Some elastomers, polyurethane or polyureas, can be very successfully used for lining containers. We refer, for example, to the protection of the soil against possible infiltrations due to leakage from industrial plants. A non-fabric fabric can be laid beneath seeping containers, which can then be sprayed with an elastomer with suitable resistance to polluting products.

Elastomer coatings can also be very successfully used to waterproof the bottom of artificial lakes, with suitable attention paid to the choice of product, since certain polyurethanes or polyureas are subject to hydrolysis.

The bottom of rubbish dumps, collection reservoirs and waste water tanks are also potential cases for excellent applications.
