 The cables are normally covered by 2 inches of concrete. A thicker surface may be required
depending on the pour and application.
Make sure that the free cable is fastened at intervals of minimum 3' (45 cm), as the

concrete might move the cable when it is poured.
The concrete mixture must not contain sharp stones as these may damage the cable.

 The concrete should be allowed to set for 30 days before the heating cables are turned on.
It is not recommended for the GX mat or cable to cross an expansion joint.
