Waterproof concrete pipe penetration with puddle flange

LORO offers special pipe penetrations with puddle flange for waterproof (WU) concrete. Especially during on-site concreting, penetrations with puddle flange provide increased safety, as WU concrete usually has no additional waterproofing layer and any penetrating seepage water is stopped by the circumferential puddle flange.

The new roof and wall penetration with integrated thermal insulation for waterproof concrete roofs offers a factory-fitted insulation layer, so that cold water (for internal flat roof drainage) or cold air (for ventilation) is retained in the media-carrying inner pipe. Following the principle of the proven LORO-X composite pipes, the space between the media-carrying inner pipe and the outer pipe equipped with puddle flange is filled with an insulating layer of 2K PU foam at the factory.

Advantages

- Direct installation, therefore no recesses required
- Stable outer pipe made of hot-dip galvanised steel
- Very good component bonding due to identical expansion of concrete and steel
- Many years of experience
