How important is waterproofing after repairing a crack? (2024 Guide)

The Critical Importance of Waterproofing After Crack Repair in Masonry

In the field of masonry, waterproofing after crack repair is a crucial element for ensuring the longevity and safety of structures. At Maçonnerie Montréal, we understand this importance and are committed to providing high-quality services in Montreal, Laval, Longueuil, and on the South Shore and North Shore.

Why is Waterproofing Critical?

Prevention of Water Infiltration

  • Barrier Against Moisture: A non-waterproof cracked wall can allow water to seep in, leading to significant structural damage.
  • Protection Against Weather: In Montreal, the varied weather conditions require robust protection against rain, snow, and freezing.

Preservation of the Structure

  • Preventing Deterioration: Infiltrated water can cause iron elements to rust and the degradation of joints, compromising the building's stability.
  • Longevity of the Building: Proper waterproofing extends the life of the structure by preserving the integrity of the materials.

Comfort and Health

  • Mold Prevention: Excessive humidity promotes mold growth, which is harmful to the health of the occupants.
  • Thermal Insulation: Adequate waterproofing contributes to better thermal insulation, thereby reducing heating costs.
