Hot Bitumen – Heavy-Duty Waterproofing by Thermal Application
Hot bitumen is a waterproofing material used to protect concrete surfaces from water leakage. It is applied after being heated to its melting point, ensuring deep penetration and excellent adhesion to the surface.
It is considered one of the most effective waterproofing systems in construction and road projects.
📐 Technical Specifications
- Type: Oxidized or heat-modified bitumen
- State: Solid before heating – liquid after melting
- Melting point: 160–180 °C
- Color after application: Glossy black
- Adhesion: Very high on concrete and metals
- Permeability: Almost zero – strong barrier against water
- Flexibility: Low – requires additional protection against cracks
🛠️ Common Uses
- Waterproofing exposed concrete surfaces
- Protecting foundations and buried walls
- Waterproofing floors before tiling
- Base layer before installing bituminous rolls
- Road and bridge projects
- Waterproofing underground tanks and inspection chambers
✅ Advantages of Hot Bitumen
- Excellent resistance to water and moisture
- Withstands harsh weather conditions
- Provides a thick, durable protective layer
- Strong adhesion to the surface after heating
- Suitable for large-scale projects requiring high quality
⚠️ Important Notes
- Requires heating with special heaters
- Must be applied by professional technicians to avoid burns or errors
- Recommended to use a protective layer above it, such as rolls or tiles
- Not to be applied directly on heat-sensitive surfaces
