Product Information

AQS-1 is a stable colloidal silicate solution that is used in the AquaSeal water shut off system. When added to water it will have a high pH, allowing the blend to be stable indefinitely, but when the pH is lowered the solution will slowly solidify to shut off a given area.


  • Colloidal silicates are more stable than silicate solutions
  • Set up times can be controlled to optimize for specific applications
