Selection of the adequate lining systems for each specific application requires a knowledge of materials, installation techniques and availability of design alternatives.

Performance of materials and their interaction in composite multilayered applications and desiccation cracking of the clay layers underneath geomembranes are studied.

The design needs to meet all of the needs of the user/owner. The lining system must be practical, constructable and functional. The quality assurance function, therefore, should start at the design stage. The design should be reviewed for constructability by material supplier and/or installer as a checking function to ensure problems won't arise during construction. This participation contributes to the successful construction of the lining system and helps ensure that the intent of the design is met.
