In this project in Tel Aviv, Israel, our partner has used the PC Injectra hose system to waterproof construction joints. This is a worldwide known waterproofing technique which differs from the standard swell strips. This kind of injection hose system can be injected afterwards when it is installed or when the leakage occurs. For multiple reinjections, the PC 509 ZL Acryl is recommended. For one single injection, to make the construction watertight, the PC Leakinject 2K Flex 6811 LV is perfect.
