Ty-wrap 1 1/4” PVC Pipe to the top of the rebar in
the size and configuration of the loop (i.e. 4ft x 8ft).
Then ty-wrap the loop to the top of the PVC frame.
This stabilizes the loop during the pour and
separates it from the rebar.
Saw Cut Existing Surface
Cut “ deep into the existing surface, place a 45° cut
at the corners to prevent sharp edges from
damaging the loop wire. Notch out for the ”T”
connection where the lead wire connects to the
loop. Remove all debris from the finished cut with
compressed air. Place the loop into the saw cut.
Place backer material into the saw cut over the
loop wire and pack tightly. Place a high quality
sealer over the saw cut to seal the surface.
Resurface Asphalt
Saw cut the existing surface 3/4” deep and place a
45° cut at the corners to prevent sharp edges from
damaging the loop wire. Remove all debris from
the finished cut with compressed air. Place sand
over the loop wire to the surface and pack tightly.
Lay new asphalt.
