TEFOND is a high-density extruded polyethylene (HDPE) membrane with a single mechanical joint.Tefond is the ideal solution for all protection problems.

Why is TEFOND is the ideal solution to protect underground walls and foundations,which have already been waterproofed?

Because TEFOND is a perfect anti root barrier and because it protects the bituminous sheath.

Because HDPE makes TEFOND resistent to all chemical agents usually present in the soil and in building materials.

Because due to its special structural characteristics,TEFOND is highly resistant to impacts and to the mechanical stress coused by the compression of the backfilling: in this way it prevents damages to the bituminous sheath.

TEFOND is an ideal solution in renovation or remedial works where the protection of floors is required. By using TEFOND as an isolating membrane you may reduce the floor thickness and therefore the costs.Installing TEFOND with studs laid downwards will create an air chamber below the floor allowing the evaporation of moisture and preventing dampness.

Due to the studs characterising its surface,TEFOND ensures an excellent acoustic insulation.Tests show that its installation on floors reduces impact sound transmission by approximately 14 dB at a 500 Hz frequency.
