mix for leveling garage base?!?!

[shaiboy_uk]

Hi all,

I wonder if anyone can help, or direct me to the right direction.

I am in the final stages of building a base for a garage, now just need to put a top screed on top of the concrete that was poured in for the base. the base needs leveled from a range of 5mm to about 15mm at points due to uneven concrete.

Can anyone recommend a mix to use to level it that will be strong enough for a car to go on top of? someone said to me previously a cement, sand and ballast mix, but I don't know at what ratios and if is still the best mix? I don't really want to spend to much but want to do it right of course.

Can any help? Apologies if I've posted in the wrong place, just couldn't see anywhere else.

Thanks in advance.

Cheers

I wouldn't use a cement:sand mix. At that thickness it won't last 5 minutes on a garage floor.

You need something that can be floated on as self smoothing liquid that will achieve high strength. Rockbond floor levelling compound would do the job.
