Membrane Seals - Trelleborg Marine and Infrastructure

Membrane Seals - Thumbnail

Overview


There are a wide range of membrane seals for different applications such as omega joints and water-stops that secure the gap by fixing the seal on both sides of the opening.

Large dams worldwide, have gates within the structure to assist in controlling water flow, the effectiveness of these gates is largely determined by the performance of the rubber hydraulic seals. Trelleborg seals are available in a variety of rubber compounds and can be supplied with Kevlar® reinforcement, fabric reinforcement or PTFE coatings. 

Trelleborg Marine and Infrastructure has a quality system certified to ISO9001- 2000 and are committed to supplying high quality, durable products which conform to the customer’s specified requirements and operating conditions. To ensure superior construction, all corner sections of seals are usually fully molded with any vulcanized joints being in the less stressed straight sections. Trelleborg will design and manufacture rubber seals to meet your unique requirements. The brochure provides technical aspects of rubber hydraulic seals for dams and tunnels, and an extensive profile listing of our Seals. 

As a result of thermal expansion, creep, shrinkage and traffic loading measurements of constructions can vary. To make this movement possible, several joints can be implemented. The dimensions of the joints vary. To create a flat joint at all times and prevent leakage, a expansion joint is applied. Examples where expansion joints are used are; bridges, viaducts, concrete road surfaces, airfield runways and the inner site of tunnels. The expansion joint can be used in old as well in new constructions.
