What moves, what doesn’t, and how people behave.

These never match and never move on DropMaterials. Posting them — or hiding them in a load — gets the account reviewed and usually removed.

• Household garbage
• Treated or painted wood (CCA, creosote)
• Asphalt shingles
• Drywall / gypsum
• Tires
• Contaminated soil (fuel, chemicals)
• Asbestos-containing material
• Invasive plant material

Also prohibited: anything hazardous under federal, state, or local law; anything with a smell, leachate, or pest problem; anything from a site with known contamination; and anything a reasonable person would call trash.

Not sure? Don’t post it. Ask us at support@dropmaterials.com or use the “Other” category with a photo so a recipient can decide with their eyes open.

• Use the closest category. If it’s a blend, say so — “mixed” and “contains soil / leaves” exist for a reason.
• Quantity is approximate, but be honest. Six yards is not twelve.
• Condition tags mean what they say: Clean = one known material. Mixed = compatible materials together. Unknown = you’re not sure, and the recipient decides.
• Fill dirt, concrete, and “other” need a photo before they can match. Photos help everything else too.

• Drop exactly where the recipient marked. Not near it. Not where it’s easier.
• Follow access instructions — gate codes, which way to enter, what not to block.
• Tap “On my way” when you leave and “Dropped” when you’re done so the recipient isn’t guessing.
• If the site doesn’t look right, the gate is locked, or the material isn’t what you thought you had: don’t dump. Report it.
• Don’t dump on a paused or suspended site, or at a site you weren’t matched to.

• List only property you own or have written permission to use for this.
• Know your local rules — fill permits, grading, stormwater, stockpile limits, HOA covenants. They’re on you.
• Keep capacity honest and current. Pause when you’re full or away.
• Keep the drop zone clear and truck-accessible when a load is matched. A wasted trip costs the supplier real money.
• Confirm drops and rate promptly. If something’s wrong, report it in the app rather than in a review.

• Keep people, pets, and vehicles out of the drop zone while a truck is maneuvering.
• Mark overhead lines, septic fields, soft ground, and anything a loaded truck could damage. Say it in the instructions.
• Drivers: no drop is worth backing into something you can’t see. Stop, look, get out if you have to.
• Never ask a driver to dump where the truck could get stuck, roll, or block a road.

• Be straightforward. Both sides are relying on strangers.
• No harassment, threats, discrimination, or retaliation — in the app, at the gate, or in ratings.
• Don’t use phone numbers or addresses from the Service for anything other than the drop.
• Don’t scrape, resell, or republish site or load data.
• One account per person; no impersonating a business or property owner.

Every completed drop asks “Did everything go okay?” Reports cover:

• Wrong material
• Wrong amount
• Dumped in wrong location
• Access blocked
• Recipient unavailable
• Material contaminated
• Property damage
• Unsafe conditions

Reports go to a moderation queue. Outcomes range from a note on the record to warnings, suspension of a site, or removal of an account. Serious safety or property issues are handled first. Reports made in bad faith count against the reporter.
