The Process of Insulating and Waterproofing a Brick Wall or Masonry in Montreal

Step 1: Assessment and Planning

Before insulating and waterproofing a brick wall or masonry, a professional will conduct an assessment of the building to identify problem areas and choose the appropriate materials and methods. This includes considering Montreal's climate and the specific needs of the structure.

Step 2: Selecting Materials

Insulation materials like mineral wool, rigid foam boards, and spray foam are commonly used for brick walls and masonry. For waterproofing, silane/siloxane sealers, elastomeric coatings, and cementitious coatings are popular choices. The selection will depend on the specific requirements and the building's characteristics.

Step 3: Surface Preparation

Proper surface preparation is critical for a successful insulation and waterproofing project. This includes:

  • Inspecting the surface: Identifying cracks, loose bricks, and other damage that need repair before insulation and waterproofing.
  • Cleaning the surface: Removing dirt, debris, and any loose materials to ensure proper adhesion of insulation and waterproofing materials.

Step 4: Insulation Installation

Once the surface is prepared, the insulation material is installed. This can involve:

  • Applying mineral wool: Mineral wool is placed between the wall cavity, providing excellent thermal insulation.
  • Installing rigid foam boards: Rigid foam boards are attached to the exterior or interior of the brick wall or masonry, offering great insulation and moisture resistance.
  • Applying spray foam: Spray foam is applied onto the surface, expanding to fill gaps and providing exceptional insulation and moisture protection.

Step 5: Waterproofing Application

After insulation is installed, waterproofing materials are applied to protect the brick wall or masonry from moisture infiltration. This can involve:

  • Applying silane/siloxane sealers: Silane/siloxane sealers are applied to the surface, penetrating the brick or masonry to provide long-lasting water resistance.
  • Applying elastomeric coatings: Elastomeric coatings are applied to the surface, forming a waterproof barrier that can expand and contract with temperature changes.
  • Applying cementitious coatings: Cementitious coatings are applied to the surface, creating a durable, waterproof layer that protects against moisture ingress.

Step 6: Inspection and Maintenance

After insulation and waterproofing are complete, a professional will inspect the work to ensure proper installation and performance. Regular maintenance, including periodic inspections and cleaning, is necessary to maintain the integrity of the insulation and waterproofing system.
