How to Stack Retaining Wall Blocks With Lip
To stack retaining wall blocks with a lip, you should first prepare the trench and measure its length, as well as the length of the block.
Divide the trench’s length by the block’s length to determine the number of blocks needed.
Then, flip the number of blocks determined upside down, removing the lip from each block using a chisel blade.
Lay the first row of blocks in the trench with the side that used to have the lip facing down.
For the second row and above, place each block with the lip hanging below the surface, pushing it back until the lip butts up against the backside of the previous row.
Repeat this process for subsequent rows.
It is important to build the wall during dry weather conditions and consider any necessary permits or zoning restrictions.

Did You Know?
1. The concept of retaining walls dates back to ancient civilizations, with some of the earliest examples found in ancient Greece and Rome. These civilizations used various materials such as stone, brick, and wood to construct these walls, showcasing early engineering prowess.
2. One fascinating fact about retaining walls with a lip is that the lip itself plays a crucial role in maintaining stability. The lip acts as a locking mechanism, preventing the blocks from shifting or sliding out of place over time due to the weight and pressure exerted by the soil and backfill.
3. Retaining wall blocks with a lip, also known as interlocking blocks, were first patented in 1948 by the German engineer Franz Schnell. His patented design aimed to create a more efficient and stable method of constructing retaining walls.
4. Building upon the previous point, the interlocking design of retaining wall blocks with a lip has significantly simplified the construction process. These blocks can be stacked and secured without the need for mortar, making it much easier for DIYers and homeowners to create their own retaining walls.
5. The lip on retaining wall blocks not only enhances stability but also allows for better water drainage. By creating a recessed cavity behind the lip, excess water is directed away from the wall and instead percolates through the backfill, preventing any potential damage caused by hydrostatic pressure.
Preparing The Retaining Wall Trench And Measuring Its Length
Before starting the process of stacking retaining wall blocks with a lip, it is essential to prepare the retaining wall trench and measure its length. The trench is the foundation of the wall and needs to be dug out to the appropriate depth and width. This will ensure stability and durability for the retaining wall.
To prepare the retaining wall trench, start by marking the area where the wall will be placed. Use stakes and strings to outline the desired shape and length of the wall. Once the area is marked, begin digging the trench, making sure to remove any debris or vegetation that may interfere with the proper placement of the blocks.
After the trench is prepared, take accurate measurements of its length using a measuring tape or a measuring wheel. Additionally, measure the length of a single retaining wall block. By dividing the trench’s length by the block’s length, you will be able to determine the number of blocks required to complete the wall.

Removing The Lip From Each Retaining Wall Block
Once the number of blocks needed for the retaining wall has been determined, the next step is to flip the blocks upside down so that the lips point up. This is done to facilitate the leveling process of the first row of blocks.
To remove the lip from each block, you will need a chisel blade. Carefully position the chisel at the base of the lip and strike it with a hammer. Apply consistent pressure to remove the lip completely. Take your time during this step to ensure that the removal is clean and the surface is even.
Removing the lip from each retaining wall block will make it easier to lay the first row and achieve a level foundation. This step is crucial for the stability and integrity of the entire retaining wall structure. Take caution while using the chisel blade to avoid any injuries and wear protective goggles to shield your eyes from flying debris.
Laying The First Row Of Retaining Wall Blocks
With the lips of the blocks removed, it’s time to lay the first row of retaining wall blocks in the prepared trench. Start by placing the blocks with the side that used to have the lip facing down on the ground. This will create a stable base for the rest of the wall.
Ensure that the blocks are aligned properly and tightly fitted together. Use a level to check the horizontal and vertical alignment of each block. Adjust the position of the blocks if necessary, making sure that they are level and straight along the entire row.
Prioritize the leveling process during this stage, as any discrepancies in the first row will affect the stability and appearance of the entire structure. Take your time to achieve a precise and level foundation, as this will make the stacking process easier in the subsequent rows.

Placing The Second Row Of Retaining Wall Blocks With Lips Hanging Below The Surface
After completing the first row, it is time to move on to the second row of retaining wall blocks. Take a block with the lip edge down and place it on top of the first row, ensuring that the lip hangs below the surface.
Position the block in a way that the lip butts up against the backside of the first row. This will create a secure connection between the two rows. Repeat this process with the other blocks in the second row, placing each block tightly against the backside of the block beneath it.
Continue this method of stacking blocks with the lips hanging below the surface for the entire second row. This technique ensures a strong and stable structure by creating interlocking connections between the blocks. Regularly check for levelness and adjust the position of each block as needed.
Continuing To Build The Third And Fourth Rows
To continue building the retaining wall, follow the same principles used for the first and second rows when constructing the third and fourth rows. It is important to ensure tight connections and levelness throughout the stacking process.
When placing each block in the third and fourth rows, make sure the lip of the block is tightly against the backside of the block below it. This will create a strong and dependable wall structure. Continuously check for levelness and adjust the position of each block to maintain a consistent and visually appealing appearance.
As you progress higher with each row, consider the slope steepness and the intended use of the space behind the retaining wall. This assessment will help determine the appropriate height and positioning for each row based on the wall’s purpose and the surrounding landscape.
Considerations And Regulations For Building A Retaining Wall
When constructing a retaining wall, there are several important considerations and regulations to keep in mind:
- Construct the wall when the soil is dry, rather than after a period of rain. Building on wet soil can lead to instability and eventual failure of the retaining wall.
- Check with your local authorities to determine if a building permit is required for your retaining wall. Compliance with regulations is essential.
- Understand zoning restrictions that may dictate factors such as wall proximity to property lines, maximum height, and other conditions. This knowledge will help you plan and construct the wall correctly.
