By installing helical piers before the concrete slab or footing is poured, we can create a stable foundation system that reaches deep into more reliable soil.
Building on Unstable Soil? Start with the Right Foundation Support
By installing helical piers before the concrete slab or footing is poured, we can create a stable foundation system that reaches deep into more reliable soil. This gives your new build the support it needs from day one, avoiding future problems like sinking, cracking, or shifting.

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.

How Preconstruction Helical Piers Work
Helical piers are steel shafts with helical (spiral) blades that are rotated deep into the ground until they reach load-bearing strata. These piers are then used to support the foundation of the new structure, transferring the load away from soft or unstable surface soil and into more stable ground below.
Preconstruction pier systems are designed for new builds, meaning there’s no need to lift or correct anything. Instead, they provide support before any settling can occur, making them ideal for additions, custom homes, commercial structures, or any project built on poor soil conditions.
When to Use Helical Pier Underpinning Before Construction
Preconstruction helical piers are ideal for stabilizing foundations before any concrete is poured. Whether you’re building a new home, adding onto an existing structure, or working on light commercial construction, here are common situations where this solution makes sense:No matter the project, starting with solid support means fewer surprises down the road. Anchored Walls helps homeowners and builders make smart decisions based on real soil performance, not guesswork.
Weak or loose surface soils
If the top layers of soil can’t support the weight of a structure, the foundation may begin to settle or shift soon after construction. Helical piers bypass these upper layers and anchor into stronger soil below, providing a more reliable base from the start.
Expansive clay or high water tables
Some soil types expand when wet and shrink when dry, creating constant movement beneath the foundation. Piers reduce the impact of this swelling and shrinking by transferring loads deeper, where conditions are more stable.
Fill soil that lacks compaction
Lots that have been leveled with imported fill may not offer the same strength as undisturbed native ground. Unless the soil has been properly compacted, preconstruction piers help prevent settlement caused by weak or shifting fill material.
Sloped lots or uneven terrain
Building on a hillside or sloped surface increases the risk of foundation movement over time. Helical piers add structural stability and help support uneven loads across varying elevations.
Known history of settling foundations
If other homes or buildings in the area have required foundation repair, it’s a smart move to reinforce your project before it begins. Helical piers provide a safeguard against repeating the same problems.

“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.
