Concrete Footings & Retaining Walls
Engineered structural support and erosion control solutions that protect your property and provide stable foundations for Council Bluffs construction projects.
Expert Footing and Retaining Wall Construction
Footings and retaining walls are critical structural elements that provide stability, prevent erosion, and create usable space on sloped properties. At GravEdge Council Bluffs Concrete, we specialize in designing and constructing engineered concrete footings and retaining walls that meet structural requirements while enhancing your property's functionality and appearance.
Our team has extensive experience working with Council Bluffs' varied terrain and soil conditions. We understand the engineering principles required to create stable, long-lasting structures that resist soil pressure, manage water drainage, and maintain their integrity through Iowa's freeze-thaw cycles. Whether you need footings for a new structure or a retaining wall to manage a slope, we deliver solutions built to last.
Professional Concrete Footing Installation
Footings are the foundation beneath your foundation, distributing structural loads to the soil below. Properly designed and installed footings are essential for any structure's stability and longevity:
- •Building Footings: Load-bearing footings for homes, garages, and commercial structures
- •Column and Pier Footings: Isolated footings for posts, columns, and support piers
- •Wall Footings: Continuous footings for foundation walls and retaining structures
- •Frost Footings: Deep footings that extend below frost line to prevent heaving
- •Equipment Pads: Reinforced concrete pads for HVAC units, generators, and heavy equipment
Custom Retaining Wall Design and Construction
Retaining walls serve both functional and aesthetic purposes, holding back soil to create level areas while preventing erosion and managing water runoff. We design retaining walls that are engineered for your specific site conditions, considering soil type, slope angle, drainage requirements, and the height of the wall.
Our retaining wall solutions include poured concrete walls for maximum strength, concrete block walls that offer design flexibility and easier installation, and decorative options that enhance your landscape. Every retaining wall we build includes proper drainage systems to prevent water buildup behind the wall, which is the leading cause of retaining wall failure. We also ensure adequate reinforcement and proper backfill materials for long-term stability.
Engineering Principles and Drainage Management
Successful footings and retaining walls require proper engineering to resist the forces acting upon them. For footings, this means calculating the required size and depth based on soil bearing capacity and structural loads. We ensure footings extend below the frost line (typically 42 inches in Iowa) to prevent frost heaving that can damage structures.
Retaining walls must resist lateral soil pressure, which increases with wall height and soil moisture content. We incorporate drainage systems including weep holes, drainage pipes, and gravel backfill to manage water and reduce pressure on the wall. Proper compaction of backfill material and installation of geotextile fabric further enhance wall stability. For complete foundation solutions, explore our foundations and slabs services.
Applications and Benefits of Retaining Walls
Retaining walls solve numerous property challenges while adding value and usability. They can create level areas for patios, gardens, or play spaces on sloped lots. They prevent soil erosion on hillsides and protect structures from sliding soil. Retaining walls can also define property boundaries, create raised planting beds, and add visual interest to your landscape design.
For properties with drainage issues, retaining walls can be integrated with comprehensive drainage solutions to direct water away from structures and prevent flooding. We can design terraced retaining wall systems for steep slopes, creating multiple level areas that are both functional and attractive.

Frequently Asked Questions
How deep do footings need to be in Iowa?
Footings in Iowa must extend below the frost line, which is typically 42 inches deep. This prevents frost heaving that occurs when frozen ground expands and lifts the footing. We ensure all footings meet or exceed local building code requirements for depth and width based on your structure's load requirements.
Do I need a permit for a retaining wall?
Permit requirements vary by municipality and wall height. Many jurisdictions require permits for walls over 4 feet tall or walls supporting significant loads. We're familiar with local building codes and can help you navigate the permit process. It's always best to check with your local building department before starting construction.
How tall can a concrete retaining wall be?
Concrete retaining walls can be built to considerable heights with proper engineering. Walls under 4 feet often don't require engineering, while taller walls need professional engineering to ensure adequate strength and drainage. We work with engineers on walls requiring structural design and can build retaining walls of virtually any height needed for your property.
What causes retaining walls to fail?
The most common cause of retaining wall failure is poor drainage, which allows water to build up behind the wall creating excessive pressure. Other causes include inadequate footing, improper backfill, lack of reinforcement, and failure to consider soil type. We prevent failures by incorporating proper drainage systems, engineered design, and quality construction techniques.
How long do concrete retaining walls last?
Properly constructed concrete retaining walls can last 50-100 years or more. Longevity depends on quality of construction, drainage systems, soil conditions, and maintenance. Our walls are built to engineering standards with proper drainage, ensuring they provide decades of reliable service protecting your property.
