Tree Roots Lifting Pavers: Switch to Gravel or Raise Patio

Question: 15-yr-old London plane (or maple) roots lifting pavers installed 3 yrs ago (gravel base, sand, pavers). What now?

Answer: Gravel Surface Flexes with Roots; Raising Patio Delays Problem

London plane has surface roots strong enough to lift pavers. Cutting roots risks tree death/canopy loss. Re-paving repeats the issue.

Best: Replace pavers with gravel—walkable, flexible under root pressure.

Alternative: Raise patio height to clear roots, but they'll likely surface eventually.
