Cookies from social networks allow you to share our site's content and your opinion on it with others, e.g. "Share" and "Like" application buttons, from social networks such as Facebook, Twitter, LinkedIn, Viadeo, etc. The social network which supplies these application buttons can identify you using this button, even if you have not clicked on it while browsing our site. This is because some cookies allow the social network concerned to track your browsing of our site if the social network is activated on your device while browsing our site.

We have no control over the processes used by social networks to collect information about your browsing of our website. Please check the relevant social networks' personal data protection policies. These give you certain confidentiality options in relation to social networks, particularly by configuring your account settings with each network.

The length of time third-party cookies, such as cookies from social networks, are retained can be amended at any time before Lafarge receives the information. Once Lafarge has been informed, changes to duration will be indicated within this policy.

If you have blocked all or some cookies, it is possible that the website will no longer function correctly or that you will not have access to some parts of the site, for which we cannot be held liable.

Updates to the cookies policy
