The Many Types of Precast Concrete Retaining Walls

If you’re unfamiliar with precast concrete retaining walls, you might be unaware of the diverse range of available styles. Building a retaining wall can save time and labor, simplifying construction. In addition, it offers the ability to save space since the concrete is poured and cured off-site.

As you explore the types of retaining walls you can build with precast concrete, you’ll see that you can use them to create a unique and beautiful design for your property. The type of wall you choose will depend on your specific needs, tastes, and budget.

Crib Precast Concrete Retaining Walls

Much like building a log cabin, precast concrete “logs” create the frame of the wall. This process starts with precast concrete logs or posts installed at even intervals along the perimeter of the fence line. A connecting header precast concrete log is then set in place over the tops of the posts.

Once this framework is in place, compacted earth, stone, sand, or gravel forms the wall face. When making a crib wall, you can choose the fill material that best complements your design or suits your needs.

Bin Precast Concrete Retaining Walls

This process involves using interlocking concrete bins to form the wall. Each of the bins interlocks with the others and contains granular soil. Together, the bins and the soil form a gravity barrier that effectively combats soil erosion on your property.

Precast Concrete T-Shape Units

This type of wall uses a T-shape to form the modular blocks that will make up the retaining wall. The horizontal top of the T forms the wall face, while the vertical stem forms the wall’s post. The post is inserted into an excavated hole to form a sturdy support for the wall. This design is ideal for gardens, hills, or other hardscaping needs.

Stacked Bottomless Troughs

Stacked bottomless troughs use a modified crib wall frame. The difference is that the horizontal and vertical logs are poured simultaneously as a single segment. After stacking these components together, the backfill forms the rest of the gravity retaining wall. This is an effective method for building retaining walls on hills or mounds.

Precast Counterfort Walls

These wall systems use triangular counterforts as wall posts — each set at equal intervals. Once set in place, concrete panels are installed between them to form the wall face. Backfill supports the counterforts and panels for added durability and strength.

The design of a precast counterfort retaining wall is quite unique. As a result, it can help you create an attractive yet functional barrier.

Precast Panels with Integral Columns

Each concrete panel has a support column at one end that connects the panels via a tongue-in-groove assembly process. For added support, each column is welded to a cast-in-place pier.

Consider this option when building taller retaining walls on your residential or commercial property.
