Cables can be ducted through the conduit opening in a random order. After ducting the cables, a RISE insert sleeve is applied around each cable. The remaining free space in the conduit is then filled with RISE empty sleeves. The insert sleeves are pushed into the conduit pipe in such a way as to leave 20 mm free space at the front (at both sides).

A 20 mm thick layer of FIWA sealant is then applied at each side of the conduit. Some overfill of the sealant is needed because some sealant will be pushed between and into the empty sleeves during finishing.

To add or remove cables in a later stage some of the FIWA sealant can be removed using a hollow punch.

After the cable or cables have been installed, the openings in the sealant layer are refilled at both sides of the penetration with FIWA sealant.

To smooth the surface, a cloth that is sprayed with water is used to press down the layer of FIWA. The FIWA sealant between the cables is pressed down and smoothed with a spatula or putty knife. When smoothing is finished a last check should be taken if sufficient sealant is applied in between the cables.
