Types of lining in irrigation canals

Short answer

Cement concrete, shotcrete, brick, stone masonry, soil-cement, asphaltic, plastic (geomembrane), compacted earth, bentonite, and lime-based linings are typical. They are classed as hard-surface, earth, or buried membrane.

Enlist the various types of lining applied in irrigation canal.

Types of lining used in irrigation canals:

  1. Cement concrete lining (plain or reinforced, cast in situ or precast slabs) – the most common.
  2. Shotcrete (gunite) lining.
  3. Brick lining (single or double layer of bricks laid in cement mortar over a bed of lime/ cement mortar).
  4. Stone masonry / boulder lining (dry or cement-mortar, pitching).
  5. Soil-cement lining (a mixture of local soil and 6-10% cement, compacted).
  6. Asphaltic (bituminous) lining – asphalt concrete or buried membranes.
  7. Compacted earth / clay lining (tight soil or clay blanket) – low cost for small canals.
  8. Plastic (geomembrane) lining – low-density polyethylene film, covered with soil or concrete slabs.
  9. Bentonite lining.
  10. Lime-based / lime-concrete lining.

Linings are also classed as hard-surface (concrete, brick, stone), earth type (clay, soil-cement, compacted earth) and buried membrane types.
