Is the tree looking for moisture?

    This is amazing!!! The tree roots are following the grout lines! Anyone know why? Wondering if they're trying to find moisture?

    It is most likely trying the breathe...get oxygen to live. With all the bricks around the base, the tree roots can not get enough oxygen so it sends them to the surface and they spread.

    @Ronni I've seen this happen in parks and through tarmac but not the picture you've added and apparently it's called Root Heave.

    Root heave, sometimes called pavement heave, is triggered by tree roots that do not have sufficient growing space underground, caused largely by compacted soil that has been densified to provide structural stability for the overlying pavement. This forces the tree’s roots to colonize immediately underneath the hardscape surface, causing the paved surface to lift, crack, and create aesthetic and safety issues.

    Root heave is a challenge for municipalities because, in addition to its unsightly appearance, it poses a major liability risk due to the tripping hazard it causes.
