Repair Cracked IBC With SUGRU

The IBC container used to hold rainwater on our allotment had developed a large and nasty crack near the bottom. Repair posed a challenge; any fix would need to be waterproof, and extremely strong given the pressure that will be exerted on the repair site once the container is full. Furthermore, the repair could only be attempted on one side of the container. Saving and reusing rainwater on our allotment is important, but simply replacing the IBC was not an attractive option, being expensive, time consuming and bad for the environment.

First we prepared the site of the repair by ensuring it was dry, giving it a quick clean-up, and scratching the surrounding area with scissors to help the SUGRU adhere better.

We worked some SUGRU for a few moments until it was soft and malleable and used it to patch the entire area surrounding the crack. We were generous with the SUGRU, taking into account the pressure that 1000l of water will exert on the repair once completed.

After a day or two to cure, the repair is complete. Our IBC is once again in service storing rainwater on our allotment, saving water, plastic and money!
