This article is brought to you by TLC Incorporated — Maryland’s trusted team for honest soil and structural solutions, led by Bob Carr.
Hi, I’m Bob Carr. If you’re seeing steps pull away, concrete settle, or a porch dip unevenly, you’ve probably heard about two possible solutions:
Install helical piers, or rebuild the soil base beneath.
Let’s break down what each approach involves, when they’re used, and what homeowners around Maryland are actually paying in 2026.
1. What Are Helical Piers?
Helical piers are long steel shafts with screw-like blades that are drilled deep into the ground until they reach solid, load-bearing soil or bedrock. Once installed, brackets attach to the base of the structure and lift or support it.
Common Use: – Severe foundation settlement – Homes on poor fill or near wetlands – Structural elements requiring permanent lift
They work well — when used for the right problem. But they don’t fix water, erosion, or surface-level issues.
2. What Is Soil Rebuilding?
Soil rebuilding is exactly what it sounds like — removing weak or washed-out soil, compacting fresh layers in lifts, adding gravel or sand for strength, and correcting slope and drainage around the area.
Common Use: – Steps, sidewalks, patios, and porch landings – Mild to moderate settling from erosion or poor drainage – When water — not structure — is the root issue
TLC Insight: Many piers are installed where the real problem is surface water — not deep instability.
3. Cost Comparison (2026 Pricing)
| Solution Type | Typical Cost Range | Notes |
| Soil Rebuilding | $2,500–$5,500 | Includes excavation and compacted base |
| Soil + Drainage Correction | $4,500–$8,500 | Includes pop-up drain or slope regrading |
| Helical Piers (per pier) | $1,800–$2,800 | Often 3–6 piers needed |
| Complete Pier System | $9,000–$18,000+ | For major settlement or structural cracks |
Bob’s Note: In 80% of walkways, porches, or patio fixes we see, soil rebuilding solves the problem without piers.
4. When Piers Make Sense
- Vertical displacement exceeds 2 inches across foundation
- Cracking follows a staircase or shear pattern
- Foundation has no apparent water issue, but keeps dropping
- Interior damage (drywall cracks, sticking doors) is worsening
Homeowner Insight: “The piers worked on the corner of our foundation. But for the walkway and porch — Bob was right. It was drainage.”
5. When Soil Rebuilding Solves the Problem
- Water is clearly to blame (downspouts, slope, erosion)
- Steps or landings drop but don’t crack heavily
- Slab tilt is consistent and slow over time
- Home is on clay and expands/contracts with rain
Soil rebuilding includes: – Removing loose or compromised fill – Compacting new soil in 4” lifts – Adding gravel or sand for stability – Installing drains to redirect water away
Bonus: It often improves lawn health, prevents future erosion, and protects crawl spaces or finished basements.
6. Case Study #1: Glen Burnie, MD
A homeowner had two contractors quote piers for front steps that had sunk 1.25” over 7 years.
We found: – No gravel base – Downspout within 4 feet of the slab – Sidewalk slope funneled runoff toward the entry
Our fix: – Rebuilt sub-base with gravel and compacted fill – Buried downspout and rerouted 35 feet downslope – Regrouted stair joints and reinforced paver edges
Total Cost: $5,200
Quote: “It wasn’t the structure — it was the water. You saved us thousands.”
7. Case Study #2: Ellicott City, MD
This client had a porch slab that dropped 2 inches. One contractor said piers were the only answer.
What we saw: – Soggy clay soil underneath – Block foundation untouched — no cracking – Gutter system dumped water right under porch
TLC Fix: – Removed slab – Installed gravel and compacted soil in layers – Buried 40’ of downspout with pop-up emitter
Total Cost: $6,400
Homeowner Feedback: “I almost paid $12k for something I didn’t need. Bob’s team fixed the real issue.”
8. Case Study #3: Davidsonville, MD (When Piers Were Right)
We evaluated a corner of a historic home that had settled 3 inches. The cracking was deep and shifting doors indicated active foundation movement.
Our plan: – Installed 4 helical piers to stabilize that corner – Rebuilt front steps and tied them into new porch landing – Regraded slope and rerouted water away
Total Cost: $16,800
Why it worked: The piers were used where they belonged — and the soil was fixed too.
9. Checklist: Do You Need Piers or Soil Rebuilding?
Answer these questions:
- Are there wide cracks running through block or drywall?
- Have doors/windows started sticking in the same area?
- Is your slab sinking but the foundation wall is untouched?
- Do you have visible water drainage issues nearby?
- Did this issue appear gradually after heavy rain or erosion?
TLC Tip: If water caused the problem — water control and soil rebuilding should be the first line of defense.
Final Thoughts From Bob
If your concrete is settling, don’t let fear — or pushy sales tactics — drive the fix.
Get someone who will look at the big picture. At TLC, we inspect the drainage, grade, soil, and structure. We explain the why before we talk about the how much.

Because sometimes the strongest fix isn’t steel — it’s smart, stable soil that’s done right from the ground up.
