Fix the soil instead of fighting it.
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.
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 grout injection (chemical grouting), and when it's the right call.
Weak soil fails because its particles have too much empty space between them: the grains slide, compress, and wash apart under load. Permeation grouting fills that space. The crew drives injection pipes to the target depth in the weak zone, then pumps grout under controlled pressure. The material flows outward through the pore network the way water would, permeating the loose mass rather than displacing it, and as it cures it binds the particles into a coherent, stiffer body with real load bearing behavior. Where distinct voids exist, washouts under slabs, gaps left by decomposed material or old utility trenches, the grout fills them solid before they can collapse. Injection points are laid out in a grid so treated zones overlap, and the crew monitors pressures and volumes at each point, which reveal how the ground is taking the material. The result is soil that behaves like the ground your foundation assumed it was built on.
The symptoms that usually lead to grout injection (chemical grouting) are on the foundation repair problem signs page, alongside the other signs that point to the same underlying cause.
How we install grout injection (chemical grouting).
Free evaluation with elevation measurements
We measure elevations, probe the settlement pattern, and identify whether the problem is loose soil and voids, which grouting treats, or deep settlement and expansive clay, which need different tools.
Injection plan
Injection point layout, depths, and grout volumes are planned from the evaluation so treated zones overlap and the whole weak area is addressed.
Drive injection pipes
Small diameter pipes are advanced to the target depths, with no trenching and minimal disturbance to slabs and landscape.
Inject and monitor
Grout is pumped under controlled pressure while the crew tracks volumes and pressures at each point, confirming the ground is taking material where the plan calls for it.
Verify and document
Injection records and final elevation checks are reviewed with you, documenting what was treated and confirming nothing moved that should not have.
The soil itself gets fixed.
Low-mobility grout is pumped in controlled stages beneath the structure. Each bulb of grout compacts the loose soil around it, turning weak ground into dense, load-bearing ground.

Care and expertise from a team that's been doing this since 2011.
When the fix is grout injection (chemical grouting), 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.
CSLB License #983851 in California, ROC #330307 in Arizona, and License #0089738 in Nevada. Look us up with the state before we ever set foot on your property.
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 Grout Injection (Chemical Grouting).

Strengthening loose, poorly compacted soil and filling voids without excavation. It turns ground that slides and compresses into a bonded, stable mass, which makes it a strong choice for washouts under slabs, bad fill, and soil weakened by past leaks, and a useful companion to other repairs that need firmer ground around them.
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.

Deep Foundation Systems
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.

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.

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.
