Our specially designed music note seals, hump seals and flat seals are designed to provide hydraulic sealing for water infrastructure engineering applications
Trelleborg's custom hydraulic seals are commonly used to seal and ensure water tightness of construction joints for dams, tunnels and any structure subjected to intense pressure. They are commonly utilised in dam gates, dam wall extensions, tunnels and concrete slab joints. These water stops may also be used to prevent product leakage from a tank or structure into the adjacent environment.
Seals can be offered with or without PTFE contact facings which enhance slippage and prevent sticking to adjacent contact surfaces.
