The minimally invasive aspect of our injection system is ideal for pipe penetrations. We drill very few holes and do not need to use packers or leave them in the wall, allowing another path for water to reappear. Our DifGel HD 2.0 Acrylic Resin is perfect for the tight spaces and movement that occurs with pipe penetrations. Since the injected gel never fully hardens, it allows for expansion and contraction during temperature changes as well as allowing us to reinject and build up the waterproof membrane as needed.
