Some problems with the use of film materials for facing hydraulic structures

Conclusions

• 1. Watertight polymer films on earth structures are a progressive and economical means of protecting them against seepage.

• 2. The most important task of research is to establish the reliable and long-term operation of polymer film facings and diaphragms. For this purpose variants of film facings or diaphragms should be developed when designing structures requiring protection against seepage.

• 3. For facing high-head hydraulic structures it is necessary to set up the mass production of PE and butyl rubber films 0.4, 0.6, and 0.8 mm thick and sheets 1 and 2 mm thick.
