Grooved Concrete - DF

Dana Zaichkin

If I recall from your original post, wasn't this a really thick slab and the underfloor predominantly for tile warming?

Some projects I say I wish I never started, swear I'll never do again, but seem to anyway.

Wow

Here are some pics of the grooved concrete job I posted questions on several weeks ago. The architect dictated that there were to be no thresholds between the kitchen remodel, the addition and the existing home. Due to the thickness of the finish floor (marble) we had to groove the concrete to keep within the required floor thickness. A thin leveling mudset will be set over the piping and existing structural concrete slab before the marble is laid.

We grooved the concrete using a gas powered concrete saw to make two parallel cuts. We then chiseled out the groove with a rotary powered chisel. The only way to secure the pex tightly was to use emt straps and anchors. All in all, it was very labor intensive (two days) and no fun! I'm not sure I will try this again. -DF

Good Job Dan. I'm sure they hired your company because they knew you'd get the job done, one way or tuther.

See you this weekend.

What about

using Onix for this application, could have gotten away without using any straps?

Onix

We considered Onix but the diameter of the hose is considerably bigger than the 3/8" pex which would have necessitated a wider, deeper groove in the concrete. No go. -DF

first off dan

thanx for sizing the pictures just right. unfortunately i am back on dial-up, so i don't look at too many pics anymore.

had similiar but different experience once. went to lay the loops for a slab on grade. the builder had poured the "first" lift of concrete we had to snap every loop line out first, then like you, had to attach to the concrete.

i feel your back pain brother!

looks like a top-knotcher again dan!
