How to repair cracked concrete driveway?

[davedave]

Hi, I have some long cracks in my driveway - are these suitable to fix myself and if so what products? Or would I be better paying someone to do the job?

Hi @davedave 

Well  You  could simply use cement powder and water into a slurry  (extra  sand wont fit the fine cracks)

I t will fill the cracks as is but is is possible to recrack at a later dated.

Another way is

Hello @davedave 

Welcome to the Bunnings Workshop community. It's wonderful to have you join us, and thanks for sharing your question about filling the cracks on your driveway.

It's great that you've received good advice from @Jewelleryrescue. Just to add to the suggestions made, I recommend using Gripset Betta 1L Concrete Crack Filler. Since the cracks are not very big this filler should sit in nicely between the cracks of the concrete. Please make sure to clean in between the concrete cracks before applying the filler. 

Please make sure to wear personal protection such as gloves and goggles when working on your project.

If you have any other questions we can help with, please let us know.
