Clean concrete rules stop at the steel
Many sites accept cured concrete without steel as inert rubble and send reinforced pieces somewhere else, or they accept both but only in a mixed bay. Call and say the concrete has rebar or mesh still in it. Ask about piece size and about whether the steel must be cut flush or may stick out. Do not describe the load as clean fill. A single hidden bar is enough for an attendant to reject a whole truck. If you can separate the steel safely with the tools and skill you have, the concrete and the rebar may then follow two paths: inert rubble and scrap metal. If you cannot separate them, haul the chunk as mixed reinforced concrete to the bay that allows it. Do not torch the bars in a plastic bin, and do not smash concrete on the tipping floor.
Ends of bars are a handling hazard
Rebar that sticks out of a chunk will cut a strap, a tire, and a person. Cap or tape the ends, and load the pieces so the bars do not point at the cab. Keep the weight low and against the cab. Reinforced concrete is denser than household trash of the same volume, and a small pile can overload a half-ton truck. Make a second trip rather than stacking above the rails. Wire mesh in a sidewalk slab counts as steel. So does a post base. Flick a magnet or look at the broken face before you call the load clean. Dirt clinging to a footing is a third material. Knock it off if the inert bay requires clean concrete.
Say mixed before the scale house asks
Tell the attendant you have reinforced concrete so they can point you at the right pile the first time. Unload where they say. Do not pitch a chunk with a bar sticking out into a pile of people. If the site refuses mixed material, take it with you and use the facility they name. Do not break the bars off against the bay wall. Sort any loose cutoffs into the scrap container only if staff said that container is for loose steel. A bar still buried in concrete is not loose scrap. Sweep chips back into the pile you were assigned so the lane is clear.
Before you go
- Call and describe the load as concrete with rebar, not as clean fill.
- Tape sharp bar ends and keep them from pointing at the cab.
- Stay under the truck's payload, and plan a second trip if the chunks are dense.
- Unload only in the mixed or reinforced bay the attendant assigns.
Burying a rebar end inside a pile you told the scale house was clean concrete.
Questions people ask
Does wire mesh count as rebar?
Yes for sorting purposes. Tell the site the slab has mesh. Do not call mesh-reinforced concrete clean.
Can I cut the steel at the site?
No. Do any cutting at home, with the skill and safety gear you have, and only if the site told you separated materials are what they want.
