Get to know Nova Concrete

Retaining walls solve two problems at once: they stop soil from shifting where it shouldn't, and they give your yard structure worth looking at. Nova Concrete has been building and replacing retaining walls across the Twin Cities metro since 2005, and every project we take on is backed by a 1-year warranty and full insurance coverage. If you've got a slope that's eroding, a yard that's losing grade, or a hillside that's starting to lean on something it shouldn't, don't wait. Call us at (612) 462-2610 for a free estimate before a manageable problem becomes a structural one.

The cost of a retaining wall depends on factors like wall height, length, material selection, site access, and how much excavation the ground requires. Modular block, reinforced concrete, and lock-block systems each carry different material and labor costs, and a large retaining wall on a steep grade is a fundamentally different undertaking than a modest landscape border. For most residential projects in the Twin Cities area, ranges vary widely based on those conditions. Every job is different — contact Nova Concrete for an accurate estimate.

Why Retaining Wall Design Requires More Than Good Materials

A wall that looks solid from the outside can fail quietly from behind. Hydrostatic pressure builds when water can't escape through or around a wall's base, and it's one of the most common causes of premature failure we see on replacement jobs. Drainage isn't optional. It's the difference between a wall that lasts twenty years and one that leans three years after installation. We specify proper batter angles, drainage aggregate, and outlet points as standard practice, not as add-ons. The footing matters just as much: footings that aren't set below Minnesota's frost line will heave in winter and shift in spring. That's the hard truth about retaining wall installation in the Upper Midwest.

Retaining Wall Materials: What Works and What to Expect

Walls can be built from several materials, and the right choice depends on your site conditions, your aesthetic preferences, and how much load the wall needs to carry. Modular block retaining walls are a reliable, cost-effective option for residential grades up to four feet, offering clean lines and good drainage compatibility. Reinforced concrete retaining walls are the standard for larger retaining walls, taller grades, or commercial applications where structural integrity is non-negotiable. Lock-block systems work well for heavy-duty residential and light commercial applications where mass and gravity do the structural work. We also work with natural stone and timber-framed options where clients want something that integrates with existing stamped concrete or patio surfaces. The material choice affects the wall's visual character as much as its structural behavior, and we won't steer you toward a more expensive option if a simpler system does the job correctly.

What the Installation Process Looks Like, Start to Finish

Every retaining wall project starts with a site assessment: we read the slope, identify drainage patterns, check what's above and below the wall line, and determine what the soil composition requires for a stable base. From there, excavation removes material down to the footing depth, which in Minnesota means going below the frost line to prevent seasonal movement. The base course is set on compacted aggregate, leveled precisely, and checked before any subsequent course is placed. Batter (the slight backward lean of the wall) is built in as we go, not corrected at the top. Drainage aggregate is packed behind the wall in lifts as the height increases, and drainage pipe is set at the base to give water somewhere to go. We don't rush the base work. If the first course isn't right, nothing above it will be either.

When to Call a Professional vs. Attempting a Retaining Wall Yourself

Walls under two feet in height on a stable, level site are the realistic upper limit for a confident DIY project. Honestly, even at that scale, most homeowners underestimate how much base prep and compaction matter. Once a wall exceeds four feet, or holds back a slope above a walkway, driveway, or structure, professional engineering and installation aren't optional. A wall failure at height can damage property, destabilize foundations, and create liability. Minnesota also has specific requirements around walls near property lines and utility corridors. Any contractor who won't walk your site before giving you a quote is guessing. We don't quote retaining walls blind.

Our Retaining Wall Work Across the Twin Cities Metro

Nova Concrete has completed residential and commercial retaining wall projects throughout the Twin Cities metro, including Plymouth, Burnsville, St. Paul, Blaine, Lakeville, Brooklyn Park, Cottage Grove, Andover, Apple Valley, Coon Rapids, Eagan, Eden Prairie, Edina, Inver Grove Heights, Maple Grove, Maplewood, Minneapolis, Minnetonka, Richfield, Roseville, Savage, Shakopee, St. Louis Park, and Woodbury. Walls designed for constrained nooks and sloped residential yards account for much of our work, but we also take on large-scale commercial retaining wall projects where code compliance and structural documentation are part of the deliverable.

FAQ

Common Questions About Retaining Wall Installation

Answers to what homeowners and property managers most often ask before starting a retaining wall project.

How deep does a retaining wall footing need to be in Minnesota? +
In Minnesota, footings for permanent retaining walls should be set at least 42 to 48 inches below grade to clear the frost line. Walls with footings above the frost line are almost certain to shift, crack, or lean over time as the ground freezes and thaws each season. This is a non-negotiable part of the spec for any wall meant to last more than a few years.
What kind of drainage does a retaining wall need behind it? +
A properly built retaining wall needs a drainage aggregate backfill (typically clean crushed stone, not topsoil or native fill) and a perforated drain pipe at the base of the wall running to a daylight outlet or storm drain. Without it, water pressure builds behind the wall and pushes against it from within. We include drainage specification in every wall design we build.
What is the difference between a modular block retaining wall and a reinforced concrete retaining wall? +
Modular block walls use interlocking manufactured units stacked with gravity and batter providing the structural resistance. They work well for walls up to four feet in residential applications. Reinforced concrete retaining walls use poured concrete with steel rebar, offering significantly higher load capacity and durability for taller walls, heavy surcharge loads, or sites where the wall supports a structure or driveway above.
How long does a retaining wall installation take? +
A standard residential retaining wall of 30 to 50 linear feet typically takes two to four days of on-site work, depending on material, wall height, and site prep requirements. Larger or more complex walls, or those requiring significant excavation or drainage work, take longer. We set realistic timelines during the estimate process and don't over-promise on schedule.
Can a retaining wall add property value? +
A well-designed retaining wall can meaningfully increase usable outdoor space, which translates to property value. Sloped lots that would otherwise be difficult to landscape become level areas suitable for patios, garden beds, or lawn space. Pair a retaining wall with a concrete patio or walkway system and you're converting unusable grade into an outdoor living area that appraisers and buyers notice.
What is the warranty on a Nova Concrete retaining wall? +
Nova Concrete provides a 1-year warranty on all retaining wall installations. Full warranty details are available at our warranty page. We stand behind the footing depth, drainage installation, and material placement. If something moves or shifts within the warranty period due to a workmanship issue, we come back and fix it.
