Description : I have a burnt hole in a water barrel about 2 cm. How to make it so that the barrel does not run?
Last Answer : What "plastic" is it? PE, for example, can be welded (same material and hot air gun). General - the area around the hole can be roughened (on both sides) and sealed with eg epoxy (on both sides). The safest way is to make flanges, seal them (eg with silicone) and remove them on both sides.
