The importance of carrying out bearing and expansion joint inspections by proficient and competent engineers who understand their functionality can often be key to maximising a structure’s lifespan and avoiding major, unexpected, emergency repair costs.
USL Ekspan have carried out a number of projects for swing bridges and foot bridges. From design, fabrication of all structural components, to trial erection and final installation. Details of these type of bridge installations can be supplied on request.
The ES seal, originally designed for immersed tunnels as a secondary seal, is a robust, flexible, reinforced omega shaped rubber seal used in various applications.
It is an ideal solution for joints where gap movements can be expected as a result of temperature effects and/or settlements. The unique property of the ES seal enables it to withstand high water pressure in combination with large movements in all directions.
Based upon materials data, ES seals have a projected life in excess of 100 years. The operating temperature should be within -30°C and +70°C and the rubber should not come into contact with hazardous materials, such as oil.
