Foundation repair
at project scale.
Engineered solutions for general contractors, developers, property managers, ag operations, and structural engineers across California, Arizona, and Nevada.
Industries We Serve
Who we work with.
Audience-specific expertise, with services, specs, and processes tailored to your type of project.
Helical Projects & Solar
Engineered helical piers for solar arrays, pre-construction foundations, and large-scale pier projects.
Multi-Family Buildings
Apartments, condos, and townhomes: foundation, drainage, and structural repair without losing tenants.
General Contractors
Subcontract foundation, helical pier, slab lift, and concrete leveling work for GC partners across the region.
Agriculture & Industrial
Barns, livestock buildings, equipment pads, and soil stabilization. Built for ag and industrial site conditions.
Property Managers & Realtors
Pre-listing evaluations, deal-blocker repairs, and warranty paperwork that closes the buyer's concern.
Structural Engineering Support
Stamped drawings, torque-test data, carbon fiber spec, and slab lift design, coordinated with your engineer of record.
Commercial Services
What we are called out for.
Five commercial services, in the order Brian Dalinghaus ranks them. Each page is written for the general contractor, owner representative, or facility team who has to decide what to do, and each one says who designs the repair and who installs it.
Helical Piers for New Construction
Deep foundation support under new commercial footings, equipment pads, and solar and battery structures, installed to the engineer of record.
Solar Carport Helical Piers
Foundations for carports, canopies, ground mount arrays, and battery storage, phased around a parking lot that has to stay open.
Polyurethane Injection for Roadways and Municipal Work
Lifting, void filling, and soil densification for roadway panels, sidewalks, and municipal concrete, with same working day return to service in most cases.
Tilt-Up and Warehouse Foundation Repair
Underpinning, slab stabilization, and crack repair on tilt-up buildings and distribution facilities, phased around racking and dock traffic.
Commercial Slope Remediation
Helical tieback anchors and wall stabilization on commercial hillside sites. Scope is still being confirmed with the client.
The methods behind these scopes are explained at house scale elsewhere on the site: how helical piers carry a load, deep polyurethane injection, and tieback anchors against lateral soil load. If the building is already moving and nobody agrees by how much, a documented commercial inspection is where this usually starts.
Commercial foundation repair, explained by the people doing it.
DCI's own overview of what commercial work involves: why the footings are a different animal from residential, what causes the movement we are called out for, and who decides the repair.
What Makes Us Different
This isn't a residential call gone bigger.
Commercial work is a different discipline. Different documentation requirements, different scheduling constraints, different consequences when something goes wrong. We've been doing it since 2011.
Stamped engineering on every job that needs it.
Helical pier drawings, torque-test data, and slab lift submittals, produced for the engineer of record, not against them. Permit cycle stays clean.
Project-scale crews, residential discipline.
The same crews that have completed more than 2,000 projects show up the day they said they would, document the work daily, and clean the site before they leave.
Realistic schedules, written proposals.
No verbal commitments. The proposal is the contract, and any change to scope is a written change order signed before the work it covers.
Eight offices across California and Arizona.
Crews mobilize from Lake Elsinore, Irvine, Westlake Village, La Mesa, Carlsbad, Phoenix, Prescott, and Flagstaff, so commercial projects anywhere in our CA, AZ, and NV footprint get local response.
Licensed in all three states we work in.
CSLB #983851 in California, ROC #330307 in Arizona, and #0089738 in Nevada. The California license carries four classifications: A General Engineering Contractor, B General Building Contractor, C-8 Concrete, and C-61/D30 Pile Driving and Pressure Foundation Jacking. C-61/D30 is the classification the state issues specifically for the underpinning and pressure jacking scope, so the qualification your prequal package asks about is already on file with the board.
How Commercial Projects Work
Four steps. Nothing left ambiguous.
Every commercial engagement follows the same sequence, from first contact to written proposal to execution. No verbal commitments, and no scope change without a signed change order.
- 01Site walk + scopeWe meet on-site with the GC, owner, or engineer to understand the failure mode and the design intent.
- 02Written proposalLump-sum or unit price, drawings stamped if required, schedule with start and finish dates.
- 03Mobilize + executeCrews show on schedule. Daily progress photos. Torque-test data captured live for permit records.
- 04Documented closeoutAs-builts, load data, warranty paperwork delivered with final invoice. Nothing left ambiguous.
