Description

Flexible, Crack-Bridging, and Bitumen-Free Waterproofing for Structural Protection

Remmers MB 2K is a high-performance, two-component, polymer-modified waterproofing compound designed for versatile applications in both new construction and refurbishment projects. Combining the strengths of flexible mineral seal slurries and bituminous thick coatings, MB 2K delivers long-lasting, crack-bridging protection that meets modern waterproofing standards—without the use of bitumen.

Key Features & Benefits

  • Multi-Functional Application: Waterproofs basements, foundations, floor slabs, plinths, balconies, and more.
