Foundation repair comparisons

The main comparisons are steel push piers versus helical piers for supporting a settled foundation, mudjacking versus polyurethane foam for raising sunken concrete, and carbon fiber straps versus wall anchors for a bowing wall. In 2026 HomeCostLab puts steel push piers at $1,000 to $3,000 per pier and helical piers at $1,500 to $3,500, mudjacking at $500 to $1,500 and foam injection at $1,000 to $3,000, carbon fiber strips at $300 to $700 each and wall anchors at $500 to $1,000 each.

Piers versus slab leveling. These solve different problems. Piers transfer the weight of the structure down to deeper, more stable ground. Slab leveling raises a concrete slab that has sunk by injecting material underneath it. Concrete driveways, patios and garage slabs are common slab-leveling jobs. A house that is structurally settling is not.

Push piers versus helical piers. Both carry load to deeper soil; they are installed differently and priced differently, and the right one depends on soil and on how much structure weight is available. This is a genuine engineering judgment, not a marketing preference — which is why it is worth having someone who does not sell either one tell you which applies.

Mudjacking versus polyurethane foam. Cost is the visible difference — HomeCostLab puts mudjacking at $500 to $1,500 versus $1,000 to $3,000 for foam. They also differ in the weight of material added and in hole size. Neither addresses why the slab sank.

Carbon fiber versus wall anchors. Both address walls under lateral soil pressure and are the cheapest line items in the list — but which is appropriate depends on how far the wall has already moved and whether you need to hold it or straighten it. Do not choose this one on price.

How to choose

Compare methods only after the cause is settled: Choosing between methods before you know what is moving and why is choosing between answers to a question nobody has asked yet.
Distrust companies that offer only one method: A contractor who sells one product will find that one product is the answer. That is not fraud, it is incentive. Get bids from companies with different toolkits.
Ask what the method does not fix: Every method has a boundary. Foam does not stop soil moisture swings. Piers do not fix a plumbing leak. A good contractor will tell you the limits.
Price differences are small next to being wrong: The gap between mudjacking and foam is a few thousand dollars. The gap between the right diagnosis and the wrong one is often twenty.

FAQ

Foundation Repair comparisons — common questions

Still have a question? Talk to our team →

Are helical piers better than push piers?

Neither is universally better. They suit different soil and loading conditions. HomeCostLab prices helical piers higher — $1,500 to $3,500 versus $1,000 to $3,000 — but price is not the deciding factor; site conditions are.

Is polyurethane foam worth the extra cost over mudjacking?

It depends on the slab and the site. Foam costs $1,000 to $3,000 versus $500 to $1,500 for mudjacking per HomeCostLab. Ask each contractor to explain, in writing, why they recommend theirs for your specific slab.

Can carbon fiber straps straighten a bowing wall?

That depends on how far the wall has moved and what is behind it, which is exactly the kind of question that needs an engineer on site rather than a general answer.
