Our driveway is now 2 years old and deveolping several cracks most of the prep work was done by myself. 62 sq mtr area was dug out and had to add 8 cubic mtrs of crushed rock as bobcat guy took to much out used wacker plate on this for 1 whole day while watering as well .Coloured concrete 25 mpa 9.6 cubic metres approx 130 -150 mm thick using sl 62 mesh with saw cuts at every 1.5 sq metres 30mm deep are the cracks now forming due to the crushed rock compacting over time? I know theirs not much i can do about it would just like to know WHY?
Driveway has also been sealed , whats is the best way to fill cracks if any to retain original look and then perhaps re seal these areas.
Thanks
