Retaining Wall Blocks Cost

What Are Retaining Walls Used For?

retaining-wallIf your property has uneven terrain,  you’ve probably considered a retaining wall.

Retaining walls serve many purposes for both residential and commercial applications.

But essentially, a retaining wall is built to hold back soil and ensure it remains in place.

However, retaining walls can be built to increase the usable space, as a feature or visual interest to enhance the overall look of your property, for added privacy, or simply to reduce erosion over time.

What Are The Different Types of Retaining Walls?

In masonry, there are 3 types of retaining walls.

Gravity retaining wall

A gravity retaining walls use the mass of the blocks to retain the earth and to prevent sliding, sheer, and overturning.

Inclined retaining wall

Inclined retaining walls act much the same as gravity retaining walls, except for the fact that the incline actually improves its performance and a little less mass can be used.

Reinforced block retaining wall

This is often considered to be the best performing retaining wall that also requires fewer materials to construct it. Reinforced block retaining walls use the cantilever of the foundation raft that is connected to the wall.

What’s the best material for retaining walls?

  • concrete
  • stone
  • wood
  • brick
  • plastic lumber

Characteristics to Consider

The whole idea of a retaining wall can be confusing to some, and most homeowners simply want them to be as beautiful as they are functional.

However, without some professional advice, it can be difficult to decide what type of materials to choose from. Someone trying to even out the property will have vastly different needs than someone interested in building a flower bed.

For starters, the size and height of the wall must be considered. Smaller retaining walls can be completed as a DIY project over the weekend, but doing excavation work will require a professional contractor.

Retaining walls also need proper drainage. Poor workmanship and incorrect materials choice almost always leads to moisture-related problems. This may require different types of soil fill and even an engineered drainage system, so a local expert’s input may be required.

Different materials also provide different aesthetics while different finishes will provide different effects. Some homeowners will opt for simulated stone veneer, while stucco or simple and natural color variations remain popular choices.
