Guroflex, an environmentally friendly two-component joint filler


Guroflex is an environmentally friendly, easy-to-use, bicarbonate-based, two-component filler that does not require heat treatment. It can be used for all types of underground cables up to 1 kV, i.e. XLPE, PE, PVC, and oil-paper insulated cables. Guroflex has excellent insulating properties, is hydrophobic, and provides reliable corrosion protection. No special protective equipment is required when working with Guroflex. It can also be installed at low temperatures.


The filler is supplied in two-chamber packs or cans. Just before it is poured into the sleeve, the two components are mixed and a change in the molecular structure of the material is initiated by the formation of cross-links. The mixed aggregate can be stored for 3-4 minutes. The sleeve can be buried in the trench immediately after filling with Guroflex.
