  1. C.C. LINING By M.S. CHALAPATHI RAO

  2. FUNCTIONS OF LINING (IS: 10430 : 2000) • Minimum seepage loss • Increased hydraulic efficiency • Increased resistance to erosion/ abrasion • Prevention of water logging • Reduction in cross section area and consequential smaller structures

  3. TYPES OF LINING • Rigid lining:- • Cement concrete lining • Pre-cast cement concrete lining • Brick lining • Tile lining • Soil-cement lining • Napa slab lining • Cement mortar lining • Flexible lining:- • LDPE lining • HDPE lining • Asphaltic membrane lining • Poly-felt lining

  4. STAGES IN LINING • Construction of templates/ model walls/ profile walls • Sub-grade preparation • Drainage arrangements • Production of concrete mix • Placement & compaction • Providing of joints

  5. METHODS OF LINING • Manual lining • Pavers lining • Pre-cast slab lining

  6. INDIAN STANDARDS FOR CANALS LINING • IS: 456-2000 • IS: 3873-1993 • IS: 4558-1998 • IS: 5256-1992 • IS: 9451-1994 • IS: 7245-1974 • IS: 10430-2000
