Mastic and Sealant
Bernet Mastic & Sealant grades M1–M4 with QC-verified properties: penetration at 25 °C, softening point ≥70 °C, specific gravity 1.0–1.2, 160–165 °C mixture temperature. Tested per ASTM D5/D36/D70.
Quality-Controlled Sealant Grades for Lasting Performance
Mastic & Sealant Bitumen
Bernet Bitumen manufactures bituminous mastic & sealant compounds engineered for long-term waterproofing, joint sealing, and crack repair in roads, bridges, tunnels, and building envelopes. Each grade below reflects the exact QC controls recorded in your MASTIC sheet.
Engineered for Sealing and Waterproofing Performance
Every batch is verified for softening point, penetration (25 °C), specific gravity (25 °C), mixture/application temperature, and related QC checks. This ensures consistent workability during installation and reliable in-service behavior under thermal movement and loading.
Engineered for Strength
Comprehensive Range of Mastic & Sealant Bitumen
Below are our Mastic & Sealant Bitumen grades. Each section provides a short technical overview, indicative property ranges, typical applications, and standards. Where projects require tighter tolerances, we provide custom production and technical support.
Bitumen M1
