    Default Pebblecrete small slab

    I need to add about 30mm height to a 2.40sqm 80mm thick square slab of pebblecrete that was boxed and poured on top of a carport concrete floor in the 80s to mount a pool pump shed on only the shed is coming apart n needs replacing. 30mm Limestone pavers have been layed over the original pool surround right up to the doorway of this shed which is why I need to raise the shed slab 30mm
    Can I box the pebblecrete slab and get away with pouring a few bags of lanko leveller on top with a bonding agent or slurry or just concrete will do? I need to install a slab fixing kit to this new garden shed iv brought

    ....not sure however I doubt the concrete at only 30mm thick would likely crack.

    Maybe others can comment, on if a mortar mix would achieve a better result?
    As an option, could you lay some pavers on a mortar base and mortar joints. Sit the shed on these and fix into the pavers and concrete slab.


    Assume the slab fixing kit is a bracket and screw/dynabolt simular to this? https://abscosheds.com.au/accessories/anchor-kits/
