For you experienced paver installers- I have been installing paver walkways and patios for about 5 years now. I want to take on some paver driveways this year, but i am a little intimidated at the thought of vehicle traffic on the pavers. You know sagging spots where the cars park and such. What are some tips you guys can give me so I have the confidence to complete a job like this? Thanks in advance for any advice.
