BUPOLSA's double-walled tanks are designed in glass-fibre reinforced polyester (GRP) for the storage of all types of substances.

BUPOLSA has the patent 2644 of double wall tanks for the storage of hydrocarbons, having been taken as a reference model for many other manufacturers.

The double wall tanks have an interstitial space between the two walls. They are designed to avoid spills and consequently the contamination of the subsoil.
