Convaults need to be regularly sealed. Over time the concrete expands and contracts causing small cracks and allowing water to find its way into the secondary containment giving a false leak alarm. You can not shop vac this water out. The entire secondary must be placed under vacuum and resealed.

Preventative Maintenance Plan: check your leak tube regularly and inspect the top for small cracks forming. If water has intruded call us and we can help.

Convaults need to be regularly sealed under vacuum and achieve operability standard with documentation ready for inspection. Like a car needs an oil change periodically, a Convault tank needs to be sealed and tested.

Preventative Maintenance Plan: Plan to reseal the top under vacuum every 2-3 years. Depending on your region’s inspections, test for operability annually or every other year. Call us and we can help.

Convaults need identification placards, breach of integrity tests and resealed to be ready for inspection. Reconditioning the tanks by sealing, treating the tank nipples for rust, repainting and replacing the product identification every 3-5 years is critical to optimize the life of a Convault tank.

Preventative Maintenance Plan: If you reseal the top every 2 years then you only need to recondition the entire tank every 5 years. Or you can plan to recondition the entire tank every 3-4 years.

Call us for hassle free help.

Through expansion and contraction water can invade the space between the vault and exterior texture of Convault tanks. These concrete tanks can show separation from the vault and exterior stow.

Preventative Maintenance Plan: When you observe separation beginning, repair and seal asap before it spreads.

If the tops are not sealed water can get between the concrete vault and secondary. This results in water leaching calcium from the concrete as it escapes. The integrity is not compromised but it is a symptom that the top needs to be sealed under vacuum asap.

Preventative Maintenance Plan: Seal the top every 2-3 years with the secondary under vacuum. Calls us and we can help.

Water corrodes the metal nipples over time. The worst cases require rust converter, epoxy and rust inhibitive paint. In addition the transition from concrete to metal requires sealant so water intrusion into the secondary is avoided.

Preventative Maintenance Plan: Remove rust, and use converters and inhibitive paint every 3 years. Let us help.
