2.6.2. Groundwater infiltration
Where there is heavy groundwater infiltration and the pipe has a rough surface structure, we recommend
always
using an additional hydrophilic waterstop affixed to the rubber gasket to ensure a tight seal.
Always use a hydrophilic waterstop if you are not certain that the circumferential seal is
sufficiently thick for sealing.
On badly corroded surfaces of host pipes, especially concrete pipes, a hydrophilic waterstop must
always be used.
Attaching a hydrophilic waterstop
Only use a waterstop recommended by the
manufacturer.
Stretch the waterstop to tear the layer that protects it
against premature expansion.
Cut the waterstop to length so that it will form a tight
seal around the gasket.
Glue the ends of the waterstop together with
superglue.
Pull the waterstop seal rings you have
made over each pair of circumferential
seals, making sure they fit snugly.
Pull the waterstop seal rings up to the
inside of the pairs of circumferential
seals.
Glue the waterstop to the rubber gasket
all the way round.
Note:
The waterstop seals add to the amount of material to
be compressed.
Increase the application pressure by approx. 7 psi (0.5 bar)
