A retaining wall should solve a problem—without creating a new one
When homeowners call Forest Landscaping in Beecher, Illinois, it’s often because a slope is eroding, a yard is hard to use, or an older wall is bowing and cracking. A retaining wall can absolutely fix those issues—if it’s designed for the site conditions (soil, drainage, grade, and loads) and built with correct base prep and reinforcement.
Below is a practical guide for homeowners in the Chicago Southland and Northwest Indiana who are comparing retaining wall builders, weighing material choices, and trying to understand what makes one wall last 3–5 years while another lasts decades.
1) What a retaining wall must do (beyond “hold dirt”)
A well-built retaining wall manages four forces at the same time:
Soil pressure: the lateral push of backfilled soil against the wall.
Water pressure: the hidden “multiplier” that causes many walls to fail when drainage is missing or clogged.
Freeze/thaw movement: common in our region; water in soil expands and shifts the base and backfill.
Surcharge loads: added weight near the wall (driveways, patios, sheds, vehicles, even stacked snow piles).
The best retaining wall contractors start with these realities—then choose the right wall system, footing/base depth, drainage details, and reinforcement for your yard.
2) The “make-or-break” details retaining wall builders should talk about
If a contractor only discusses block style and color, ask more questions. These are the details that separate a decorative border wall from a true retaining wall system:
Base preparation & compaction: A stable, properly compacted base is what prevents settling, leaning, and “stair-step” cracking.
Drainage behind the wall: Quality builds include free-draining aggregate behind the wall and a drainage path to relieve water pressure.
Geogrid reinforcement (when needed): For taller walls or challenging soils/loads, geogrid ties the wall into the slope for stability—one of the most important “invisible” components.
Wall height, terracing, and engineering: Many jurisdictions require engineering at certain heights (commonly around 4 feet) and may require permits. Good contractors know when to terrace, when to engineer, and when to recommend another solution. (montgomerycountymd.gov)
3) Retaining wall types: which one fits your property?
Not every wall should be built the same way. Here’s a homeowner-friendly comparison of common options around Beecher, IL.
| Wall Type | Best For | Watch Outs | What a Pro Will Do |
|---|---|---|---|
| Segmental block wall (SRW) | Most residential grades; clean look; many finishes | Drainage + base errors show up fast as leaning/bulging | Uses correct base depth, drainage stone, and geogrid when required |
| Boulder / natural stone | Rustic properties; informal edges; shorter walls | Can settle if soils are wet/soft; needs equipment access | Keys boulders, builds stable base, and manages drainage to prevent washout |
| Poured concrete | Modern look; tight spaces; specific engineering needs | Cracking without proper reinforcement + drainage | Builds to spec, includes rebar, and relieves hydrostatic pressure |
| Timber wall | Budget projects; short-term landscaping changes | Shorter lifespan; more susceptible to moisture decay | Will usually recommend upgrading for long-term value |
If you’re unsure, a design/build contractor can evaluate grade changes, nearby structures, and water flow to match the wall type to the site—not just the look.
4) Quick “Did you know?” facts (homeowner edition)
Water is the #1 reason walls fail. Even a strong wall can move if water builds pressure behind it—especially after heavy rains or rapid snowmelt.
“Retained height” matters more than “block height.” Permit and engineering requirements are often tied to how much soil the wall is holding back, not just the visible portion. (montgomerycountymd.gov)
Terracing can be safer (and nicer). Two shorter walls with a planting bed between them can reduce pressure and add curb appeal.
5) What to ask retaining wall contractors before you hire
Bring these questions to your estimate. A trustworthy builder will answer clearly and in writing:
How will you handle drainage behind the wall? (Ask where the water goes.)
Will this wall need geogrid reinforcement? If yes, how many layers and how far back?
How deep is the base, and what material is used? (You’re listening for compacted aggregate, not “we’ll just level it.”)
Will permits or engineering be needed? Requirements often change around the 4-foot range depending on conditions and local rules. (montgomerycountymd.gov)
What warranty is provided on workmanship and materials? If Unilock products are used with an Authorized Contractor, Unilock offers a Transferable Lifetime product guarantee (registration required) and a 2-year Peace-of-Mind workmanship guarantee under specific conditions. (unilock.com)
Tip: If you’re also seeing puddling, soggy turf, or downspouts dumping near the wall, solve water first. Forest Landscaping offers dedicated drainage alleviation that can be designed with the retaining wall so both systems work together.
6) Local angle: Retaining walls in Beecher and the Chicago Southland
Beecher-area properties often deal with a mix of drainage patterns, heavy seasonal rains, and freeze/thaw cycles that can punish poorly prepared bases. If your yard sits low, holds water, or funnels runoff toward a slope, a retaining wall should be planned as part of a complete grade-and-drainage strategy, not a standalone “edge.”
Many homeowners also want the wall to do more than stabilize a slope. A well-designed wall can:
Create level lawn space for play, pets, or entertaining
Frame a patio or outdoor kitchen as part of a larger outdoor living space
Add safe steps and transitions on sloped lots (especially near walkways and driveways)
Improve curb appeal when paired with planting upgrades from full-service landscaping
Ready for a retaining wall that’s built to last?
Forest Landscaping designs and builds retaining walls with the “hidden” details handled correctly—base prep, reinforcement, and drainage—so your wall stays straight, stable, and attractive through Midwest seasons.
FAQ: Retaining walls in Beecher, IL
How do I know if my retaining wall is failing?
Common signs include bulging or leaning, stair-step cracks, separating caps/blocks, sinking sections, and persistent wet areas behind or at the base of the wall.
Do retaining walls need permits in Illinois?
It depends on the municipality, the retained height, and whether the wall supports added loads (like a driveway). Engineering is commonly required around the 4-foot range in many jurisdictions, but local requirements vary—your contractor should verify and handle the process. (montgomerycountymd.gov)
What’s the best material for a long-lasting residential retaining wall?
For many homes, a segmental retaining wall (SRW) block system offers an excellent balance of strength, drainage compatibility, and aesthetics. The key is proper base prep, drainage stone, and reinforcement (geogrid) when needed—material alone won’t prevent failure.
Can you build a retaining wall and fix yard drainage at the same time?
Yes—and it’s often the smartest approach. If water is pooling or flowing toward the slope, pairing the wall with a drainage plan can prevent future movement and reduce muddy areas. Learn more about yard drainage solutions.
Does working with a Unilock Authorized Contractor include any warranty benefits?

Glossary (helpful terms when comparing retaining wall quotes)
Retained height: The vertical height of soil the wall is holding back (often used for code/engineering thresholds).
Hydrostatic pressure: Pressure created when water builds up behind a wall. Proper drainage reduces it.
Geogrid: A reinforcing grid placed in layers within backfill to help stabilize taller walls and resist soil movement.
Segmental retaining wall (SRW): A modular block wall system engineered to retain soil, often paired with drainage aggregate and geogrid.
