Wondering if your concrete trenches or sumps are holding fluid as per the AER regulations?

Here’s an example of a common issue many of our clients experience with these floor drains.


Containing fluid in concrete floor trenches and sumps and remaining compliant with AER D-55.


  • Concrete is porous and is not a barrier to liquid and therefor needs to be protected with specialty coatings that can resist the chemicals and heat from operations.
  • Sometimes this concrete is old, cracked, damaged and leaking water into the trench space from underground water sources.
  • This will prevent any type of coating from successfully being applied to the surface.


  • Fix the concrete with a cementitious based waterproofing material called Penetron that self-heals and blocks water from entering into the trenches and sumps via small cracks and voids in the concrete.
  • This Penetron material forms insoluble microscopic crystals in the presence of moisture and plugs off all open areas in the concrete even against a high hydrostatic pressure build up.
  • Once the concrete is fixed and water tight – specialty coatings can then be applied to the surface of the concrete to protect and preserve the substrates from chemical exposure.


  • To provide compliance with AER D-55 regulations, Halo offers several options for double wall containment in your sumps and trenches. Ask us how by clicking the link below:
