I recently made a 3000 square foot concrete pour on a hot day without sufficient personnel. As a result, I have a strong floor but not a level one. Some places are 2 inches low. The floor was a deep pour, 6″, so the low places do not create a structural problem, but do create a major finishing problem.
A local concrete supplier suggested I fill the low places with a sand mix then top it with “Quick Crete Resurfacer” I believe the resurfacer is a strong epoxy, self leveling compound that I can feather at the edges.
Does anyone have any other suggestion to fix this pour?

Hi Russell,
Hate to admit it, but everyone in this business has been there done that.
You gave the size of the pour but not the size of the damage, the expected use for the slab or the products (carpet,tile etc) you intend to cover with, if any?
If you have a lot of 2" holes and need a lot of fixing your talking a lot of work but you have time. (now)
The sand mix idea I would drop.
You're going to have to have to use a bonding agent and the product will have to have a strength equal to or a little stronger than your original mix.
I don't know where you're located, but first chance you have call your construction specialty supplier and start getting quotes on the filler material that your going to need.
A call to your local Mapei representative or a visit to their web site will go a long way to find a compatible product to level out your holes and still feather.
Keep us all informed.

*Hey you guys - I worked for a guy many years ago who professed to be a flat work expert. He was always talkin' about a product called "Rakolith", or something. He said that any remodeler would at some point need it to level a bad pour. I have always avoided flatwork like vegetables so I never have had need of it, but it sounds like what Russel needs. Anybody ever hear of that one?
*Russell: I'm with Gabe. Drop the sand mix idea. If the floor is to be covered you might consider a self-leveling topping like ARDEX or an equal product. These are products you mix with water and are self-leveling, cementitious, & non-shrinking. If the floor is going to be left uncovered contact a dealer for Dayton-Superior products. They have some excellent products to repair problems like yours. 800-745-3700 is their headquarters if you need to find a dealer. I am not familiar with "Mapei" in Gabe's post but it is probably a similar source. We have used both types of the products I mentioned in various re-model jobs. The product you need is out there you just need to go find it. Hope this helps Ron
