There is a lot of misinformation around weeds and patios.
When a patio is constructed properly, weeds are not going to grow up from underneath and through the patio. There is typically a 4 – 6″ base of crushed stone and screening that is used and it is tamped down to make a solid base. A best practice would be to use a polymeric sand to spread in between the pavers and allow it to harden.
If the correct protocol is followed, weeds will not grow from underneath the patio. What can and will happen is weeds growing from seedlings that get blown onto the top of the patio either by wind, trees, or mowing. This is far different and much easier to maintain than weeds that are rooted below.
It is a common misconception and knock against pavers that weeds grow from below. When built properly, this is not the case! To find out more about patios and outdoor living spaces, go to archadeckofcharlotte.com
