How tall can you build a retaining wall?

We can build retaining walls of any height, but walls over 4 feet typically require engineering and permits. For very tall walls or steep slopes, we may recommend building terraced walls in steps rather than one tall wall. This is often more stable and cost-effective. During our site visit, we assess your slope and recommend the best approach for your situation.

How long does it take to build a retaining wall?

A typical residential retaining wall takes 1 to 2 weeks from start to finish. This includes excavation, building the foundation, constructing the wall, installing drainage, and backfilling. Larger or more complex walls can take longer. If permits and engineering are required, add another 2 to 4 weeks for plan review and approval before construction begins.

How much does a retaining wall cost?

The cost depends on the height, length, type of wall, soil conditions, and finish you choose. Concrete block walls are generally less expensive than poured concrete walls. Walls that require engineering, permits, and heavy equipment cost more than simple garden walls. We provide free estimates after seeing your site and understanding what you need. Your estimate will include all costs so you know exactly what to expect.

Why You Need a Retaining Wall

If your property has slopes, uneven terrain, or drainage issues, a retaining wall can solve those problems. Retaining walls hold back soil to create level areas for lawns, patios, driveways, or gardens. They prevent erosion, manage water runoff, and turn unusable hillsides into functional space.

In Colton and throughout Southern California, many properties sit on sloped lots. Without proper support, heavy rains can wash away soil, undermine foundations, and create dangerous conditions. A well-built retaining wall stabilizes the slope and protects your property from damage.

Retaining walls also add visual interest and define different areas of your landscape. You can use them to create terraced gardens, raised planters, or seating areas. When combined with decorative concrete or natural stone finishes, they become attractive features that enhance your property's appearance and value.

Types of Retaining Walls and Masonry We Build

We build several types of retaining walls and masonry structures depending on your needs, soil conditions, and budget:

•Poured concrete retaining walls: The strongest option for tall walls or heavy loads. These are reinforced with steel and built to last decades.
•Concrete block walls: Built with interlocking concrete blocks that are strong, affordable, and available in various finishes and colors.
•Segmental retaining walls: Modular systems that allow for curved designs and are ideal for landscaping projects.
•Masonry garden walls: Decorative walls using brick or stone that add character to your landscape.
•Freestanding masonry features: Outdoor kitchens, fire pits, planters, and columns built with concrete and stone.

The right type of wall depends on how tall it needs to be, how much soil it will hold back, and what look you want. We assess your site conditions and help you choose the best option for your situation and budget.

Engineering and Installation Process

Building a retaining wall is more complex than it looks. The wall must be strong enough to resist the pressure from thousands of pounds of soil and water behind it. Poor design or construction leads to cracking, leaning, or complete failure.

Site Analysis and Design

We start by evaluating your property. How tall does the wall need to be? What type of soil are we dealing with? Where does water drain? For walls over 4 feet tall or those supporting structures, we work with engineers to design a system that meets code requirements.

Foundation and Drainage

Every retaining wall needs a solid foundation and proper drainage. We excavate below the frost line, pour a concrete footing, and install drainage pipes behind the wall. Without drainage, water pressure builds up and pushes the wall over. We make sure water has somewhere to go.

Building the Wall

For poured concrete walls, we build forms, install steel reinforcement, and pour the concrete in lifts. For block walls, we lay each course level and plumb, filling the cores with concrete and rebar for strength. The wall is built to slope slightly back toward the soil for stability.

Backfilling and Finishing

Once the wall is built, we backfill behind it with gravel for drainage, then top it with soil. The face of the wall can be finished with stucco, stone veneer, or left as exposed concrete depending on your preference. We cap the top for a finished look and to protect the wall from water infiltration.

Permits and Building Codes

Most retaining walls over 3 feet tall require building permits and engineering approval. We handle all the paperwork, submit plans to the city, and coordinate inspections. This ensures your wall is built to code and will not create liability issues if you ever sell your property.

Building codes exist for good reason. They make sure retaining walls are safe and will not fail. By working with us, you get a retaining wall that meets all requirements and is built right from the start.
