Do you need landscape fabric behind the retaining wall?

Oct 9


The best way to hold soil in place is with retaining walls. This allows people to use the space adjacent to the wall and then plant plants on top of it. For durability and long-term success, this requires solid foundations and proper construction.


It is recommended that landscape fabric be used to strengthen retaining walls. It acts as a barrier against soil entering the wall's small holes and keeps weeds away from its exterior surface. The fabric enhances the wall's durability.


This article will explain the importance and layout of landscape fabric for a retaining wall. We'll also discuss the types of retaining walls available and how to avoid three common failures.

Are Landscape Fabrics Required Behind a Retaining wall?

To maintain the wall's shape and durability, landscape fabric should be used behind a retainer wall. The material is a barrier to keep the soil and soil from getting into the walls. This prevents dirt and weeds from getting into the holes in the future.


Landscape fabric is a crucial component in controlling weeds. It is made from woven fabric, and some varieties have ultraviolet protection to prolong the fabric's life. It doesn't matter if you plan to use bricks or wood to build your wall; landscape fabric should be placed behind your retaining walls.


Landscape fabric can be placed behind a wall to help retain soil. Retaining walls are designed to preserve the form of garden landscapes and structures. Landscape fabric is a way to help the retaining walls maintain their shape and grow over time.


Because soil can get into the walls through the openings, landscape fabric will prevent 

  1. This is because the ground could cause weed growth. If the soil is not kept clean, it can cause the wall's construction to fall apart.

How to lay landscape fabric behind a retaining wall

Digging a trench is the first step to laying landscaping fabric behind your retaining wall. The track should be filled with fabric. Next, add soil and gravel to the trench. Clear the area by removing any soil, objects or materials used during work.

Prepare a shovel and rake before you begin the entire process. To prevent walls from falling, you should not use too much force when digging or backfilling.

Look behind the wall.

You must first dig the trench to lay the landscaping fabric behind your retaining wall. Dig a 6--8-inch trench until you reach the bottom of the wall. To prevent the wall from collapsing, be careful when digging.

Place the landscaping fabric.

The landscaping fabric should be pushed down to the trench you have just dug. After you have placed the material, place the top part of it on top. To hold the fabric in place, you can use a heavy object to support it.


Repeat the process until all areas behind the wall have been covered in landscaping fabric. You will need to do this again, as landscaping fabric may have a different width than the entire width. The material can be attached to the wall with construction adhesive.

Fill the trench with water.

After you have covered the back of the retaining walls, you can fill the trench with gravel. To avoid over-pressure on the walls, backfill the hole slowly to prevent it from collapsing. The wall is already built with soil supporting its back. If you force it to backfill, it could cause movement in the bricks.


Fill the trench with soil at least 2 inches apart. You will fill the space with the ground that you have dug. To flatten and smooth the gravel's top, don't forget to level it.

Fill in the rest

The next step is to fill the space with soil. This is the 2-inch space you left in the trench after you filled it with gravel. To fully cover the track and gravel, you can add an inch.

Smoothen the soil by pushing a little to compress it. To avoid damaging the walls, press gently. Continue this process until the earth is the same height as the ground behind the retaining walls.

Clear the area

Clear the area by removing any objects used to support the landscaping fabric. Now that you have buried the material in soil and gravel, you can trim the excess fabric to fit the retaining wall. You can also remove any dirt you don't use while filling the trench.



A great way to keep soil from getting in the way is by retaining walls. It is essential to use proper construction to ensure its durability and shape for a long time. Landscape fabric can be used to improve the wall's structure. While some materials can ensure your wall's durability, it is susceptible to being blown down by the climate. When building retaining walls, it is essential to consider these factors.


Even if the wall is damaged, it is vital to maintain its strength. It is essential to keep the structure intact and avoid accidents due to the wall's collapse. It is necessary to repair retaining walls Pittsburgh as soon as they are damaged. This will prevent any further accidents or damages. You do not want to find yourself in this situation.
