Plants growth noted on external wall.
Existence of plants or vegetation, such as fast growing trees in external wall or other parts of the building or structure can cause cracks in walls due to expansive action of roots growing. The plants begin to grow in opening or fissures of walls, and If these are not removed well in time, it develops wall cracks in houses. This can cause damage to the structure and moisture intrusion which lead to dampness/ seepage related problems.
1. removal of the plants along with roots;
2. renovation of the external wall damaged due to roots.
