Waterproofing of digester concrete with polyurea.

This digester tank concrete presented big cracks that passed through increasing when the tank was full.
This situation situation caused important leakages. For these reasons it was decided to waterproof with polyurea resines for the refurbishment of the tank and due to fact that polyurea has excellent properties of wear resistance, elasticity and durability.
