    • UV Protection: Apply a UV-resistant coating or reflective layer over the bitumen to protect it from sun damage.
    • Regular Maintenance: Conduct regular inspections and maintenance to identify and repair any damage caused by weather exposure.
  1. Poor Drainage
  • Issue: Inadequate drainage can cause water pooling, leading to increased pressure on the waterproofing layer and potential leaks.
  • Solution:
    • Proper Drainage Design: Ensure that the roof or basement has an effective drainage system to channel water away from the waterproofed surface.
    • Regular Cleaning: Keep gutters, downspouts, and drainage channels clear of debris to prevent blockages and water accumulation.
  1. Mechanical Damage
  • Issue: Physical damage during or after application can puncture or tear the bitumen layer, compromising its waterproofing capabilities.
  • Solution:
    • Protective Measures: Use protective coverings, such as gravel, tiles, or protective coatings, to shield the bitumen layer from mechanical damage.
    • Careful Handling: Handle tools and equipment carefully during application to avoid puncturing or tearing the bitumen.
  1. Compatibility Issues with Other Materials
  • Issue: Incompatibility between bitumen and other materials used in the construction can lead to adhesion problems and reduced effectiveness.
  • Solution:
    • Compatibility Check: Ensure that all materials used in conjunction with bitumen are compatible. This includes primers, adhesives, reinforcing fabrics, and protective coatings.
    • Testing: Conduct compatibility tests if using new or unfamiliar materials to ensure they work well with Bitumen 60/70.
  1. Inadequate Ventilation
  • Issue: Poor ventilation during application can lead to the accumulation of fumes and potential health hazards for workers.
  • Solution:
    • Ensure Ventilation: Provide adequate ventilation in the work area, especially in enclosed spaces like basements.
    • Use Respiratory Protection: Workers should wear appropriate respiratory protection to avoid inhaling fumes during application.
