Professional Retaining Walls in Oakland County, MI

Retaining walls in Oakland County cost between $25 and $75 per square face foot installed, with most residential projects ranging from $3,000 to $30,000. Higher Ground Landscaping builds engineered retaining walls using natural stone, boulders, and segmental block systems that solve erosion problems, create usable tiered spaces, and add dramatic visual impact to your property.

Oakland County's rolling terrain creates constant challenges with erosion, unusable slopes, and water runoff. A properly engineered retaining wall transforms a steep, eroding hillside into usable flat space for a patio, garden, or lawn area. Retaining walls also prevent soil from washing into driveways, burying walkways, or undermining foundations during heavy Michigan rainstorms.

Tony Barash has engineered and built retaining walls of every size and material across Oakland County since 1996. Every wall we build includes proper drainage behind the wall face, a compacted gravel base below the first course, and geogrid reinforcement for walls over 3 feet tall. These structural elements separate a wall that lasts 30 years from one that leans and fails within 5.

Wall Types

Retaining Wall Options

Natural Stone Retaining Walls

Natural stone walls offer timeless beauty and blend seamlessly with the landscape. We build dry-stacked and mortared walls using Michigan fieldstone, Pennsylvania bluestone, and other natural materials. Natural stone walls cost $40 to $75 per square face foot and are ideal for garden terraces, patio borders, and decorative applications up to 4 feet tall.

Boulder Retaining Walls

Boulder walls use large natural stones (500 to 3,000+ pounds each) stacked and set with an excavator to create a rugged, natural look. They are extremely durable and require minimal maintenance. Costs range from $25 to $50 per square face foot depending on boulder size and access.

Segmental Block Walls

Manufactured segmental block systems (Unilock, Belgard, Versa-Lok) provide clean lines, consistent color, and engineered interlocking for maximum structural performance. Block walls are the best choice for straight walls and 90-degree corners. Costs range from $25 to $45 per square face foot installed.

Terraced Garden Walls

Instead of one tall wall, terracing breaks a slope into multiple shorter walls with flat planting areas between them. Terracing is often more attractive, allows for integrated landscaping, and may avoid the need for engineered plans required for walls over 4 feet. Terraced walls add far more visual interest and usable planting space.

Erosion Control Solutions

Not every slope needs a retaining wall. We also install rip-rap channels, geotextile slope reinforcement, native plant stabilization, and French drain systems that redirect water before it causes erosion. Sometimes the most effective solution combines a small retaining wall with drainage improvements and strategic plantings.

Wall Drainage Integration

The number one reason retaining walls fail is water pressure building up behind them. Every wall we build includes a perforated drain pipe at the base, 12 or more inches of clean gravel backfill behind the face, and weep holes at regular intervals. In Oakland County's clay soil, this drainage layer is absolutely critical.

Engineering

What Makes a Retaining Wall Last

Compacted Gravel Base

Every wall starts with excavation to undisturbed soil, then 6 to 8 inches of compacted gravel. The first course is set below grade to anchor the wall. Without this foundation, walls settle unevenly within a few freeze-thaw cycles.

Geogrid Reinforcement

Walls over 3 feet require geogrid -- a woven polymer mesh extending into the retained soil. Geogrid turns the wall and soil into a single reinforced mass that resists lateral pressure of wet clay soil. We install geogrid at every other course.

Drainage Behind the Wall

We install 4-inch perforated pipe at the base of every wall, surrounded by clean washed gravel, with outlet points at both ends. The gravel zone extends 12 inches behind the wall face separated by geotextile fabric. This prevents hydrostatic pressure that pushes walls over.

Common Questions

Retaining Wall FAQ

How much does a retaining wall cost in Michigan?

Retaining walls cost $25 to $75 per square face foot installed. A small garden wall (2 feet tall, 20 feet long) costs $1,500 to $3,000. A large structural wall (4 feet tall, 50 feet long) costs $10,000 to $30,000.

Do I need a permit for a retaining wall in Oakland County?

In most Oakland County municipalities, walls over 4 feet tall require a building permit and may need engineered plans. Walls under 4 feet typically do not require permits. Higher Ground handles the permit process.

How long does a retaining wall last in Michigan?

A properly built wall with correct drainage lasts 30 to 50 years or more. The most common cause of failure is inadequate drainage behind the wall, which allows water pressure to build up and push the wall outward.

What is the best material for a retaining wall in Michigan?

Segmental block offers the best structural performance. Natural stone provides the most character. Boulders are the most rugged and low-maintenance. Tony recommends the right material for each site during the free consultation.

Why Higher Ground

Structural Experts Since 1996

Tony Barash has built hundreds of retaining walls across Oakland County, from small garden borders to massive structural walls holding back hillsides. He understands the engineering behind why walls succeed or fail -- and the most common failure point is always drainage. That is why every wall we build includes a complete drainage system as a standard part of every installation.

We take on projects that other contractors avoid. Steep slopes, limited access, clay soil conditions, proximity to foundations and utilities -- these are the challenges we solve every day. Tony personally evaluates every site and designs the wall system specific to your property's conditions.
