The ACT Group cleans silos, bins and hoppers across Los Angeles County — the cement terminals at the ports, the batch plants along the 605 and the 5, the aggregate operations in Irwindale and Sun Valley, and the food, feed and recycling plants in Vernon and the South Bay. No confined-space entry, MSHA and OSHA trained crews, and a truck that is about an hour from downtown.
Los Angeles runs on bulk material that most people never see: cement and fly ash arriving by ship at the Port of Los Angeles and Long Beach, aggregate from the San Gabriel Valley pits, flour, sugar, grain and feed moving through Vernon and Commerce, and the ready-mix and asphalt plants that feed every job site in the basin. All of it lives in silos, and every one of those silos eventually bridges, ratholes or loses capacity to buildup. Since 1991 our Fontana crews have been the ones L.A. plants call to get that capacity back — from the top of the vessel, without sending a person inside.
No-Entry Cleaning: The Silo Whip removes bridged and caked material from the top down. No confined-space permit, no standby rescue crew, no engulfment risk — which is exactly what safety-driven L.A. operators and their insurers want to hear.
About an Hour Out: Fontana to downtown Los Angeles is roughly an hour; the ports, the South Bay and the San Fernando Valley are within two. Emergency calls are same-day, and planned cleanouts fit inside a normal shutdown window.
Customers You Know: Our silo and bulk-handling customers include Cemex, CalPortland, Granite Construction and Rio Tinto, plus terminals, batch plants and food processors across the basin that we are glad to name over the phone.
Silo, bin and hopper cleaning: Cement, fly ash, slag, lime, aggregate fines, flour, sugar, grain, feed and recycled material removed from the top with the Silo Whip — any vessel diameter, steel or concrete.
Port and terminal work: Import cement and fly ash terminals with strict throughput schedules get planned cleanouts timed between vessels.
Batch plant and asphalt plant silos: Aggregate, sand and cement silos at ready-mix and hot-mix plants, cleaned around the pour schedule.
Food, feed and processing plants: Flour, sugar, starch, grain and feed silos cleaned with the sanitation practices those plants expect — and no worker in the vessel.
Emergency response, 24/7: A plugged silo shuts down everything downstream. Call (888) 480-0680 and a crew is moving from Fontana.
Flow aids after the cleanout: Air cannons, vibrators and liners installed while the silo is empty so the buildup stays gone — see air cannon service.

Los Angeles County plants operate under the South Coast AQMD, with the Antelope Valley under its own district. A top-entry cleanout with the vessel sealed and dust-controlled keeps the job from becoming a fugitive-dust complaint under Rule 403. We plan every cleanout around your permit conditions and your neighbors.
Plugged silo, shrinking capacity, or a terminal cleanout to schedule between ships? Call and we will give you a real window — and since 1991, we have kept them.

Port terminals, batch plants, food silos — cleaned from the top, nobody inside
Bridged material looks solid until it isn’t. Traditional silo cleaning puts a worker on the pile or in the vessel; the Silo Whip does the same job from an access hatch on the roof. For Los Angeles plants with strict safety programs, union crews and city inspectors, that difference is the whole conversation.
Air cannons, vibrators and liners installed while the vessel is open, on the same visit and the same quote.
About an hour to downtown, the San Gabriel Valley and the Gateway Cities; roughly ninety minutes to the ports, the South Bay and the San Fernando Valley. Emergency calls are same-day and we answer 24/7 at (888) 480-0680.
Yes. We clean import cement and fly ash terminal silos on schedules timed between vessel arrivals, with the badging, safety documentation and insurance certificates terminal operators require.
Yes — flour, sugar, starch, grain and feed silos in Vernon, Commerce and across the basin. Because nobody enters the vessel, contamination risk is lower than with manual cleaning, and we follow your plant sanitation requirements.
Same crew, same dispatch. Anaheim, Santa Ana, Irvine and the rest of Orange County are about an hour from Fontana and covered on the same terms as Los Angeles.
