Retaining Wall Contractors & Installation in Anoka and the North Metro

Looking for retaining wall contractors or builders in Anoka and the North Metro? Steve’s Lawn and Landscape has been building and repairing retaining walls throughout Anoka County since 1997 — granite and fieldstone boulder walls, concrete block walls, natural stone, timber, and decorative garden walls. We also handle full retaining wall replacement of failed and failing installations, and build walls that tie seamlessly into your patio and hardscape design.

A well-built retaining wall transforms a sloped grade into an asset — creating flat, usable outdoor space, adding visual interest, and making room for walkways, stairways, and planting areas that would otherwise be impossible. That said, retaining walls are not DIY projects. They require real engineering skill, and getting one wrong — wrong base, wrong drainage, wrong material — means it fails. Minnesota’s freeze-thaw cycles are relentless, and I’ve seen plenty of walls come apart that weren’t built to handle them. Browse the services below, or call or text Steve directly for a free on-site estimate.

Boulder & Natural Stone Retaining Walls

Boulder and natural stone walls are our most-requested wall type — and the one we most enjoy building. We invested in specialized excavator equipment specifically for boulder work, which means we can set large stones faster, more precisely, and with less disruption to your property than most contractors. Granite boulders, limestone, and fieldstone transform a sloped grade into something you actually want to look at — creating opportunities for planting beds, stairways, and walkways that make the whole yard work better.

One thing that surprises most homeowners: boulder walls are almost always less expensive than concrete block walls — often by thousands of dollars. The material costs less, and our equipment makes the install significantly more efficient. And unlike block walls, if a boulder settles even slightly over decades, you’ll never notice. Stone has a way of looking natural no matter what. No two boulder walls look the same, and done right, they’ll outlast just about anything else you can build on your property.

We source primarily fieldstone due to cost, along with limestone, granite, and other stone types — sourced from Plaisted’s in Elk River and Rock Hard Landscape Supply in Andover.

• Granite boulders, limestone, fieldstone & natural stone options
• Structural walls engineered for Minnesota’s freeze-thaw cycles
• Drainage aggregate and fabric installed behind every wall
• One-of-a-kind look — no two boulder walls are identical
• Usually thousands less than comparable concrete block installations

Concrete Block Retaining Walls

Concrete block retaining walls — built with interlocking systems like Versa-Lok, Keystone, and County block — deliver a clean, structured look and are extremely durable when installed correctly. They come in a wide range of textures and colors to match your home’s exterior. The difference between a block wall that holds for decades and one that fails after a few Minnesota winters comes down entirely to what’s underneath and behind it: the right base material, proper drainage backfill, and geogrid reinforcement where the engineering requires it.

One thing to keep in mind: block walls show imperfections more than boulder walls do. If a block wall settles even slightly over time, it can look noticeably uneven. That’s not a reason to avoid block — it’s a reason to make sure whoever builds yours does it right.

• Versa-Lok, Keystone, County block & interlocking concrete block systems
• Geogrid reinforcement included where engineering requires it
• Wide range of textures, colors & block profiles available
• Compacted base and drainage backfill — built to hold through freeze-thaw cycles

Timber Retaining Walls

For shorter walls — typically under 4 feet — pressure-treated timber is a practical, cost-effective option that fits naturally into certain landscape styles. We use landscape timbers and railroad ties, properly deadmanned into the hillside for stability. We’ll be upfront with you: timber has a lifespan of 15–25 years depending on moisture exposure, and it’s become less popular as homeowners learn that boulder and block alternatives often cost less long-term. If you want something permanent, boulder or concrete block is the better investment. If timber fits your project’s scope and budget, we’ll build it right.

• Properly deadmanned for stability and load resistance
• Cost-effective option for walls under 4 feet
• Honest guidance on lifespan vs. boulder and block alternatives

Retaining Wall Repair, Replacement & Rebuilds

Most wall failures come down to two things: poor drainage and an inadequate base. When we tear out a failed wall, the same three problems show up almost every time — no drainage rock behind the wall, not enough compaction near the base, and no geogrid. We assess and rebuild failing concrete block, boulder, natural stone, and timber walls — fixing the cause of the failure, not just the visible damage. Whether you need targeted repair or full retaining wall replacement, we’ll give you a straight recommendation on the right call.

• Assessment of leaning, bowing, or failing block, boulder & timber walls
• Full retaining wall replacement or targeted repair — we recommend what’s right
• Drainage corrections that address the actual cause of failure
• Serving Andover, Ham Lake & Anoka County

Decorative Garden Walls

Not every wall needs to hold back a hillside. Decorative garden walls define landscape beds, create raised planters, border walkways, and add visual interest to a flat yard — and they’re one of the highest-impact additions you can make alongside a patio or landscape renovation. We build them using the same materials as our structural walls so everything looks cohesive.

• Natural stone, boulder & concrete block garden wall options
• Raised planters, landscape bed borders & walkway definition
• Walkways and stairways integrated into the wall system
• Often combined with patio installations and landscape renovations

Our Retaining Wall Process — Built for Minnesota’s Climate

Most retaining wall failures are process failures. Here’s exactly how we build every wall to ensure it lasts for many years:

Step 1 — Site Assessment & Design. We assess drainage patterns, soil type, grade change, and load requirements before recommending a wall type or spec. Most wall layouts are straightforward enough that we design them on-site during the consultation — no extra fees for that. If you want to see it in 3D before we break ground, we can produce renderings in our Realtime Landscaping software.

Step 2 — Excavation & Base Preparation. We excavate to the required depth and compact the native soil before any base material goes in. For walls over 4 feet, we handle the engineering review and permitting process — that’s required by code and we take care of it.

Step 3 — 3/4″ Clear Stone Footing Base. We install 6 inches of 3/4″ clear stone as the wall footing. This is what manufacturers specify — and for good reason. Class 5 crushed base holds moisture and goes soft when wet, causing freeze-thaw heaving. Clear stone doesn’t hold moisture, drains completely, and locks together and compacts better. It’s simply a more reliable foundation material.

Step 4 — Drainage Installation. We install 6–12 inches of 3/4″ clear rock behind the wall (depending on wall height, soil conditions, and drainage) along with a 4″ perforated drain pipe to collect and divert water away from behind the wall. Geotextile fabric separates the drainage zone from the native soil to prevent silting. Water management is built in — not added as an afterthought.

Step 5 — Wall Construction. Whether we’re setting boulders, stacking concrete block, or building in natural stone, each course is leveled and checked side-to-side and front-to-back. On taller block walls, geogrid reinforcement is installed at the required intervals per the manufacturer’s engineering specs. Cap block is cut and glued to fit.

Step 6 — Backfill, Cleanup & Walkthrough. We backfill with clean material, restore any disturbed turf with black dirt and seed or sod, clean up all debris, and walk you through the finished wall before we leave.
