Spring is the perfect time to refresh your yard, prepare for planting, and enhance your home’s curb appeal. At Alliance Inc., we specialize in designing and building retaining walls that create both functional and beautiful outdoor spaces. Whether you want to prevent soil erosion, create flat planting areas, or add a decorative touch to your landscaping, our retaining walls are an investment that pays off in both form and function.
Retaining walls are more than just a decorative feature. They are built to hold back soil, rocks, or other materials that would otherwise erode or collapse. In spring, when snow melts and rain increases, soil can shift quickly. A professionally built retaining wall helps:
At Alliance Inc., our masonry experts use stone, brick, or concrete to design retaining walls that are both functional and aesthetically pleasing.

Not all retaining walls are created equal. Some walls serve a purely functional purpose, holding back soil and preventing erosion. Others can also act as decorative landscaping features that complement your yard.
Common decorative applications include:
By combining form and function, retaining walls can create an organized, attractive outdoor space that’s ready for spring planting and year-round enjoyment.
Planning and installing a retaining wall requires skill, proper materials, and careful construction. Alliance Inc. handles every step of the process, ensuring your wall is durable, stable, and visually appealing.

How high can a retaining wall be before it needs extra reinforcement? For most residential projects, walls over 4 feet tall require specific engineering and structural reinforcement to handle the “surcharge” (the weight of the earth behind it). We design our walls to account for the specific soil pressure and drainage needs of your property.
What is the best material for a retaining wall in the North Shore climate? Natural stone and heavy-duty concrete blocks are ideal for Duluth. These materials withstand the intense freeze-thaw cycles without cracking or shifting, unlike thinner timber walls which can rot or bow over time.
How do you prevent a retaining wall from leaning or collapsing? The secret to a wall that stays straight for 20+ years is drainage. We install a dedicated drainage system (usually gravel backfill and perforated pipe) behind the wall to prevent hydrostatic pressure—water weight—from pushing against the masonry.
How does the Duluth frost line affect retaining wall construction? Because the frost line in our area can reach depths of 42 to 60 inches, a shallow foundation is a recipe for disaster. We ensure every wall is built on a non-frost-susceptible base of compacted stone. This allows the ground to shift slightly during a hard freeze without heaving or cracking the masonry above.
Whether you’re leveling a sloped yard, creating raised garden beds, or adding natural stone accents, a retaining wall is one of the smartest spring landscaping upgrades you can make.
