Early concrete requirements

Hi David,

Hilti anchors are tested into concrete that has cured for at least 28 days. Concrete that has cured for less than 28 days is referred to as green concrete. For information on anchoring into green concrete, please reference Hilti’s Anchor Product Technical Guide Section 2.1.2 on pages 9-10. Click here to access the guide from Hilti’s website. Post-installed mechanical anchors and post-installed adhesive anchors have different considerations, which are both discussed in Section 2.1.2. Typically, site testing is recommended to verify the fastening capacity into green concrete applications.

Best,
Emily
