Sludge tank

The primary purpose of sludge silos is the storage of your sludge. Covering your stocks guarantee the quality of the sludge by eliminating rain water entry and limiting odors.

Our silo covers adapt to fit all your structures (with : bridge, half-bridge, central pole, central beam or platform) in tight or sliding versions. Our custom crafted soft covers take into account any constraints you have.

Our covers are mounted by a cable-attached to a central structure (existing or planned) and a concrete wall. We are confident we can integrate with your existing environment. The evacuation of rainwater occurs outwards.


Our sliding covers are designed specifically for your structures. They protect your tanks from odors and any freezing.

The main advantages are:

  • Aesthetically pleasing and lightweight
  • Easy and efficient to use, safely
  • Fabrics specially designed for H2S, NH3, hydrocarbons and solvents
  • Structure designed to resist to gaseous atmospheres, snow and tropical storms
  • High durability solution
