Because the foundation earther longer has contact
with the earth here, additional grid ring earther
must created.
To ensure contact with the earth, water-impermeable
concrete must not used.4 Perimeter insulation
Perimeter insulation heat insulation, which sur-
rounds the area the structure contact with the
earth from outside. The founda-
tion earther can implemented the concrete.
If the exterior walls and the foundation plate are sur-
rounded with perimeter insulation, the earther the
floor plate still has some earthing effect the strip
foundation open the bottom.
If the building structure surrounded all sides by
perimeter insulation, i.
If the perimeter insulation only the surrounding
walls, earther contact often still intact.e. all surrounding walls, strip
foundations and the bottom the foundation, the
function the foundation earther longer fulfilled.
