Retaining Wall for Home Improvement and Types of It

Constructing a retaining wall for landscape improvement can be a fun project, especially when it is related to the nearby areas or in own land. Soil erosion comes first when it is about preserving the land because wearing away the topsoil can collapse a massive land. Retaining walls can hold the soils in their places and resist the further movement of the land. In many places, a retaining wall is used to manage the destructive force of raindrops and stormwater.

When it is about constructing the wall, you must know about the types of wall that need to be built in your place. There are several types of retaining walls that can be constructed, and here, we will highlight some of the most common walls to build on the lawn or in a sloppy land.

Types of Retaining Wall

  • Gravity retaining wall

These walls are massive in size, and they are called gravity walls because they stand on their weight to resist the enormous force of the land. While building this wall, the owner has to focus on the load and the base. Forces like sliding, overturning, or bearing must be taken into consideration during the designing process. Heavy materials like stones, concrete blocks, or bricks are used to construct this wall.

  • Cantilever retaining wall

These walls are constructed by using concrete, and most importantly, this wall needs to be reinforced to provide strength against the pressure. There are two sections of this wall – stem and slab. The slab is further divided into two parts – heel slab and toe slab. The heel section is located at the backfilling side, while the toe is located at the opposite. Compared to the gravity walls, these walls require much less concrete, but you have to be technical and design precisely to construct them.

  • Counterfort retaining wall

These walls are similar to the cantilever retaining walls because of those three similar sections – stem, heel slab, and toe slab. But the difference appears when it is about the support. Counterfort retaining wall is reinforced with special counterforts, which are made of concrete structures that connect the top of the stem with the toe slab. This shape reduces the possible bending tendency of the wall and supplies secondary force, which increases the strength of this wall to withstand additional pressure.

  • Mechanically stabilized earth walls

These are the most common retaining walls and are constructed on risky sites. These structures include a reinforcement element and a facing element embedded in the soil behind the wall (backfilling materials). Elements like concrete or segmental blocks, steel wire, etc. are used to made facing elements, while geosynthetic or metallic compounds are used to construct the reinforcing element. This wall is built to prevent the landslide or to support a huge landmass.

  • Anchored retaining wall

Cable rods or wires are used to construct and reinforce this wall. Those cables are driven deeper into the soil, and after that, the ends of them are filled with solid materials like concrete. Because of this, the wall is called the anchored wall.

These are the most popular types of retaining wall that anyone can build on his land either to enhance the beauty or to protect the land from being eroded.
