Which came first: the crack in the concrete or the plant? Many landowners with plants sprouting through sidewalks and driveways are curious about whether the plant took advantage of an existing crack or physically caused the fissure in the slab. The answer falls somewhere in the middle. The more you know about the cause of this costly concrete problem, the sooner you can find a resolution.
Small Plants = Big Concrete Problems
Your concrete contains microscopic cracks invisible to the naked eye. Plants have new cell growth at the tips of their roots. As the plant grows, so does the root system. The sensitive tips of the roots have the power to seek the path of least resistance for growth. Microscopic concrete cracks present this path for plants growing beneath your sidewalk.
Once a plant’s roots discover a microscopic crack in the concrete, they force their way into the slab. Even small weeds and seedlings have the power to displace concrete using potential energy from root growth. Over time, the plant’s continued growth can crack, break, or buckle the surrounding concrete – at which point you may see the plant break through the surface.
Tree Roots and 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. You may have to cut the roots or even remove the tree to permanently resolve this problem.
