DMCA Policy

Last updated: 2026.

ConcreteInfo Media LLC respects copyright and responds to valid notices under the Digital Millennium Copyright Act, 17 U.S.C. § 512. This page explains how to send a takedown notice, how to counter one, and what happens after each.

Designated agent

Send copyright notices to:

DMCA Agent, ConcreteInfo Media LLC Email: [email protected] Subject line: DMCA Notice

Email is the fastest route and the one we monitor. If you need a postal address for service, request it at the address above and we will provide it.

Notices sent to this address should concern copyright only. Correction requests, accessibility reports, licensing questions and press inquiries go to the same inbox but should use the routes described on our contact page so they reach the right person.

Before you send a notice

Two things are worth checking first, because they resolve a large share of complaints without a takedown.

Are you asking about our use of a standard, brand or color name? We summarize the scope and purpose of ASTM, ACI and similar documents in our own words and link to the publisher. We do not reproduce their text, tables or numeric limits. Manufacturer, product and color names are used as editorial reference for identification and comparison, which is nominative use, not a claim of affiliation or endorsement.

Would a correction or an attribution fix it? If we have quoted you too generously, credited you incorrectly, or missed a citation, email us and say so. We will usually fix it within days, and that is faster than a formal process for both of us.

Also note that 17 U.S.C. § 512(f) makes a person who knowingly materially misrepresents that material is infringing liable for damages, including costs and attorneys’ fees. Fair use is a legal right, and you must consider it in good faith before sending a notice.

Elements of a valid DMCA notice

To be effective under 17 U.S.C. § 512©(3)(A), your written notice must include substantially all of the following:

  1. A physical or electronic signature of a person authorized to act on behalf of the owner of the exclusive right that is allegedly infringed.
  2. Identification of the copyrighted work claimed to have been infringed — or, if multiple works at a single site are covered by one notice, a representative list of those works.
  3. Identification of the material that is claimed to be infringing or to be the subject of infringing activity, and that is to be removed or access to which is to be disabled, with information reasonably sufficient to permit us to locate it — please give the full page address on concreteinfo.shop and quote or describe the specific passage, image or table.
  4. Information reasonably sufficient to permit us to contact you, such as an address, telephone number and, if available, an email address.
  5. A statement that you have a good faith belief that use of the material in the manner complained of is not authorized by the copyright owner, its agent, or the law.
  6. A statement that the information in the notification is accurate, and under penalty of perjury, that you are authorized to act on behalf of the owner of an exclusive right that is allegedly infringed.

A notice that substantially fails to comply with these requirements may not be effective. If your notice is incomplete, we will tell you what is missing so you can resubmit.

What we do when we receive a valid notice

  1. We acknowledge receipt, normally within 3 business days.
  2. We expeditiously remove or disable access to the material identified.
  3. We notify the person who posted the material, where that is someone other than us, and provide them a copy of your notice.
  4. We tell you what we removed and when.

Where the material is our own work, we may respond with the basis on which we believe the use is authorized or lawful rather than remove it — and we will say so clearly and promptly rather than ignore you.

Counter-notification

If your material was removed and you believe the removal was a mistake or a misidentification, you may send a counter-notification under 17 U.S.C. § 512(g)(3). It must include substantially all of the following:

  1. Your physical or electronic signature.
  2. Identification of the material that was removed or disabled, and the location at which it appeared before it was removed or disabled.
  3. A statement under penalty of perjury that you have a good faith belief that the material was removed or disabled as a result of mistake or misidentification.
  4. Your name, address and telephone number, and a statement that you consent to the jurisdiction of the Federal District Court for the judicial district in which your address is located — or, if your address is outside the United States, for any judicial district in which ConcreteInfo Media LLC may be found — and that you will accept service of process from the person who provided the original notification or an agent of that person.

Send it to [email protected] with the subject line DMCA Counter-Notification.

If we receive a valid counter-notification, we will forward it to the original complainant and inform them that we will restore the material in 10 to 14 business days, unless they notify us that they have filed an action seeking a court order to restrain the allegedly infringing activity. Bad-faith counter-notifications carry the same § 512(f) liability as bad-faith notices.

Repeat infringer policy

We terminate, in appropriate circumstances, the accounts or access of anyone who is a repeat infringer, consistent with 17 U.S.C. § 512(i).

This site has no user accounts and does not accept user-submitted content, so in practice the policy applies to contributors and to any future submission channel. A contributor who supplies infringing material more than once will not have further work published here, and we will re-review everything they previously supplied.

The content of this site — text, page structure, tables, calculators, illustrations, code and the compilation of data — is owned by ConcreteInfo Media LLC and protected by copyright. If you find our work republished elsewhere without permission, we would like to know: email [email protected] with the address. Permitted uses and how to request permission are set out in our terms of service.

This page describes a procedure. It is not legal advice, and we cannot advise you on whether a use is infringing or fair. If you are unsure, talk to a lawyer.
