Retaining Walls & Structural Hardscape

When the ground needs to stay put, we make sure it does.

From natural boulder walls to engineered structural block systems, Maplewood Site Solutions designs and builds retaining walls for residential properties, rural acreages, shorelines, and commercial sites — walls that won’t lean, settle, or fail when conditions get tough.

What We Do

Retaining Wall Construction for Every Site Condition

Not all retaining walls are created equal. A decorative garden border and a wall holding back a 10-foot cut slope are two entirely different engineering challenges — and they demand different materials, construction methods, and expertise.

As a dedicated retaining wall contractor, Maplewood Site Solutions focuses on the structural side of hardscape construction. We build walls engineered to manage real forces — and that perform reliably for decades without costly repairs or failures.

Our Services

Retaining Wall & Structural Hardscape Services

Large fieldstone and granite boulders interlock by weight and friction, creating a massive, stable structure that blends naturally into rural and residential landscapes — with serious holding power and exceptional longevity.

Flat-faced, coursed stone with proper batter, compacted base, and drainage aggregate behind the wall face. A clean, layered look that complements both traditional and contemporary landscapes.

Engineered segmental retaining wall (SRW) systems for residential terracing, driveway support, building pad retention, and commercial grade separation — installed with proper base compaction, drainage, and setback.

Taller walls with geogrid reinforcement layers extending into the retained soil mass — built to resist surcharge loads, challenging soils, and the engineering demands of walls beyond three to four feet.

Riprap and boulder armoring, bank regrading, and shoreline retaining wall construction sized for real wave, ice, and saturation conditions — protecting docks, lawns, and waterfront property from active erosion.

Strategic placement of large boulders to anchor slopes, deflect water, define property features, or create natural-looking landscape elements with real structural function — using the right equipment for precision setting.

Comprehensive solutions combining grading, retaining structures, drainage improvements, and erosion control — addressing the root cause of slope instability rather than treating symptoms.

Clean, stable transitions between elevations on your property — protecting driveway edges, supporting building pads, and retaining lawn areas adjacent to lower grades for the long term.

Large segmental walls, boulder and riprap systems, and reinforced load-bearing structures for retail sites, storage facilities, multi-unit developments, and light industrial properties — built to spec, on schedule.

What Makes a Retaining Wall Fail

Understanding why walls fail explains why quality construction matters so much. Here’s how we prevent the most common causes.

Failure Cause

How We Prevent It

Inadequate base preparation

We excavate and compact a proper base for every wall

No drainage behind the wall

We install drainage aggregate and pipe to relieve hydrostatic pressure

Improper batter and setback

We build walls with correct lean and geometry for the load

Undersized for the application

We size wall systems to match the actual forces involved

No geogrid reinforcement on taller walls

We use reinforcement layers where wall height and loads require it

Poor material selection for site conditions

We match materials to exposure, soil type, and load requirements

A wall built correctly from the start costs less in the long run than repairing or rebuilding one that failed due to shortcuts.

Why Choose Us

Why Choose Maplewood Site Solutions

A retaining wall is a long-term structural investment. You want a contractor who treats it like one.

Engineering-First Approach

Walls designed and built to manage hydrostatic pressure, soil weight, surcharge loads, and frost heave — not just stacked stone.

Right Material for the Job

Boulders, ledge stone, structural block, or reinforced systems — matched to your site, load, and aesthetic.

Drainage Done Right

Every wall built with proper drainage aggregate and outlet — the most common cause of wall failure, eliminated.

Equipment & Expertise

Heavy equipment for boulder setting and the experience to place every stone correctly the first time.

Built to Last Decades

Walls that won't lean, settle, or fail — a one-time investment, not a recurring repair.

FAQ

Frequently Asked Questions

How tall can a retaining wall be before it needs engineering?

Requirements vary by municipality, but most jurisdictions require engineering review for walls exceeding four feet in retained height. Walls supporting surcharge loads — like driveways or structures above — may require engineering at lower heights. We’ll advise you on what’s required for your specific project.

Boulder walls are among the most durable — their mass and natural interlocking make them extremely resistant to failure. Properly built structural block walls with geogrid reinforcement are also highly durable. The “best” material depends on your site conditions, load requirements, and aesthetic preferences.

Yes — without exception. Hydrostatic pressure from water building up behind a wall is one of the leading causes of wall failure. Every wall we build incorporates drainage aggregate and, where appropriate, drainage pipe to relieve this pressure.

A typical residential retaining wall project takes two to four days depending on wall length, height, and material. Larger commercial or shoreline stabilization projects may require additional time. We provide a project timeline with every estimate.

In most cases, yes. If you have an existing boulder, ledge stone, or block wall that needs to be extended or complemented with a new section, we’ll do our best to match the material and construction style.

A retaining wall is specifically engineered to hold back soil and manage grade changes — it must be built to handle real structural loads. A landscaping wall is primarily decorative. Many walls serve both purposes, but any wall retaining significant soil height or supporting loads above needs to be built to structural standards.
