Hole in the concrete slab
 
Hello all. We just relocated our laundry room and are left with an area about 4'X3' by 2" deep where the washer and dryer sat. There is a french drain in the bottom of the "trench". This space will be a walk-in pantry with wire shelving sitting on top of whatever we decide to fill the hole with. We are not wild about the idea of carrying or wheel-barrowing that much concrete across the good floors. For the short term, we were considering filling the void with 1'X1' concrete pavers, since the size is fairly predictable, and maybe putting a little morter in the spaces. Anyone else have any ideas?

You may consider mixing the concrete in the hole. Get it as close to the surface as possible and finish with a good portland patch.

Hey, that's something we hadn't considered. We could tape off the surrounding floor, which also happens to be concrete.

We should just be able to mix the stuff with a hoe and level with a 2X4, I would think.

Should we try to do a little bit at a time so we don't over fill?

They make a bag now that you mix the bag of cement in, and then carry. Otherwise, mix in a wheelbarrel, and put in 5 gal buckets to carry to the room.

I would mix and add as necessary to reach the top surface. Don't allow to dry in layers or it won't bond to each other.

Okay, we filled in the cavity last night. We used 3 bags of 'sackcrete' and the result is pretty good. There are a couple of rough spots in the back corner where we really couldn't reach but all in all, considering neither of us has done any work with concrete, it's pretty good.

Flooring Dude mentioned a "portland patch". Could someone elaborate on that please? Where to obtain it, how to use it, etc?

As always thanks to all who respond.
