What Type Of Retaining Wall Should I have Installed?
At Gramm Outdoor Contracting, we specialize in designing and installing durable, functional, and visually appealing retaining walls that enhance both residential and commercial landscapes.
Retaining walls are essential for preventing soil erosion, managing slopes, and creating level spaces for outdoor living. Below, we’ll explore the different types of retaining walls available and their benefits.
Types of Retaining Walls
Gravity Retaining Walls
How They Work:
Gravity retaining walls work by relying on their own weight to resist soil pressure and maintain stability. These walls are often built with heavy materials like stone, concrete, or brick to provide the necessary mass. They are often called dry stack retaining walls because no mortar is used to hold the blocks together.
Benefits:
- Simple construction with minimal reinforcement
- It can be built using natural stone for an aesthetically pleasing look
- Ideal for shorter walls under 4 feet
Anchored Retaining Walls
How They Work:
Anchored retaining walls use cables or rods driven deep into the soil and secured with anchors to provide additional stability. These walls are beneficial in areas where space is limited or where heavy loads must be retained.
Benefits:
- Ideal for steep slopes and high walls
- Provides strong reinforcement for areas with high lateral pressure
- Can be used with various facing materials for a customized look
Cantilevered Retaining Walls
How They Work:
Cantilevered retaining walls feature a base slab and a thin vertical stem that work together to leverage the weight of the backfilled soil. Typically constructed from reinforced concrete, these walls can support significant loads.
Benefits:
- Requires less material than gravity walls, making them cost-effective
- Suitable for medium to large-scale projects
- Long-lasting structural integrity
Sheet Pile Retaining Walls
How They Work:
Sheet pile retaining walls consist of long, thin sections of steel, vinyl, or wood driven deep into the ground. They are commonly used in soft soils or waterfront areas.
Benefits:
- Efficient for space-constrained areas
- Ideal for temporary or permanent structures
- It can be installed quickly with minimal excavation
