The John Alonso Guarantee
STRUCTURAL WORK DONE RIGHT. EVERY TIME.
WHY FRESNO BUSINESSES TRUST JOHN ALONSO FOR STRUCTURAL CONCRETE
For more than three decades, John Alonso has helped property owners and contractors tear out bad concrete and replace it with foundations they can build on. We plan the sequence of demo and pours so your project stays on schedule and trades are not tripping over each other. Old slabs are removed down to sound material, sites are graded and compacted, and new foundations are formed and poured to spec so the rest of the work has a solid start.
We are not satisfied until your old concrete is gone and your new foundation is ready to build on.

Fresno’s Foundation Work & Demolition Contractor
John Alonso Concrete handles foundation work and concrete demolition for commercial, industrial, and larger residential projects across Fresno. We excavate, form, reinforce, and pour new foundations, and safely remove old slabs, footings, and flatwork that are in the way of your next phase. From small equipment foundations to full slab replacement, we keep your site moving forward and ready for construction.
Why Fresno Businesses Choose John Alonso For Foundations & Demo
With 31+ years in the field, John has supported shops, plants, warehouses, and contractors with both new foundations and selective concrete demolition. We understand how to tie new pours into existing structures, protect nearby utilities, and keep critical areas open while work is underway. Our crew brings the right saw cutting, breaking, and removal equipment so you get a clean, ready‑to‑build surface instead of a mess you have to fix later.
Honest Pricing. No Guesswork.
Every foundation or demolition scope is priced around actual conditions—depth, access, thickness, reinforcement, haul‑off, and site constraints. You see line items for excavation, demo, removal, forming, rebar, and concrete, not just a lump number. That way you know exactly what is included before we start, and you are not hit with surprise extras halfway through the job.
