The substrate must be solid, cleaned from crumbling particles of paint, rust, cement laitance and other substances which decrease adhesion. Surface with strong roughness subsequently tend to pass water. We recommend you to smooth freshly poured concrete rail in those places where will be placed the cord.

The tape should be fastened to the surface between the inner and outer valve using 4-5 of liquid nails on the meter or mastic. All profiles should be tightly in contact to ensure a quality connection. Connect the cords together should butt-to-butt.


  • Avoid applying heavy rain.
  • After installation, the surface must be protected from moisture prior to pouring concrete.
