Hi ya Mr Jay :mrgreen:
The ‘wiser’ inside injectors/Cos wont attempt wide cracks, believe it or not. they actually realize their injection wont hold up long enough to get THEM through their warranty period or they realize there is lateral soil pressure,roots etc that causes many cracks and can cause further widening which then screws up their injection.There will always be a few who`ll do anything for money
Hope your doing well Jay man.
