Repair concrete floor

[yartin]

Hi

Driveway is concrete, some parts has line cracks, I am thinking to fill them with mortar of sand cement SBR, what ratio, any other opinions?

I understand this solution won't last forever but don't mind repeating it as needed.

Thanks

You would have to open up cracks with a grinder to get anything into them. You could use a grey resin mortar.

I have opened cracks
Too many long cracks makes above product not cost affective
