Helical Piers - Settling Foundation Repair
Helical Piers are long steel shafts with helical (screw-like) blades that are twisted into the ground using heavy machinery.
What Are Helical Piers?
Helical Piers are long steel shafts with helical (screw-like) blades that are twisted into the ground using heavy machinery. Acting like a giant steel screw, each pier is precisely advanced into the soil until it reaches a firm, load-bearing layer.
Once installed, custom-designed brackets are attached to your home’s foundation to transfer its weight to this stable soil, preventing further settlement. While lifting is not typically part of this process, Helical Piers excel at stabilizing even the most delicate structural areas with unmatched control and minimal disruption.

From the project manager through all the folks working this huge mess, I am so thankful for the job that was completed. Kyle and team put up with all my questions and dealt with temporary fencing for my dogs. Always rrspectful and polite. I can't rate them or Anchored Walls high enough! Also Deb in the office keeping me updated and answering more questions. Lucas and Carson putting in the sump pump. If you have basement issues, definitely call this company!!

After getting bids and talking with a few different contractors regarding what we needed for waterproofing our basement, I was feeling pretty overwhelmed, anxious and stressed out. Elliott was a breath of fresh air. He's a very nice, respectful guy. He is very knowledgeable and was easy to talk to. After speaking with him, I felt more at ease and less anxious about the whole process. Because of Elliott, we plan to move forward with Anchored Walls for our basement waterproofing.

Why Foundations Settle
Foundation problems often begin with soil movement. When part of your footing rests on poorly compacted fill dirt or moisture-sensitive soil, it can settle faster than other areas—this is known as differential settlement. Over time, this uneven support can cause cracking, bowing, and shifting throughout your home.
How Our Helical Pier System Works
- Free Expert Inspection
We inspect your foundation and determine load requirements based on the size and structure of your home. - Precision Installation
Using specialized machinery, Helical Piers are twisted into the soil like a screw until they reach competent, undisturbed earth. Real-time torque readings ensure the correct depth and load-bearing capacity. - Secure Foundation Transfer
Brackets are mounted to the footing to transfer the weight of your home to the installed piers. This stabilizes the structure without relying on hydraulic lifting. - Minimal Restoration
Only small 3' x 3' areas are excavated during installation. Once complete, we backfill and restore the site with minimal impact to landscaping or flooring.
Why Choose Helical Piers from Anchored Walls?
- Pinpoint Accuracy: Ideal for sensitive areas like corners, garages, and tight access zones.
- No Heavy Excavation: Quick installation with minimal disruption.
- Proven Engineering: Each pier is driven to verified depths based on site-specific conditions.
- All-Weather Performance: Can be installed year-round, regardless of weather.
- Patented Technology: We use a proprietary, ICC-certified Helical Pier system.
- Warranty-Backed: Includes Lifetime transferable warranty and Money-Back Guarantee.
When Are Helical Piers the Right Choice?
Helical Piers are ideal when:
- You need a permanent solution without risk of further settlement.
- Soil conditions prevent standard footings from holding.
- Exterior access is available for installation.
- The structure requires non-invasive, targeted support.

“Anchored Walls did anchors and a full water-proofing system on my dad’s lake house. They were so great to work with from their sales team (Matt), to their front office (Maddy & Deb), their production manager (Lucas), and the foreman and his crew (Kyle & Sopheak). Their GM, Brad, even checked in to make sure everything…”

Frequently Asked Questions
Why is there mold in my crawl space?
Mold is a result of excessive moisture in the crawl space of your home. It’s very important that you take care of a moldy crawl space problem as soon as you notice that something is wrong. If left untreated, mold can cause a number of problems for the structural integrity of your home, as well as your family’s health. If you don’t repair your foundation, water will eventually seep in. This causes an assortment of additional problems for the structural integrity of your home.
How much does foundation repair cost?
According to This Old House, most foundation repair projects range from $2,000 to $10,000, depending on the size of the home, the type of foundation, and the severity of the damage. Small crack repairs may fall near the lower end, while structural issues that require stabilization or piering will be higher. Every home is different, but a professional inspection can help identify the most cost-effective path forward.
Are foundation cracks serious or just cosmetic?
Some small, vertical cracks may be normal settling, but if a crack is widening, leaking water, or forming a stair-step or horizontal pattern, it could signal a structural issue. It’s always best to have cracks professionally evaluated to determine whether repair is needed.
If I don't repair my foundation, what could happen?
If you don’t repair your foundation, water will eventually seep in. This causes an assortment of additional problems for the structural integrity of your home.
What causes foundation problems in the first place?
Most foundation issues are caused by changes in the soil around your home. Drought, heavy rain, poor drainage, and construction on improperly compacted soil can all lead to movement under your foundation. Over time, this movement creates stress on the structure and leads to cracks, shifting, or settling.
