When Deep Foundation Systems Are the Right Repair
Deep foundation systems skip the surface soil entirely and stand your structure on strata that stopped moving long ago, with each element proving its capacity as it goes in.
Let's take the first step toward solid ground.
A local specialist will evaluate your foundation, walk you through the findings, and send a clear estimate. No cost, no pressure.
What to know about deep foundation systems, and when it's the right call.
Every deep foundation works on the same principle: find soil that can carry the load, and connect the structure to it with something that will not shorten, rot, or wander. The differences are in how each element gets there and how it proves itself. Helical piles rotate into the ground, their screw plates pulling the shaft down through weak material, and installation torque correlates with soil capacity, so every pile arrives with a logged number behind it. Push piers are driven hydraulically using the structure's own weight, and the driving resistance is the proof test. Micro piles, a third type, are drilled and grouted and are specified by engineers where soils or access defeat the other two; our own deep foundation work uses helical piles and push piers. In every case, the element passes through the moisture active zone, the layer where clay swells and shrinks with the seasons, and seats in ground below it, so the surface soil can do whatever it likes without the structure hearing about it. Brackets or caps then tie the foundation to the deep elements, completing the load path from framing to competent strata.
The symptoms that usually lead to deep foundation systems are on the foundation repair problem signs page, alongside the other signs that point to the same underlying cause.
How we install deep foundation systems.
Free evaluation with elevation measurements
We measure elevations, assess loads and soil behavior, and confirm the problem genuinely needs a deep system rather than a smaller repair. Deep foundations are the right tool often enough that we never need to oversell them.
System design
Element type, count, spacing, and target capacities are engineered from the structure's loads and the soil profile, with helical piles the usual choice and push piers where conditions favor them.
Install to verified capacity
Each pile or pier is advanced until its torque or driving resistance records prove it can carry its assigned load. Depth is not the target; verified capacity is.
Connect the structure
Brackets, caps, or new footing connections tie the foundation to the deep elements, transferring the load from surface soil to steel standing on competent strata.
Verify and document
Installation logs and final elevation checks are reviewed with you, so the record shows what went in, how deep, and what it proved.
New ground for an old footing.
When the soil under a footing cannot carry the house anymore, underpinning gives the footing something better to stand on: steel piers that reach down to soil that does not move.

Care and expertise from a team that's been doing this since 2011.
When the fix is deep foundation systems, the installer matters as much as the method. Dalinghaus crews handle foundation, concrete, and crawl space work across California, Arizona, and Nevada, and nothing else.
Foundation repair, concrete leveling, and crawl space repair are our entire focus. Not a sideline.
More than 2,000 projects on the clay and desert soils of California, Arizona, and Nevada since 2011.

Warranty terms come in writing with every proposal, and the terms that apply to your job are stated in that job's paperwork. Ask your project specialist during the free evaluation.
Answers to common questions about Deep Foundation Systems.
Don't see your question here? Our team is happy to help. Reach out anytime.
Any foundation element that carries load past the surface soil to deeper bearing strata: helical piles, push piers, drilled micro piles, and the caisson and pile systems of heavy construction. For residential and light commercial work in our region, helical piles do most of the lifting because they install fast, need small equipment, and log their own proof of capacity.
Other foundation repair solutions we install.
Every solution is engineered for a specific soil profile and failure mode. Browse the full toolkit.
Carbon Fiber Reinforcement
Carbon fiber straps bond to a stressed foundation wall and refuse to stretch, so the wall that was slowly losing to soil pressure simply stops moving.

Epoxy & Polyurethane Crack Injection
Epoxy welds a structural crack back into one piece; polyurethane chases water through a wet one and seals it shut. Choosing correctly between them is most of the repair.

Foundation Underpinning
Underpinning does not patch a settling foundation, it reaches underneath and hands the load to soil that stopped moving long before your house was built.

Grout Injection (Chemical Grouting)
Chemical grouting injects grout directly into weak, loose ground, bonding the particles into a soil that can finally carry what sits on it, no excavation required.

Helical Deck Piers
Helical deck piers screw galvanized steel down past the surface clay that heaves and shrinks with the seasons, so your deck stands on ground that has stopped arguing with the weather.

Helical Piers
Helical piers carry your home past the unstable clay to load bearing strata, and the torque reading on every pier proves it before we transfer a pound of weight.
