Pad recommendations.
Pad recommendations.
(OP)
I have a small pad 6ft by 2ft of solid, as in stable, brick work rising from a concrete pad, about 3ft tall. The top surface is not level with various high and low areas measured in about an inch.
There are surrounding wood sill-plates surrounding the area of discussion.
I would like to level the 6ftx2ft area with concrete. It can only be about 1 to 1-1/2" thick. It will ultimately be required to support 3,000 pounds sitting on a stand with four legs.
Will this be too thin a layer of concrete?
Any suggestions or recommendations?
Alternative solutions?

RE: Pad recommendations.
Usually 4" would be a better thickness, depending on the loacation of the support legs relative to the outside dimensions.

Here's a picture to help the discussion.
The hammer is for scale.

Notice the back trench and the right rear corner. About half an inch uneven. The four legs will have to be in the four corners and will be subject to these deformities.
If I go for 4 inches I will be up the drywall - a poor situation.
Maybe a polyester filled concrete?
Epoxy? Ouch $$$

RE: Pad recommendations.
For your one and a half tonne weight (am I correct? not sure about pounds) assuming you have decent size baseplates I would just put some chicken mesh down and then use a 3:1 sand/cement screed.
RE: Pad recommendations.
Yes one and one half tons.
The feet will have plates to spread the weight a little but we're still talking 200lbs/in2

RE: Pad recommendations.
Am I correct I get about 1.4N/mm2? You should easily achieve 15N/mm2 with your screed.

That's excellent news. Thanks!

There are lots of them around.
Basically they are a very runny grout that self levels under gravity. You will need to provide a timber box around it to stop it flowing out.
Any of these above grouts should be fine for loads up to about a ton, above that, check with the manufacturer.
