Silo Repair in Iowa — Welds, Hatches, Valves & Coatings | Ames Hydraulics

A cement, fly ash, or feed silo that’s leaking, cracking, or has bad discharge hardware is a storage asset that stopped being trustworthy. Ames Hydraulics does silo repair in central Iowa on cement, fly ash, lime, feed, and other dry-bulk silos of every make. Welded structural work, hatch and manway hardware, discharge valves, coatings, and pneumatic plumbing. Free jobsite visits within 60 miles of Ames.

What Actually Fails on a Silo

Most silo repair falls into a few reliable buckets. Cracked welds show up first — at the cone-to-cylinder joint, at the manway and hatch openings, and at the legs where the silo bolts to the pad. Hatch and manway hardware wears from being opened and closed thousands of times and eventually stops sealing. Discharge valves — butterfly valves, slide gates, and rotary airlocks — leak or stick and stop metering product correctly. And coatings on the outside eventually fail from weather and need touch-up before rust does structural damage.

What We Repair

• Cracked welds at cone-to-cylinder, manway, hatch, and leg joints — welded and reinforced to code
• Hatch and manway hardware — gaskets, hinges, latches, and sealing surfaces
• Discharge valves — butterfly valves, slide gates, and rotary airlock feeders
• Pneumatic fill lines and product plumbing
• Vent hardware and pressure/vacuum relief
• External coating repair and touch-up
• Leg reinforcement and structural welded fixes at the base
• Internal cleaning access when a repair calls for it

Cement, Fly Ash, Feed, and Additive Silos

Different products fail silos in different ways. Cement is abrasive and eats discharge valves and airlocks. Fly ash is finer and gets past bad seals in ways cement doesn’t. Feed silos deal with moisture, mold risk, and USDA cleanliness rules. Additive and catalyst silos are usually smaller flow-bin-style units with their own hardware. Silo repair here is done to the standard the silo was built to and the service it’s in — not one-size-fits-all.

Welding Is the Reason Most Silos Come to Us

Silo silo repair is largely welded structural work — and welded structural work on a pressure- or vacuum-cycled vessel calls for a shop that does structural welding to code every day. That’s why silos come here rather than a general contractor: we can weld carbon steel, weld aluminum where a silo is aluminum, and document the repair to your maintenance records. Cracks get chased to their real end (not just filled), reinforcement plates are sized correctly, and the welded joint is prepared properly so it holds.

On-Site or In-Shop

Most silo repair is done on-site — a mounted silo isn’t coming off a pad for a valve rebuild. We come to your yard or plant with the welder and the parts. Smaller portable silos and flow bins can come to our shop if that’s easier. Free site visits within 60 miles of Ames.

Do It Before the Winter Refill

The right time for major silo repair is before your silo goes back into heavy use — typically late fall for ready-mix and precast operators before winter blending, or in the shoulder seasons for feed operators between harvest and heavy delivery. Repairs done on an empty silo cost less and turn faster than emergency work on a full one. Schedule ahead if you can.

Compliance and Documentation

Silos serving regulated industries — food, cement kilns, ag processing — often need documented repair for compliance records. We provide written repair documentation, photos before and after, and welding-procedure paperwork when the job calls for it. Tell us up front what you need.

Related Equipment

Silos rarely stand alone. If you’re getting a silo repaired, it’s often the right visit to check the blower, dust collection, and flow bins that go with it. See the dry bulk blower, dust collector, and flow bin pages. New replacements for anything past repair are available — see the cement silo sales page.
