Walgreen's Slabs
Anyone know what the thickness of a Walgreen's slab is? I'm assuming they are all built alike, but then thats assuming. Theres no way I am drilling all the way through this baby. The vct has glue seeping through the seams.

RE: Walgreen's Slabs
We used to do a lot of Sports Authorities and a lot of Rite Aids.

You can never be sure. It is an issue I always have. I usually assume 4" slabs UON. And specify that is the assumed thickness Unless Otherwise Noted.

Put it back on the owner of the building (usually not walgreen's) to dig into records.

RE: Walgreen's Slabs
Yea, maybe I should drill all the way through then...sigh. I'm only dealing with a store manager, and a flooring/janitorial service. I doubt either one knows.

I better bring along some corks in case I hit water.

RE: Walgreen's Slabs
I'd just drill it. A 1/2 inch hole is all you need, then stick a wire with a hook on the end in the hole and feel for the bottom. The antenna from a '68 Barracuda works the best.

You can fill the hole with two part epoxy, or to save money crumple up a couple of $20 bills to stuff in the bottom of the hole then use epoxy. Drill the hole in an out of the way place so if it ever morphs into a geyser you won't have a problem on your hands.

RE: Walgreen's Slabs
Hmmmm, Thats going to be noisy and more time consuming. You guys ever do them in stores that are open? I'm thinking I better do it before it opens. But man thats pretty early for me. ZZZZZZZZZ

You can be through that slab in under a minute... I've done it in hospitals above operating rooms. I figure by the time they can get the maintenance guy alerted and he can find me, I'm long gone.... Big Grin

RE: Walgreen's Slabs
Maybe I'll just drill it for a normal 4 inch slab since the floorcovering is already in place and the rh has already equillibrated, eh? I should get a decent reading in a couple days.Confused

RE: Walgreen's Slabs
If you do 4" and it comes in high you know the only way it is a false 'high' test is if the slab is less than 4". Per Jason's post re: what will give a false positive. (a hole drilled too deep was one example, along with aggregate etc..)

RE: Walgreen's Slabs
Yes, there's no way a commercial slab is less than 4" in depth.
