What do you put under retaining wall blocks?
Use crushed gravel to fill in the back and sides of your blocks. Backfill helps with water drainage. Compact the backfill before starting on the next row of blocks. You should clean and sweep the top of each row before placing the next one.
How can I make my retaining wall look nice?
A brightly colored flower bed will distract from the wall itself, so it’s a good way to freshen up the look of your landscape without having to replace your existing retaining wall. Trailing plants would also be useful to use as they will cascade down over the wall, creating a romantic look.
What do you put behind a retaining wall?
Backfill refers to the dirt behind the wall. In order to provide proper drainage, at least 12 inches of granular backfill (gravel or a similar aggregate) should be installed directly behind the wall. Compacted native soil can be used to backfill the rest of the space behind the wall.
Should retaining wall blocks be glued?
Retaining wall blocks typically do not need adhesive to lay each course. If you wish to lay more than two courses, you only need to cut a block in half for the even-numbered courses.
How deep should a base be for a retaining wall?
The general rule of thumb is to bury about one-eighth of the height of the wall. For example, if your wall will be three feet (36 inches) tall, the first course of blocks should start five inches below soil level. The gravel base should start three inches below this.
Can you lay block on dirt?
Cinder blocks are sometimes set in cement but you can also place them directly into the soil. They are solid and heavy enough to hold down weeds and resist shifting.
How do you stack retaining wall blocks with lips?
Push the retaining wall block back so the lip hangs below the first retaining wall block row’s surface. Pull the block forward until the lip butts up tightly against the first row’s backside. Lay a second block next to the first block and position its lip tightly against the first row’s backside.

Should a retaining wall have drainage?
Retaining wall drainage is critical. It ensures water does not collect behind the wall, causing it to fail. A quality drainage system collects and redirects rainwater away from the wall. It decreases pressure on the soil around the foundation and within the wall itself, reducing erosion and settlement.
