Case study: oil resistant fibreglass bund lining for an upmarket snacks manufacturer

The client

One of our clients makes upmarket potato snacks from high quality ingredients – and it needs to use lots of oil to make its products on a large enough scale.

The problem – a leaking bund

The only problem was that the company had a leaking bund, which would have caused major problems if sunflower oil or rapeseed oil had emptied into it.

So they came to us and asked whether we could help get their bund oil-tight once again – they only wanted to worry about making great snacks.

The solution – a fibreglass lining

The clients' bund is 9 metres by 8 metres, and over a metre high.

A long lasting solution was needed, so we recommended a fibreglass bund lining.

Fibreglass is strong, flexible and has a much longer lifespan than other coatings or linings – a good 20+ years.

Extra quick bund repair

We lined the bund in under a week and caused no disruption to the company's normal activities.

And now the work's done, they're free to concentrate on making their snacks – and won't have to worry about that problem bund for at least a couple of decades.

Rapeseed oil had leaked into the bund. It's not easy to clean up, so we used special caustic cleaners to get rid of it. Then it was time to send in an operative with a pressure washer to get the bund clean and ready for gritblasting.

Next came the gritblasting itself. This is necessary to give the brick and concrete a keyed surface – this makes sure that the fibreglass bund lining adheres to the surface properly, giving it maximum strength and adhesion.

With a nicely prepared surface to work with, it was time to apply the lining to the bund. First came a resin primer, followed by a chopped strand glass fibre mat, impregnated with resin.

With the re-inforced resin in place, the last job was to use orbital sanders to remove any irregularities, before covering with a further coat followed by a top coat to make sure every surface in the bund was oil tight.
