In the underground of Doha, Qatar, there were leakages coming through the walls and ceilings of the tunnels. In most tunnel constructions there is a waterproofing membrane installed behind the concrete structure. When a leakage occurs, injection is required. In civil engineering this is called compartment membrane injection. On demand for this specific inquiry from our partner, Tradecc has developed the PC 509 ZL Acryl to water seal the tunnel. This acrylic gel is compatible with the membrane.
