Hydraulic Uplift Restraint

Promax Uplift Anchors ensure your Underground Tank will stay in the ground even when subject to high hydraulic pressure.

It is especially important these are used in areas that are compromised with a high water table or susceptible to flooding.

Fully engineered and reinforced, these modular anchors are simple and highly effective. We recommended they are installed on every tank to give you the assurance and peace of mind that your tank will be secure.

  • Modular – Just add concrete (Note: Concrete is not supplied)
  • Fully Engineered with PS1
  • Available for all tank sizes
