A drain is an element intended for local collection of water from the bridge insulation level. It is made of polyester laminate, reinforced with glass fibre. It offers resistance, which is not lower than in case of steel drains and even much higher chemical resistance.
Just like cornices, the SYTEC drains are used in the road-and-bridge building industry. Using the polyester laminate drains intended to drain bridge structures, make it possible to attain as high or even higher mechanical strength than in case of steel drains. An additional advantage of SYTEC drains is their increased chemical resistance compared to traditional steel.
