Anchor wall to concrete floor


What is the best way to anchor a 2"x4" wall to a concrete floor in a basement?

Hammer drill and Tap con screws.

This is what I used and they work great.

Thanks for the reply, I actually just saw your response to a similar question in the construction forum. Thanks again, I'll give this a shot.

Easiest way (My vote) = .22 caliber powder actuated fastener.
Some Manufacturer's: Simpson Strongties, Reminton, Hilti....

Use ceramic coated fasteners and number 3 and 4 firing caps....

If you decide to go with the power actuated fastener, you need to wear protection for your ears.

I found it really loud and did not like the smell that it created.

And I guess I did not have the strength to hit it hard enough as I had to try several times before it fired.
(I did not use the trigger type one.)

Good luck.

I gotta go with the 2 3/4" tapcons and construction glue for a wall that will last forever. The powder actuated nails seem to blow apart the concrete once in a while. You never have a misfire with a tapcon. Plus if you move the wall by chance while installing a tapcon, it is much easier to remove a tapcon than a nail that was driven in by a 22 charge. Just my 2 cents.

Thanks for sharing your thoughts.

FWIW - All good points - Your decision does make sense to me...

i recently used a .22 caliber Remington nailer, and the fastener just blew a chip in the concrete floor. since then, i bought some Tapcon screws and a masonry bit.

FWIW: We have experienced this 'blow-out chipping' ..... from time to time on older concrete floors that are mixed very densely, or for what ever reasons ....

Bare in mind, that doesn't always mean that the .22 cal gun is not right for the job.

Just so you know: We have about ten or more powder actuated guns... some are for different applications. We also have a .27 cal and a .30 cal.... for denser materials....
Not every 'gun' is right for 'every' job. It's the same concept of:

A heavy framing hammer is used to drive spikes in.
Vs.
A light finish hammer is used to drive small 'pin' or brad nails in.

Interchanging these 'two tools' will yield far different results....

Thus, 'over-kill' will damage the materials around it....

That is why there are different power cap levels (Levels 1-4), different cal. guns, different length fastener 'pins', different 'style' fastener pins, etc .....

(Just something to realize and think about....)

Anyhow: If you are comfortable with using tapcons, then by all means, go ahead and use those. Use the tools that you are most comfortable with....

What do you do to fine tune your final choice for the denseness of concrete? Do you just nail away till you find the right combination?

Generally, the issue is the power of the cap (when it comes to bottom sills in basments) so:
If we fire it in..... and it's too powerful on the first shot, then we step it down. If it is too weak, then we step it up.
We keep plenty of different power level cap-rounds in each case with the guns so that we have a decent supply that we can pick from.
Cap #3's and #4's seem to be the most common for residential basements....
From time to time, you will get some minor chipping, but generally, that fastener is in there tight.
When we do commercial steel framing, #2's and 1" fasteners are all that is needed.
(That is not to say that we refuse to use any other way of installation. Tapcons are great too - Both the nail anchors and the screw anchors....)

We've never had an issue with the guns. We are currently remodeling 3 basements. Here is a pic of one we did:

Beautiful job Atlantic!

Doesn't really feel like a basement with the walkout.

Thanks for the advice everyone, I ended up going with 2 3/4" Tapcon screws and some Liquid Nails. It worked great. Thanks again!
