A 400 g/m² protective slip layer.
A polypropylene based fleece with a polyethylene backing, for use as a protective and/ or slip layer. It may also be used as a protection sheet under reused bitumen-contaminated gravel ballast.
UV stabilised Sarnafil Type GK can be left exposed to weathering.
Sarnafil Type GK is loose laid, but the 50 mm side and end laps must be sealed with adhesive tape, to ensure that slurry does not penetrate the felt at the edges, damaging the polyethylene film backing.
