallet.

After installing each row, sweep the dirt off the tops to start the second row. You'll have to cut a block to stagger the joints. Mark it and cut it with a masonry blade. Put it in place, keeping the flange tight against the first row check it for level. When installing the next few rows, you'll need to add drainage directly behind the blocks.

Lay down landscape fabric behind the wall leaving enough excess to reach the top. Then fill in directly behind the wall with gravel as you continue to build. For the last two rows of full blocks, apply concrete adhesive to the wall then set the blocks in place.

Now just fold the excess fabric back and fill in with soil and plants. A plain garden bed gets a brand new personality with the help of a block retaining wall. Want more great ideas and help with your hardscapes in Leawood. Give Landscape Lighting of Lenexa a call at 913-359-8704.
