Penetron® Feature: Penetron White Tank system


A white tank is a concrete structure that is waterproofed entirely from inside the concrete, thereby offering substantial benefits to both builder and owner. The system represents a huge improvement on the traditional black tanking practice, which relied on environmentally unfriendly bituminous membranes and/or tar products, that used to be fixed to the concrete surface. Whereas other white tank systems rely on high-grade concrete formulations and tedious installation of components, the Penetron White Tank stands out in its simplicity, self-healing capacity and the fact that it allows ordinary concrete to be used.

Main Benefits

  • Substantial time and cost savings as waterproofing is included in concrete placement process
  • Waterproofing abilities remain active if surface is damaged
  • Self-healing ability for the life of the structure
  • Approved for potable water use
  • Easy access for repairs if necessary
  • No need for high-grade ultra dense concrete to achieve waterproofing


  • Penetron Admix completely waterproofs the concrete body with the world-renowned Penetron crystalline capillary technology (click here to view a 3 minute video).
  • Penebar is installed at the concrete joints and swells up when it comes in contact with water, thereby preventing any leakage through joints and penetrations.
  • Penecrete Mortar is used to fix form-tie holes as well as honeycombs, penetrations, cracks or bugholes.
