Concrete Foundation Construction & Repair
Serving Walnut Creek & Surrounding Areas
Comprehensive Foundation Services
From engineered design to precise pours
De Lira Concrete Corporation delivers end-to-end foundation solutions for residential, multifamily, and light commercial projects. Our licensed team coordinates closely with structural engineers and geotechnical consultants to design, form, reinforce, and pour foundations that meet current codes, project specifications, and performance goals.
We manage site preparation, excavation, formwork, rebar placement, embed coordination, anchor layouts, and high-strength concrete pours with strict quality control. From vapor barriers and insulation to finishing, curing, and documentation, we produce flat, true, and durable foundations ready for framing on schedule.
Tailored systems for your structure
We build slab-on-grade foundations (including post-tensioned systems), raised perimeter stem-wall and crawl-space foundations, thickened-edge monolithic slabs, mat (raft) foundations for heavy or distributed loads, and grade-beam systems supported by drilled piers or caissons to bridge poor soils or spans.
Where conditions demand, we incorporate stepped footings for slopes, deepened frost-protected edges, shear keys, and seismic hardware. Options include integral moisture control, rigid foam under-slab insulation, termite barriers, and sustainable mix designs with supplementary cementitious materials for reduced carbon impact.
Lasting fixes backed by engineering
Foundation issues often show up as cracked walls, sloping floors, gaps around windows and doors, or uneven slabs. We perform a thorough assessment—elevation surveys, crack mapping, soil probing, and drainage evaluation—to identify root causes and develop a stamped repair plan when required.
Stabilization methods include underpinning with push piers or helical piles, slab lifting and void filling with polyurethane foam, epoxy or polyurethane crack injection, carbon-fiber reinforcement, and grade-beam extensions. We restore structural capacity while minimizing disruption to landscaping and finishes.
To prevent recurrence, we address water and movement: perimeter French drains, downspout management, re-grading, waterproofing membranes, vapor barriers, sump systems, and improved sub-slab drainage. We also perform seismic retrofits—bolt and hold-down upgrades, shear transfer improvements, and cripple-wall bracing.

Local Expertise and Project Process
What to expect when you work with us
Our process starts with an on-site consultation in Walnut Creek to review plans, evaluate soils and access, and capture elevations. We handle permit coordination with Walnut Creek building officials, align with local inspection milestones, and, when needed, arrange geotechnical reporting compliant with Walnut Creek requirements.
During construction in Walnut Creek, we maintain clear schedules, daily updates, and careful logistics for narrow streets and hillside lots common in the area. We follow Walnut Creek noise, dust, and haul-route guidelines, protect neighboring properties, and recycle demolished concrete at approved facilities.
Upon completion, you receive as-built documentation, care guidelines, and a workmanship warranty tailored to Walnut Creek conditions. Our foundations are engineered for local seismic demands and expansive soils, and our team remains available for post-storm checks and responsive service throughout Walnut Creek.
