Thanks all! For me, since it's already an 8" pad, I don't really want to go thicker. The problem areas run almost entirely throughout the pad, edges are the exception, so patches don't make sense. Ideally, I'll have them grind maybe 1/2" off, and polish the aggregate. I like the look of it...

Yeah I'm not arguing that, I never told them to power trowel either... That's why I hired an engineer to spec it, and a company to manage and pour it... This is all new to me! I'm mostly looking for opinions on the best repair that will last, so I can be sure I don't get screwed in a few...

The engineer spec'd the concrete for the job. The GC ordered the trucks, and hired the crew, having inspected the site, and knowing the concrete specs. When I double checked with him on the 5-8%, he answered "That's standard for slabs so yeah, I priced it accordingly. ��" This is...

Thanks, I went through a few first, and this crew came highly recommended! They clearly cared about the job. I was very happy until tonight. I'm also not worried about the strength beyond the surface, and if they can fix this, I'll be fine... I just want to be sure it's not a patch job just to...

I'm not 100% sure to be honest. I *think* screed, to mags around the perimeter at least, and then steel, then power trowel.

Reading about delamination, it's definitely that. The causes all add up. Vapour barrier, cold subgrade (started early after a cold night), thick slab (8-18" depth) sun exposure during the pour, windy day and air entrainment! I'm feeling sick, glad I haven't paid for it yet!

Sounds exactly like delamination in that article, thanks! I only tapped with my fingers to expose that hole...! So botched pour/bad surface finish... Will grinding and sealing be sufficient? Repour the whole thing?!? This is the only part of the entire job I'm paying for professionals!

Their GC ordered the concrete, though only 1 of 2 trucks left a receipt. They added a tiny bit of water, you can see the water bottle in his hand, a squirt here and there was all really...

Hi All! I hired a company to do my pour. I did an 8" slab, in floor heat, with an 18" thickened edge footing. 32 MPa, 5-8%. Pour took about 3 hours, and the crew finished the floor (smooth) for about 3 additional hours. They were good, hand screeded, hand trowel, then finished with a...

Thanks all, local insulation company had C-300 so I went with that. Less than half the price of a sheet at Home Depot... if I could even get it!

Hi all, Been loving the help I get here. Reading lots, and on the questions I've had so far, great help! I did search for this, and I've watched a lot of videos, but see different results so I wanted to ask. I have been backfilling a large hole with 7/8 GA to bring my grade up where I need...

Thanks Phil, I'll definitely be doing this, I need them to deliver some 6x6 WWM too, hoping I can get them to send 20' lengths! Thanks for the tip

So why the different callout by the engineer? I was told by him that the C200 is for high pressure applications, where the other 2" is cheaper and can be used outside the underneath of pad.

Hi, Not sure if this should go in "heating and A/C" or in "flooring" or "general"... Engineer spec are as follows. "2" DOW SM INSULATION, CELFORT 200 (OR APPROVED ALTERNATIVE) UNDER 5" SLAB PORTION OF THE FOUNDATION" "2" DOW SM INSULATION (OR APPROVED ALTERNATIVE) UNDER THICKENED EDGE...

Thanks All, 15 tri-axles later, I am at the bottom of the thickened edge slab (footing). I did rent a skidsteer, and its great. Only thing is, the loads seem to have gotten smaller since I rented that...
