SprayShield Green Reaches New Depths of Ability:

Edmonton, Alberta


The City of Edmonton need to restore and provide semi-structural corrosion protection for two wastewater maintenance holes, each over 100’ in depth.


Sprayroq® SprayShield Green was chosen to protect wastewater assets from hydrostatic pressure and H2S corrosion.

Key Challenges

1) The depth of the structures reached over 100’ below the surface.

2) The work was to be completed when ambient temperatures were steadily sitting around -5°.

3) Preparation for the project was extensive.
