Water-Stop Tie Rod, Pipe and Plug: What Do They Do?

In tanks, pools and other water-sensitive reinforced-concrete structures, the tie-rod passage can require a dedicated water-stop detail rather than a standard removable connection.

Water-Stop Tie-Rod Component

Water-stop components are used as part of special formwork tie details where water tightness is important.

Tie-Rod Pipe

A permanent tie-rod pipe can remain within the concrete and form part of the tie passage detail.

Tie-Rod Plug

Plugs are complementary elements used with tie-rod pipe systems. Standard and gasketed variants can be part of the product range.

Difference from a Standard Removable Tie Rod

In a removable tie system, the threaded rod can be withdrawn after stripping. Water-stop details can include components that remain within the concrete.
