Thanks for joining in the discussion on Workshop @aarons. Welcome aboard. We hope you get loads of useful advice, information and inspiration for your projects from our ever-helpful community members.

Could you please clarify if you use the tank to supply drinking water? Not sure if it matters to the proposed solutions from members but it might be relevant....

Hi aarons,
Sikaflex has a range of products which can seal the crack from the inside and out which are suitable for drinking water applications also.

Betta make a product called Water Plug, this is suitable for drinking water tanks. It is put on from the outside of the tank. I have used this product myself and had success every time.

Hi @Tanyamaree71,

We'd be pleased to assist you with your leaking tank. Preparation of the crack and surrounding area are essential in getting a superior bond for the product to adhere correctly. What sort of preparation did you do to the surface before applying the products?
