Well I just called Tap Con and they told me that the blue Tap Cons are for dry interior use and the gray or stainless steel are approved for wet locations. The wedge anchors are also not to be used for exterior but you can use there stainless steel wedge anchors. the longest ss wedge anchors they make are 3 3/4. They are the Red Head brand that are also made buy the makers of Tap Con.

 

YES!!!

I love it when people take responsibility and reach out to the actual source for information. Great job. You’re the president of your LLC or Inc. company and you have every right to go speak to the president or CEO of any other company or their representatives to get answers.
That’s definitely ”like a BOSS” move.
Great job.

 

Whenever I’ve had to hang a ledger off of block, first of all it has to be fully grouted and have a rebar grid, and then I’ve drilled and epoxied 1/2” all-thread.

Not saying it’s the only way to do it, but I would never use a TapCon in that application, and I certainly wouldn’t use one that short. That would not even penetrate into the block core.

 

A lot of inspectors won't say what to use. No sense in hanging it out now and having it bit off later.

 

Yeah building Dept/Inspectigators won’t tell you how to do it.

You have to say, “I’d like to do this, in this fashion. Will that get approved”?

 

Can you through bolt to the other side, drilling through the CMU joints.

I used epoxy mesh screen tube on the last staircase attached to CMU. Look that up. It's an approved system. May cost $8-10 in material for each hole, (similar to thru bolt) but what's the alternative ?

Worst place to drill/anchor in cmu is through the mortar joint.

 

i didn’t mention that the block was filled solid with concrete where my ledger is fastened. I’m going to remove them and use 1/2” SS wedge anchors.
thanks.

 

I haven't built many decks, but I've demoed more than a few. Wedge anchors would pull right out of the wall with just a little tug of the mini excavator.
I'd prefer epoxy and threaded rod, but some of the new anchors are better than some of the old stuff I've torn out.
Installer makes a difference as well.

 

I had no idea the blue ones were for dry areas. Never seen the other colors.

I had no idea either. They said gray and white are for exterior. I have seen white at Lowe’s.

 

I've used these to fasten a ledger to a concrete foundation.

Stainless-Steel Titen HD®

The Titen HD stainless-steel screw anchor for concrete and masonry is the ultimate choice to provide fast and efficient installation, combined with long-lasting corrosion resistance.

www.strongtie.com

 

The Tapcon[emoji2400] concrete screw with the Climaseal[emoji2400] coating gives excellent rust resistance when used for indoor applications and outdoor applications. Tapcons come in two diameters: 3/16” and 1/4”. The 3/16” Tapcon screw requires a 5/32” hole in the concrete, and the 1/4” Tapcon screw requires a 3/16” hole in the concrete. Each box of 100 screws is packaged with the correctly matched tolerance carbide tipped a concrete bit.

My engineers always call out Titan Bolts for a ledger attachment.

I learned a long time ago to do what the plans and engineering calls out for.

For a short spell epoxy in mess tubes with threaded rod was recognized in the DCA deck guide then it was dropped.
I think through bolting is the only way to do it in hollow CMU.

Inspector's are not legally allowed to advise because then they are taking a design responsibility. Legal stuff. They can say they've seen .......this or seen someone do that....

 

I did use some titan anchors and was impressed. I certainly would not rule those out.

 

The beauty with Titans is there's no outward force on the fastener/concrete like an expansion anchor.

Just the fact that it is going into concrete means it probably is going to have moisture.

The same reason we use Borate for plates.

Haven’t used those Titans yet.

You just drill and set just like an oversized tapcon?

 

Yes with a caveat. The smaller tapcons you drill a slightly smaller hole than the fastener. The 3/8" and above you drill the same size hole as the fastener.

just ordered these. I would have liked to use the Titans because i could have just removed the 3/8 Tap Conns and treaded in the Titans but they are really expensive in SS

Right off their website

That’s interesting. I just ordered SS wedge anchors but I’m going to show that to the inspector. When I called Tap Con they told me blue were for interior or non wet locations. I guess they don’t know about that picture on there website

nicko

 

I would think the inspector would know what he would approve

He does. But most AHJs have rules that prohibit them from giving you advice or direction. It's an awkward situation, but they will refrain from telling you how to do it.

 

It amazes me that so many reps are not as knowledgeable about their own products as the builder is. It happens a lot actually. Makes sense because we more than likely installed much more than they have.

I always thought blue color meant exterior coating .That said it is not a great .Treated wood dissolves it .
Love titans .easy to work with .less problems .Wedge anchors are likely to give me trouble .do not grab sometimes or end up pulling out to much when tightened .I have demoed a few just with a big pry bar . Glue and all thred is what i use in all sismic . I use the 5/32 and 3/16 tapcons or such screws for small stuff .Never structual . I find them to be a pain in the a### .strip out ,jamb and break to much .

 

went online to tapcon websight .i did not see tapcon plus .do you have a link .are they 1/4" or larger

 

Post 29 has the link

 

5.18 Use of anchors must be limited to dry, interior
locations.
I think that even Tapcons picture of using the Tapcon Plus in a ledger board is misleading I found this in their Engineering Approval/Reports.

 

Yup.

No way around the ICC ESR

5.2 The anchors must be installed in accordance with the manufacturer’s published installation instructions and this report. In case of conflict, this report governs.

How can a fastener be used on a warehouse floor without it getting wet.

Or any floor for that matter.
