In-building drain stack and water supply rehabilitation — minimal disruption to occupants
Aging plumbing in residential, commercial, and institutional buildings often suffers from corrosion, leaks, and reduced flow capacity. Trenchless CIPP rehabilitation restores drain stacks and pressure water lines without demolishing walls, ceilings, or floors — a transformative solution for occupied buildings.
Different damage profiles, host materials, and operating conditions require different rehabilitation approaches. Here are the methods best suited for this application sector.
Inversion CIPP using vinyl ester resin and dry felt tube handles building drain stacks from DN50 upward. The flexibility of resin-impregnated hose pre-cure allows it to fill cracks, bridge gaps, and navigate around the bends typical of building plumbing geometry.
Pressure-rated flexible reinforced tube with PE/TPU coating rehabilitates building water supply lines while remaining compliant with potable water sanitary standards. Ambient-temperature service from 0°C to 40°C covers all typical building water applications.
