The Way to Construct a Retaining Wall With Dry Blocks

Retaining wall blocks come in a variety of shapes and sizes to fit any need. Building a wall takes some preparation. Due to the burden of the earth behind the wall, many municipalities require an engineer design any wall . In the majority of municipalities, you should have before you begin the project, a building permit.

Concrete Masonry Units

Concrete masonry units, or CMUs, would be the building blocks used in a multitude of building jobs. The conventional blocks are available in various colours and have a variety of faces available. The weight of the blocks lets you place them. Capstones and shorter blocks will also be available so you can complete a wall together. Many CMUs have openings within their centers. Through the openings from the blocks, push pieces of reinforced rebar, at two, or pub – to 3-foot intervals for wall stability and to the base of this wall.

Additional Retaining Wall Blocks

Other types of retaining wall sockets are available at landscape supply stores and home centers. Some of those blocks have a connector on their back that enables them to interlock with the blocks placed over them. This provides additional stability to a sterile block wall without the need for reinforcement. Some blocks need further reinforcement’s use, such as rebar.

Base of this Wall

The base of this wall is as important to a wall that is stable as the blocks used to make it. Start by digging a trench approximately 7 to 8 inches deep and at least 12 inches wider than the diameter of the CMUs you’re using. Fill the trench with small, crushed gravel and level it. Top the crushed gravel with a bed. You need to be able to walk on it without disturbing the sand, once you compact the base of this trench with a hand .

Building the Wall

The base row of blocks is set side by side. Once it is set up, check that all the blocks are level from front to back and side to side. Insert the row, beginning with a half block. If half-blocks aren’t available from the style you’re currently using, score a line on each side of a block with chisel and a hammer. Set the sharp edge of the chisel along the middle of the line that was . Rap at the conclusion of this chisel firmly with the hammer to split the block in two. Finish the row with a different half block. Continue setting the blocks until the wall is the height. As you put in each row of blocks, fill with stone tamped into place in the region behind the wall. So you are able to replant grass when you reach the top of the wall, fill with topsoil in the 5 to 6 inches or put in a flowerbed. Capstones held with masonry glue in position are one method. Not only do they prevent water but capstones provide you with a place to sit down on the wall that is finished.
