• Further studded strips the exterior walls produce
a very strong electrical insulating effect.
• However, earthing resistance usually still suffi-
cient.
Studded plastic strips
• Made special, high-density polyethylene. the in-
dividual membranes overlap, the earth contact of
the foundation earther impaired.
"Simple" films:
• With simple films, the foundation earther effect is
limited.
Because the foundation earther longer has contact
with the earth here, additional grid ring earther
must created. this case
the earth contact the foundation earther no
longer intact. The foundation earther effective an
earther the strip foundation the foundation
plate.
