Hi @corky55
I think your drive way is quite fixable it is strange the morter came out like that .
I suspect more mortar will come out other areas so Bunnings sells cute low cost pressure washers. EG
Gerni 3000 1670PSI 1400W High Pressure Washer I/N: 0254294 $139

Bunnings will also hire them out but money is better spent towards your own washer then you have that tool for many jobs.
So high pressure wash you drive (Not tooo close as high pressure water can cut bricks in half) So find the just right height to clean but not super blast. That washer as mention above comes with a patio washer attachment for bricks and cement as a bonus. that should apply the right pressure.
WHY clean your drive first? I am aiming at helping you discover more weak morter points to fix them all at the same time plus you will have fresh look drive,
Ok Lets say some more morter came out thats good as it is the weak stuff.
Now one bag of should be enough
Australian Builders 20kg Sand And Cement Mix Bag I/N: 0760612 $9.44

Starting at one end of the drive to the far end.
Mix up a quarter of the bag in a wheel barrow. big bucket. or a regular bucket wearing gloves use a small garden spade as a big help to mix all the cement with water scraping into the corners. Add water gradually until it is like tooth paste consistancy .
Lightly spray your drive way with water not so the water is running this helps new cement bond.
Use you small mixing garden trowel to spoon the cement into the individual holes and damaged morter lines carefully as to not make a mess with a dust pan brush smooth it level. Your done.
waste not want not.
Walk around your property fill any other places and path cracks with the left over cement in the bucket. or empty remaining cement on the dirt or grass and let it set in lift able cement rocks and dispose of in bin.
Its inevitable the drive will have some cement mess out of the intended spots so leave the mortar set for 30 mins.
Now use the dust pan brush dipped frequently in water bucket and brush of any excess cement on brick faces (Try no to dig into your repairs) the water helps dilute cement surface mess (the morter in cracks wont be effected unless overly brushed)
So now the thick cement on brick faces is wiped 98% clean Use your hose on wide shower spray (not pressure washer) lightly hose your dirty brick faces clean with out hosing out repairs, Hose the grey water of to one side or drive. Some grey will leach out of your morter repairs do not worry we can clean that on a final clean after a week. You can use driveway with cars etc same day as morter is flush or below brick level.
One week later your garden hose can be aimed at brick faces only to finish cleaning them on jet.
Dont forget to clean those other patchs you did around the house.
It is very easy to wash out new unset morter so wash unset morter very sparingly
You should have a clean patch driveway
