Hydrophilic Gaskets

FAMA offers a range of customizable hydrophilic gaskets, designed according to different functional techniques.
The hydrophilic profile must be tested with ground water.

SWELLING GASKET
For abnormal GAPS recovery

Swelling gasket

UG035 26X11

The contact surface bulge is suitable for supporting abnormal GAPS.

Contact surface swelling is suitable for compressing gaskets after ashlar installation, reducing gaps.

CHEMICAL PROTECTION SYSTEM
For the integration of protective film at the tunnel soffit.

Sealing of joints with PEHD film is normally done by overlapping PEHD heat-sealed strips in place.

The solution devised by FAMA makes it possible to eliminate this time-consuming and expensive operation by adopting a special gasket with multiple integrated solutions:

  • The gasket is anchored to the concrete.
  • The gasket integrates the PVC film to itself, ensuring its sealing.
  • The gasket can integrate a hydro-expansive bead, creating the second sealing barrier.

GASKET PROTECTION SHIELD
For highly aggressive environments

UG043 44X26

The Gasket Protection Shield consists of two coupled profiles suitable for anchoring to concrete.
The outer profile is manufactured from materials suitable for withstanding extreme situations.
The inner profile is produced from materials with high conservation of elastic energy.

CONFINEMENT GASKET
With a double barrier

For projects where a double gasket is required at both the extrados and intrados, FAMA uses the anchored confinement gasket that prevents the propagation of any water infiltration inside the lining due to the channeling of the double gasket.
