Grace I&WS at perimeter, ridge and penetrations. Felt underlayment over the field. Why put essentially a vapor barrier over the full roof and risk wood deterioration due to condensation? Unless the slope is less then 5:12 I would not cover the full deck with I&WS. And I have yet to see an...

FWIW, the 'window pane test' hasn't been considered a reliable test in the commercial floor coating/ covering industry for several years now...

There is no hard and fast rule as to how long the concrete will take to dry sufficiently. Running A/C, etc. may dry out right at the surface, but moisture will still be a little deeper in the concrete, which could lead to coating failure. I am guessing you did not test prior to washing the...

Honestly I would not cover the whole thing with I&WS. It is a pretty effective vapor retarder, and full coverage increases the likelihood of condensation forming within the sheathing, leading to deterioration of the deck. I have seen this in both residential and institutional applications over...

eh, saying that is like calling steel 'carbon'. It's only one part of the recipe... Congrats on the slab pour -- that is a great sense of momentum.

Saw a rep today. They have a smaller, circular light that is pretty cool. It's mainly interior, but rated for 'damp'. Can control light color and intensity. Pricing was $150 - $200 per fixture depending on finish (white was $150). 4 of those in a residential garage might be better then 1 or...

:thumbup:

'soft spots' usually mean the subbase or subgrade is failing. Whether you just patch the paving system or do an overlay you should to cut out these areas and do 'full depth patches' that include recompacting the subgrade, and restoring the subbase and full thickness of asphalt.

The fiberglass is for crack control, shrinkage reduction and increased toughness more so then for 'strength'. Those fibers take the place of the shrinkage control steel (i.e., the wwf in a slab-on-grade)

fiber reinforcing strands? I've seen them get burned off by lightly hitting with a torch.

That's what happens when you just use cement instead of concrete ;-)

Tremco's TREMproof GC250 membrane is roller/ brush applied -- much easier then spraying. Not many things will work well over moving cracks though. Isn't the concrete reinforced? That really should limit the ability of cracks to open/ close... You really need to treat moving cracks with...

Curling happens, unfortunately. What was the consensus on why it was so severe in this case, though? It is pretty normal to need to grind at least some of the slab edges before putting the slab into service in a warehouse environment.

That was a nice write-up, Vintage. It also should be noted each increase in the F# results in a big jump in cost. And many/ most concrete contractors will not be willing to tackle the flatter floor requirements. You really do need a specialized concrete guy, and then you need to convince them...

Not normal to dowel a slab-on-grade to foundation walls.

Welcome, from Alexandria. I'm waiting for Dudley to finish his garage so he can come over and help enclose my carport.

This saw cutting and chipping down high spots within the area to receive the patching mortar is SOP for the concrete repair industry, and is critical in the long-term success of the patch.

GypCrete is the most common name. Also, some people refer to that type of material as "foamed concrete"

In that second post it may have been a self-leveling gypsum concrete mix, which is normally used prior to installing an actual floor finish such as wood flooring or carpet. the material is too soft to be left as a finished surface.

Would need to know more info about the OP's garage. In the world of single-ply membranes, TPOs stand out because the early manufacturers latched onto the reflective benefits, which resulted in a lot of architects specifying those systems. TPOs are no better performance-wise then other...
