b) Installing into concrete
Procedure

Create a compact underlying layer of gravel 150–300 mm thick. This can be regarded as the thermal
insulation.

Place the heating cable in an open-looping pattern on the reinforcing grid and fix it with fastening
strips. The heating cable must not be too tightly affixed or it could be damaged due to the thermal
expansion of the concrete.

Place the reinforcing grid in the middle, and at maximum 2/3 down into the concrete layer.

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 cable with a concrete layer. The concrete layer must be monolithic so that individual layers
do not separate due to thermal stress.

Measure the resistance of the heating circuit and the insulation resistance again and record the
measured values in the certificate of warranty.

The concrete mixtures must contain ingredients protecting it against external effects.
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.

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.
