Hello,

I have a 3,300-liter (870-gallon) rainwater tank made of PE plastic (manufactured in 1998) in my garden. Unfortunately, the garden in the front area settled by about 3cm (1 inch) while the downspout was removed for several months due to external work.

Because of the ground settling, the tank bent and cracked on both sides near the bottom.

Is it possible to repair the leak from the inside? Replacing the tank is unfortunately not an option.

Thank you very much

A 3300 l (870 gallons) tank is not something you can enter. I imagine repairs would be difficult. Maybe it would be better to expose the damaged area and seal it from the outside?

The tank has a height of 140 cm (55 inches). It is not comfortable, but walkable.
For external access, a portion of the terrace would have to be removed, which I would prefer to avoid.
