Single-pass linings are rapidly gaining favour and can now be achieved to a high standard of construction and finish using precast segmental, or sprayed concrete.
Sprayed concrete
is the only method of tunnel lining support that forms an immediate and intimate
bond with the strata that interacts actively with the ground surface instead
of passively requiring the ground to move before it begins to resist that
movement. A properly applied sprayed concrete lining is equivalent in strength,
impermeability and durability to conventional cast in place concrete, and
is often better in terms of compaction.
