You can use a wall connector ( channel ). google "wall connector".
But, if you intend a slab floor to the new garage, then why not float your slab, and then build your wall off the slab?
By the way, dont mix the concrete so soupy, esp for footings - wet concrete is weak concrete. A semi-dry mix is best for pressure areas.

hi thanks for the advice will get them wall connecting plates from screwfix. As for the footings i had that ready mixed put plenty of rebar in too so i think it will be pretty solid gone down roughly 750mm deep. I dont fancy putting the garage base ontop then build wall because my ground is clay so dont trust it or do you suggest it will be ok ontop of the footings? Will also be putting rebar in concrete base just to be on the safe side

all your help is greatly appreciated

thanks

You dont need re-bar in residential footings or "base" ( slab? ). be careful with your terms, base has specific construction meanings.

What exactly are you doing here? Are you intending a concrete slab garage floor? If so, do you intend to dig out and hardcore, membrane, insulation and slab? How high are your walls going?

 

[iamlee2002]

Hi yes plan to do 100mm hardcore, 50mm sand then dpm then 150mm of concrete for base. Walls will be just under 3 meters does that sound ok? Must be careful whilst preparing the base as water main is very near. Thx in advance for the advice

OK. Is that footing finish your finished floor level?

 

[iamlee2002]

Hi nope floor level is goin to be 3 inch above footings

Then float you slab to that FFL height and build your wall off the slab surface.
