Resurfacing or Concrete Pavers

The previous owner did a **** concrete job and there are large crack everywhere in both front driveway and rear concrete slab. The total area is about170sqm.

I got plain concrete resurfacing quote for rear area which was about $3500 including grinding, epoxy filing and 3mm thick resurfacing. They said they can't provide warranty that it would not develop cracks because of previous severeds and soil movement.

Would concrete pavers be better option instead? Can they be installed over existing concrete?

I am looking for long term cost effective solution.

 

Existing concrete slab is the ideal base for pavers as this is more stable than compacted soil, it will not settle where there are wheel tracks.

As it raises the surface level, ensure that water does not flow back into the house or cover up brick vents or weep holes.

 

Which thickness you will recommend?

Will 300mm paver suffice?

 

Check with the manufacturer as the 50mm paver is recommended for traffic.

 

Typically a existing driveway isnt flat but may be curved. To avoid pavers etc cracking and adjust for heights and joints they are laid on a thin sand bed as well. Raising surrounding lawns etc by 60-70mm should pose no major issues. The edges will have a mortar supporting bed anyway. But check drains etc and driveway splay and garage entry where that height may already be level with the road / building making the existing surface unsuitable. The two ends may need to be cut with a conc saw, ripped up and dug deeper. Adding to cost v's a roughy base (with reo) pour and then a new bed that is uniform end to end. Speak to a paver.
