The photo's below show 2" of DOW High-load 40 underneath the slab, and 2" of 25psi stuff from Lowes on the sides, with a 3/8" plastic piece glued to the top of it. An engineer who was over today doesn't think it's going to buy me much, and will be a maintenance item. He suggested I just use...

We're just about done with our garage project, and are thrilled with way it's turning out... However, we just poured the section that is insulated in the photo and, in trying to match the existing driveway, picked a color that is too purple. I think we're going with what we believe is the...

I've got my snowmelt PEX laid and I'm now wondering if the driveway is going to be thick enough to avoid cracking. The pour is scheduled for Tuesday, so I've got to figure this out quick. On top of 2" of DOW High Load 40 EPS, I've got 10ga mesh with 3/4" (.875" outside diameter) PEX...

This stuff is really stiff!! How can I bend it so I've got it laying on 12" centers? It's standard 3/4" BPEX from Infloor. I've got a guy coming to lay down the PEX for my snowmelt system tomorrow, so I need a quick answer! Thanks!! Mark

I'm looking for some sort of insulation to put between the part of my driveway that will be heated (snowmelt system) and the part that will not, as well as for the edges of the slab that are bounded by soil. Anyway, I found this insulating the edges of an outdoor ice rink: It worked great...

Would it be possible - from a code and engineering perspective - to drill a 4" or so hole into an existing footer that supports a 1080sf garage? While not sleeping tonight, I was trying to figure out a way to drain my driveway in the winter, without having to heat the entire 12' wide slab...

I just learned that my contractor is planning to pour the slab directly onto the soil (with perhaps an inch or so of road base just for leveling purposes). he said the soil was virgin - in that it wasn't fill dirt - so this was OK. Is it? I'm putting in an in-ground lift and hydronic heat, so I...

I'll be using 2" EPS under the garage floor slab, but I need to heat about 1400sf of driveway in front of it. What insulation should I use there? How would I insulate the sides of the driveway, since they'll be exposed to dirt, grass, bugs, etc? Thanks, Mark

I'm about to have the final grade done in our 32x34 garage with a floating slab. The slab will be 6" thick, with in in-ground lift in the (more or less) middle, and hydronic radiant heat. I'll routinely park an 8000lb Excursion on it as well as other 5000lb vehicles. So, do I need the Dow...

Our new floor will have PEX loops in it, and I'm planning to build a framed room on it to house the boiler and compressor. How do I attach the base of the wall to to concrete floor? I've done this in the past with a .22 powered nail gun, but that doesn't seem to be the right idea in this case...

Without drilling a well? I'm putting in an in-gound lift, but the outfit I'm buying it from called the other day to find out if I knew if the water table was near the 9' depth of the hole we'll have to dig. If it is, they won't install, but I'm still stuck with the lift. So, I'm trying to...

When the framers showed to to frame the garage, the first thing they did was cut off *all* the rebar sticking up out of the footers, including the Ufer ground. How can this be fixed? Could I just weld a piece of rebar onto the now-flush-with-the-footer end of the ground? Or would it be better...

I'll soon have the floor poured in our new 32x34 garage, but I noticed tonight that there is still some sod lying just below the surface of the dirt floor that's there now. I'm thinking that should be removed before the gravel is brought in, right? Wouldn't the grass eventually decompose...

What are the real differences between a "3000lb" pour and a "4000lb" pour? I understand that one is stronger than the other in a given thickness, but why? What are the downsides to a stronger poor? (Why do weaker pours exist?) I'll soon have my 32x34 garage floor poured, and expect it to have...

What's an in-ground lift like to live with when it's not in use? Are there clever ways of allowing you to drive over the arms and center section (which isn't rated for vehicular traffic)? I'm thinking of putting a Rotary in-ground lift in the garage we're building, but it's going to have to go...

They're pouring the stem walls of our new 32x34 attached garage this week, and we'll be using radiant in floor heating when the time comes. I found a document (linked below) that appears to suggest putting 2" insulation on both sides of the stem wall. What does that buy me? I'd planned to...

VCT: Does it work OK for a garage with a heavy vehicle? I've pretty well decided to go with VCT tile for for the floor in our new garage, but I have a question: Is VCT an appropriate choice for a garage that stores a heavy vehicle? I've got an 8000lb Excursion, and I don't want to have to...

I figured this would have been asked before, but I couldn't find the answer, if it has... Can a gas line be run up from the meter then into an attic space to run the length of the house? My meter is on one of the new house, and the garage will be on the other. Extending an existing line means...

I searched this forum for the word "value" and got zero hits. Not good... I've been busily researching flooring options here, and it looks like any epoxy or poly DIY option would be in the $1800 - 2500 range (1000sf new slab) and hiring it done would double the price, and might increase...

I've decided to put radiant floor heat in the new garage, and would love to see pics of how the tubes connect to the boiler. I don't have a mental image of how this part works, how much room the boiler will take up, etc. Let's see 'em! I'll be heating roughly 1000sf of slab, plus another 500sf...
