A number of renowned independent institutes in several European countries have carried out extensive research into Trisoplast under the supervision of the relevant federal and local authorities. The results showed that Trisoplast has significantly better barrier properties in comparison with traditional barriers:

• Extremely low permeability
• Excellent self-healing ability
• Ability to cope with differential settlement due to high flexibility
• High slope stability and bearing capacity
• Gel formation prevents washing out
• High chemical and physical stability
• High moisture retention capability (high resistance to drying out)
• Low gas permeability
• High lifetime expectancy due to durability
