Hilti 150 MAX or Hilti 150 MAX-SD
Hilti 150 MAX or Hilti 150 MAX-SD
(OP)
I am designing a new building per the IBC 2009. I need to dowel into an existing concrete wall with an adhesive anchor. Can I still specify the Hilti HIT-HY 150 MAX adhesive? Or do I need to use the Hilti HIT-HY 150 MAX-SD?

If you ask Hilti they will probably be willing to have a rep on hand when the first anchors are being installed to monitor the installation procedure.
Adhesive anchors have been used in all kinds of projects, thousands of times, and they are a fine solution for many issues, but they do need to be installed correctly and their limitations should be noted.

Hilti does have a newer specification for the 150 MAX product which permits some uses with uncleaned holes:

We saw quite a bit of incorrect installation during development of the certification program. Experienced installers typically performed as poorly as new ones during trials, so be cautious, and emphasize that written directions should be followed closely until the crews get up to speed.

Max 150-SD can be used under " cracked concrete" condition, while 150 MAX is used under "Uncracked concrete condition".
So, depending upon your situation, you should specify SD or without SD.
