Sub-structure waterproofing system Zemseal®

Construction seal with high quality usage of basements

Additional waterproofing measures are usually required to meet all the structural and physical requirements that arise in waterproof structures. In the case of high usage requirements, the use of a safe, fresh concrete composite system has proven its worth. Our Zemseal® sub-structure waterproofing system encloses the water-impacted building components and forms a secure and integral external waterproof protection. MAX FRANK Zemseal® sub-structure waterproofing technology combines mechanical and adhesive bonding - "dual-bond" technology.


  • Dual-Bond Technology: mechanical and adhesive bond
  • Tested leakage protection
  • Excellent crack bridging
  • High material efficiency (only 50 mm joint overlap)
  • Suitable for high-pressure cleaning
  • Simple handling due to low roll weight
  • Effective diffusion barrier - protection against radon gas 
  • European Technical Assessment (ETA)
  • German National Approval
