Polyurea Coating – Secondary Containment

Project summary:

  • Bund wall leaking excessively (8mm / hour) when under hydro test
  • To achieve compliance with Worksafe a maximum leakage limit of 1mm / hour must be attained 
  • Surface area consisted of 1,000 m2
  • Coating installation consisted of two primer coats followed by 3mm of polyurea 
  • Subsequent hydro test result 0.3mm / hour (minor leakage due to manholes)
