A:  Hi RAS1, this is Colin from Simpson Strong-Tie. The ABA Adjustable Post Bases are designed to be attached to a concrete footing. Although the terms cement and concrete are often used interchangeably, cement is actually an ingredient of concrete. There are several options for anchorage including our mechanically galvanized Titen Heavy Duty Screw Anchors. Please visit our website at www.strongtie.com. and key THDMG in the search box for more information. Or if you'd like to speak with one of our Customer Service representatives, please contact the Simpson Strong-Tie Customer Service team at 800-999-5099. We look forward to hearing from you.

A:  ​Hi Leon, thank you for your message. We want to make sure we address your question regarding installation of ABA Adjustable Post Base on a 3-1/2" thick concrete slab. To be compliant with out installation minimums a 3-1/2" thick concrete section is not sufficient for any of our anchors or epoxies. Please contact the Simpson Strong-Tie Customer Service team at 800-999-5099 to discuss anchoring options. We look forward to hearing from you.​​ -Stacy

A:  Depends on the number of patio support columns, the reinforcing in the slab, and the support columns under the slab. I used six of them on a 4" concrete slab reinforced with 1/2" rebar on 12" centers. The column anchors were positioned over 8" concrete pillars under the slab. The six anchors are holding 4" x 6" columns supporting a 12' x 17' deck. The deck has shown no signs of movement in the years since it was finshed.
