To increase the durability of reinforced concrete Dams & bridges, all concrete movement and construction joints, plus the bridge decks must be waterproofed to prevent serious damage to the concrete, or to the embedded steel reinforcement. Due to dynamic loading, the bridge decks must be protected with elastic, crack-bridging systems to accommodate any movement and maintain the protection. There are different technologies to repair the concrete face of the dam but one of the most reliable and economical is the application of a waterproofing geomembrane. The choice of geomembrane and the way of fixation for the waterproofing system is a very important issue to receive a long-lasting water tightness of the dam.
