Hi there,
Yesterday we laid a concrete floor for a workshop im building. The size of the slap is 20x20 foot and 5.5 inches deep. Im not an expert but have done some building in the past so im not a total novice.
We have laid some other smaller slabs and there has been no problems,
after we tamped the slap I floated it with a bull float and obtained a really smooth finish.
When I had a look at it this morning its quite noticable that there is hump in the middle of the slap, its not noticable at first glance but when you put a straight edge across it you can see the problem. Since this is going to be a workshop floor where I want to do welding etc. this floor will just not be acceptable.
I dont know what went wrong it looked fine last night, all I can say is that the driver made the mix very wet maybe that had an effect on the slab as it cured.
You can only imagine my dissapointment!
What is the best solution to this problem, cut off a layer and relay?
Someone mentioned concrete planers to me, that mill the concrete down, I presume this would leave a rough finish?
Any suggestions would be great. Thanks.
