Floor crossings
Floor crossings should be made leak-resistant and sound-
absorbent. If mastic asphalt is used to cover the floor, the pipe
sections located near the floor crossings must be protected
using a protection sleeve or heat insulating wrapping material.
Roof drainage pipes in living areas
Roof drainage pipes projected through living areas can be
installed as shown in the example opposite. The specific area
weight of the casting should be at least equal to the wall.
The use of condensation insulation is also recommended for
Wavin AS+, as installation is subject to a physical law, albeit
with a certain time lapse in comparison to metallic materials.
Thrust-resistant connection
Gravity drainage systems (for rain or waste water) can be
subject to both planned and unplanned pressure surges. If
Wavin AS+ or Wavin is used as a pressure line for
a pump station, for example, the resulting pressure surges
are planned. If an overloaded rainwater pipe is subject to
hydrostatic pressure, however, this counts as an unplanned
pressure surge.
For both types of pressure surge, the pipe fittings and groups
of fittings must be secured to prevent them from detaching.
The Wavin LKS clamp guarantees this for internal pressures
of up to 2 bar.
