Hi, I am re-paving my driveway (1050 square feet) and want to prevent weeds and grass from growing under it. My neighbours did theirs 2 years ago and either the grass or weeds pushed their driveway up and and it cracked causing the grass and weeds to grow throughout. Having your driveway paved isn’t inexpensive and should last between 7 and 10 years if well maintained. Any suggestions

I would think that a reputable contractor should be able to install a driveway without it heaving and cracking and weeds growing through. I my eyes your neighbour has a warranty claim. That however isn’t your question so on to your question. You could use an underlay called geotech. This is a think fabric and should aid in reducing any movement and will block weeds from pushing through. Good luck with the project.
