Is there any information available concerning the performance of post installed concrete anchors in building slabs near or adjacent to sawcut joints vs full depth expansion/contraction/control joints?
For example are there any guidelines, technical details or testing data available to use as a guideline for minimum distances from Sawcut Joints vs Full Depth Joints.
- Are they treated the same or differently in Anchor Design
- Expansion, Adhesive & Undercut Anchor Types Specifically
- Are there any exclusions that would apply to Anchor Performance on one vs the other
- Are there any reference materials, whitepapers or testing data you have that would be good training materials
Hi Ralph,
Hilti does not have testing of its anchors next to saw cuts or other types of slab joints.
Installing too close to a joint could risk cracking or spalling of the concrete. Because of this, engineers typically consider control joints as an edge as a conservative approach.
Ultimately, all design decisions are at the discretion of the Engineer of Record (EOR) on the project. The engineer on the project should consider engineering judgment and on-site evaluation to verify the connection.
