Structures below ground face ever increasing usage requirements. These usage requirements determine the quality level of the design. A combination of waterproof construction and a fresh concrete composite membrane offers safety to a very high standard. Sub-structure waterproofing systems are distinguished by their resistance to infiltration and plannable bridging of construction-related and unforeseeable cracks and separating cracks.

Implementation of waterproof concrete construction:

• Defining stress and usage
• Static dimensioning (component-specific)
• Waterproofing concept (planning of built-in components, penetrations, joint
• waterproofing, etc.)

For high usability requirements, the combination of an impermeable concrete
construction and a sub-structure waterproofing system provides extra benefits.
