Installing into concrete
c) Installing into fine washed sand
Procedure (suitable only for use under pedestrian sidewalks)

Create a compact underlying layer of gravel 150–300 mm thick. This can be regarded as the thermal
insulation. You can find information about the effect and importance of high quality thermal insulation
(e.g. on the basis of extruded polystyrene) on the FENIX internet pages – category
ECOFLOOR/Outdoor applications, or you can consult a technician regarding its use.

Cover the gravel layer with compact sand 5 cm thick.

Place the heating cable in an open-looping pattern in accordance with the required output. Use Grufast
fastening strips to fix the cable.

Measure the resistance of the heating circuit and the insulation resistance and record the measured
values in the certificate of warranty.

Draw the scheme of the heating cable layout in the certificate of warranty.

Cover the heating cable with a 5 cm layer of sand, then place the tiles.

Measure the resistance of the heating circuit and the insulation resistance again and record the
measured values in the certificate of warranty.
