LINER
**************************************************************************
NOTE: This specification covers rubber and plastic
liners. Plastic liners include polyethylene,
ethylene copolymer, chlorosulfonated polyethylene,
and poly (vinyl) chloride material. Allow use of as
many of the above types of materials as design
considerations allow. Such considerations include
cost, foundation conditions, chemical compatibility
between liner and stored product. Fabric reinforced
liners are available and are useful where extra
strength is needed. Do not use the extra strength
of fabric reinforcement as a replacement for an
appropriate thickness of subgrade or base.
**************************************************************************

Unsupported Plastic
ASTM D 3020 or ASTM D 3083, [_____] mm mils thick.
2.1.2
Supported Plastic
ASTM D 3020 or ASTM D 3083, [_____] mm mils thick, in plies with the center
ply being a fabric scrim of [6 by 6, 0.111 g per meter] [6 by 6, 1000
denier] [8 by 8, 0.028 g per meter] [8 by 8, 250 denier] [10 by 10, 0.111 g
per meter] [10 by 10, 1000 denier]polyester.
2.1.3
Chlorosulfonated Polyethylene Synthetic Rubber (CSPE)
**************************************************************************
NOTE: This paragraph is for one type of
chlorosulfonated polyethylene (the generic name for
the material "Hypalon," a Dupont trademark)
synthetic rubber liner. As properties vary with
thickness and amount of fabric reinforcement,
modifications to this specification will be required
if design requirements are different. Assure that
modifications do not result in proprietary
specifications.
