Signaltape Installation Procedure 

It is recommended that Signaltape be buried 12 in (30 cm) or less below grade.  The minimum distance from the top of the pipeline should be 12 in (30 cm), with 24 in (60 cm) – 36 in. (90 cm) recommended as shown in figure 1.  

Each run of Signaltape must be overlapped by a minimum of 20 ft (6 m) or must be joined as shown below.

Joining Signaltape

Each section of Signaltape should be joined end to end for repair of damage or installation, if not overlapped by 20 ft. (6 m). Peel back the two layers of each end exposing the core material (figure 2), and tie together using a double fisherman’s knot as shown in figure 3.
