Steps to build concrete retaining walls
- Mark out the area
The first step is to mark out the area where you want to build the concrete retaining walls. Also, find out if they are any underground wire.
In some cases, cable wires or telephone wires are buried underneath the surface level of the ground.
- Dig and level the base
Proceed to dig and level the surface where the concrete retaining wall will be built. To do this, use transit to make a smooth and level height.
Then go on to build a deep flat space of 4-6 feet and a width of about 24-28 feet. It let you build the allowed base material.
Give a clear space of a minimum of 12 feet at the back of the wall to build the crushed rock.
Put in about 4-6 feet of sand or material level to the upper part of the stakes. Also, reduce it until you are sure it is 1 foot underneath the top. You can use a tamper for this.
- Pour sand into space and screed it
Give a smooth sand base for building the initial part of the blocks. Use a flat screed board to make the sand level.
Also, use a hand trowel to remove bumps if they are any.
- Make the initial row level
Use a tau sting line to make a level row after installing the first part of the blocks. Then add natural soil to straighten the level on both sides.
- Hit pins to close the parts one after the other
This will enable you to achieve the ¾ backset for every row. An additional pin is needed to put the installed pins under the block surface so it won’t disturb the blocks on the subsequent rows. Then cut the blocks with a chisel.
- Backfill with crumpled and unbalanced gravel
Crushed gravel helps in providing a channel for water to pass through. It would also help in leading the backfill pressure downward and not outward.
- Use unique cap blocks
Cap blocks can be placed with a slender overhang. The cap blocks end the concrete retaining walls. It also makes the top of the walls lovely.
