Bitumastic 50 is an ultra-high build, single-component coal tar mastic manufactured by Carboline. It’s designed for heavy-duty corrosion protection of steel and concrete substrates in aggressive environments and for below-grade damp proofing, providing excellent resistance to moisture, soil, and chemical exposure.

This coating is black in color and has a solids content of 68% ± 2% by volume and can be applied in one or two coats with a dry film thickness of 18 mils (457 microns), up to 30 mils (750 microns) in a single coat. It’s self-priming with single-coat capabilities and complies with standards such as MIL-C-18480-B and Bureau of Reclamation CA50.

Bitumastic 50 PDS Sheet >

Bitumastic 50 is used in harsh industrial, civil, and buried applications where steel or concrete requires robust protection from corrosion, abrasion, and immersion up to 120°F (49°C). Common applications include:
  • Below-Grade Structures: Damp proofing for foundations, retaining walls, basements, and buried concrete/steel elements exposed to soil moisture and aggressive groundwater.
  • Pipelines and Tanks: Interior and exterior linings for underground pipelines, storage tanks, and vaults in petroleum, chemical, or wastewater systems.
  • Wastewater Treatment Plants: Coating for concrete manholes, sumps, channels, and steel supports in areas subject to sewage, effluents, and corrosive fumes.
  • Civil Engineering Projects: Protection for dams, bridges, and reclamation structures per Bureau of Reclamation specs, including submerged steel piles and concrete surfaces.
  • Industrial Facilities: Maintenance coating for machinery bases, equipment supports, and floors in refineries, chemical plants, or manufacturing sites with soil or chemical contact.
  • Military and Marine Installations: Corrosion barrier for buried or semi-buried steel components in non-potable immersion service, compliant with MIL-C-18480-B.
