Terms of Use

By using this website, you agree to these terms. If you do not agree, do not rely on or use the site’s content or enquiry functions.

General technical information

The website provides general educational and technical information. It is not a substitute for project specifications, material supplier instructions, laboratory testing, inspection, professional judgement, or approval by the responsible project parties. Concrete materials and performance vary with source, proportions, production, environment, testing, placement, curing, and exposure.

No professional engagement through site use

Reading content, sending an email, or submitting a form does not create a consultant–client relationship, duty of care, exclusivity, confidentiality agreement, or obligation to accept or respond to a project. An engagement exists only when scope, responsibilities, deliverables, limitations, fees, confidentiality, and other applicable terms are agreed in writing.

Responsible use

You are responsible for checking the information against current project requirements and authoritative sources. Do not submit unlawful content, malicious code, confidential information you are not authorised to share, personal data about others, or material that infringes another party’s rights.

Standards and external references

Standards, codes, and guidance may be revised. References are provided to help identify relevant source material; the current official publication and project requirements must be checked. External websites are controlled by their respective operators.

Copyright

Unless otherwise stated, original site text, diagrams, and presentation are protected by copyright. Brief quotations and links may be used where permitted by law and with appropriate attribution. Republishing substantial content, removing attribution, or using site material to imply endorsement requires written permission.

No warranty

The site is provided on an “as available” basis. Reasonable care is taken in preparation and review, but completeness, uninterrupted availability, and fitness for a particular project are not guaranteed.

Limitation

To the extent permitted by applicable law, responsibility is not accepted for loss arising solely from reliance on general website content without the project-specific checks, testing, approvals, and professional review the situation requires. Nothing in these terms excludes a responsibility that cannot lawfully be excluded.

Changes and contact

Content and these terms may be updated. The effective date identifies the current version. Questions may be sent to contact@hosseinbarzegar.com.
