Can tree roots go through concrete?
Tree roots present an even bigger potential problem for concrete surfaces. They move through cement in the same way as smaller plants, but with much greater potential energy. Trees near your concrete areas could push roots beneath and through the surface, causing expensive damage and dangerous cracks in the slab.

Some effective methods are:
- Putting down a layer of pea gravel under the new concrete allowing the roots to expand.
