Underground Structures

To provide a dry environment, any structure built below ground level will require waterproofing. Choosing the most appropriate waterproofing system will depend on a number of factors including:

  • Depth below ground level
  • Construction type / material
  • Soil type
  • Proposed end use
  • Soil contaminants / ground gasses
