Find out MoreWhy Retaining Walls Are Important in Arnold, Missouri
Arnold sits within Jefferson County and shares the typical Missouri clay soil conditions found across the St. Louis region. Clay soil absorbs water during rainfall and expands. When it dries, it contracts. This soil movement creates pressure against slopes and landscaping structures.
Without proper slope stabilization and drainage planning, soil movement can lead to landscape damage or water accumulation around structures.
A professionally built retaining wall helps:
Support slopes and elevated landscapes
Control soil movement
Improve soil erosion control
Manage water drainage
Create usable outdoor space
Many Arnold homes are built on gradual hillsides near the Meramec River basin. These properties benefit significantly from engineered retaining wall systems designed to manage soil pressure and water flow.

We provide full-service retaining wall construction tailored to the terrain and soil conditions found in Arnold, Missouri.
Concrete Retaining Wall Installation
A concrete retaining wall is commonly used where structural strength is required. Poured concrete walls are designed to handle higher soil loads and are often used for larger landscaping projects or structural slope support.
Concrete walls can also be integrated with patios, driveways, and foundation support systems.
Block Retaining Wall Installation
A block retaining wall uses interlocking retaining wall blocks designed for structural landscaping applications. These systems are commonly used in residential projects because they provide reliable structural performance and controlled drainage.
Segmental block systems also allow flexibility for curved or tiered landscape designs.
Segmental Retaining Wall Systems
A segmental retaining wall uses engineered block units that lock together without mortar. These systems distribute soil pressure efficiently and are widely used in modern landscaping projects.
Segmental walls are commonly used for:
Garden terraces
Yard leveling
Patio support walls
Property boundary landscaping
Landscape Hardscaping Retaining Walls
Retaining walls are often integrated into landscape hardscaping designs. They can support outdoor living spaces such as patios, walkways, seating walls, and garden areas.
These installations combine structural support with functional landscape design.
