Bolted Tanks Don't Leak
It’s normal for customers to have questions about leakage when storing a liquid, especially when the system storing the liquid is made up of thousands of holes!
When constructing a bolted tank, the joints are sealed either with gaskets or sealants. As long as this is done right, and the correct gasket or sealant is chosen for the application, leaking will not occur. Hydrostatic testing upon erection also ensures a leak proof system prior to commissioning.
The more holes, the higher likelihood of leaks

It can be in other storage applications, but not for bolted tanks.
If a leak in a bolted tank does develop over time it can usually be solved just as it would if it was discovered during hydrostatic test, by adding some additional sealant and/or tightening the bolts, making the repair safer, simpler and more cost effective than a welded tank repair.
As a comparison, when welded tanks leak the repair involves expensive welding, testing, and re-coating.
Repairing a leak is expensive & complicated
Adding a welded floor will make the tank "safer"
Replacing the bolted floor with a welded floor would not result in a “safer” bolted tank.
Both floor types (bolted and welded) are tested to the same industry accepted standards (API or AWWA) and both can be equipped with the same leak detection system when necessary.
Welded tanks are more structurally sound
Bolted tanks are as structurally sound as any other storage tank type. Bolted tanks are designed to well-accepted and accredited AWWA D103 standards and are widely used for various liquid applications.
Fabrication of bolted tanks take place in an automated factory where parts are manufactured and prepared using CNC machines, which results in a very precise and robust final product.
One of the unique benefits of a bolted tank is that the steel receives its final coating at the factory.
This means that both sides of the floor sheets are coated to the same high standard, making bolted tanks highly corrosion and leak resistant.
This feature eliminates the need for additional corrosion allowance and cathodic protection, which is generally required on a welded floor where the underside is un-coated.
