The Influence of Trees and Plants on the Formation of Cracks in Brick Walls

At Maçonnerie Montréal, we frequently encounter an issue that is seldom discussed but crucial: the impact of trees and plantations on the integrity of brick walls. This article aims to detail how the surrounding nature can, unsuspectingly, damage masonry structures.

Roots: An Underground Threat

Expansion and Pressure

  • Root growth: Trees near a structure can extend their roots under the foundations, creating pressures that lead to the formation of cracks.
  • Water and soil: The roots absorb moisture from the soil, causing changes in volume that destabilize foundations and walls.

Foliage and Moisture

Consequences of Dense Foliage

  • Moisture retention: Dense foliage near walls can retain moisture, increasing the risks of water infiltration and cracking.
  • Climatic variations: Temperature variations caused by the shade of trees can also contribute to the degradation of mortar joints.

Management and Prevention

Protection Strategies

  • Pruning and trimming: Proper management of trees, including pruning and trimming, can reduce the risks of structural damage.
  • Plant selection: Opting for slow-growing species with shallow roots to minimize the impact on structures.
