For the use of the prefabricated foundation
proceed as follows:
1. For the prefabricated foundation, dig an
excavation pit with a minimum area of 100
x 80 cm and a minimum depth of 60 cm.
2. Make a compacted gravel bed.
3. Pull only one supply cable at a time
through the empty conduits in the prefa-
bricated foundation.
4. Bring the prefabricated foundation into
position so that the upper edge of the
foundation plate coincides with the top
edge of the finished floor.
5. Underlay the prefabricated foundation and
level the foundation with a spirit level.
3.4.2 Casting of an own foundation with foundation

2. Make a firm gravel bed.
3. Fix the foundation plate in the desired
position. The short ends of the threaded
rod stand vertically upwards. The upper
edge of the foundation plate corresponds
to the top edge of the finished floor.
4. Pull only one supply cable at a time
through the empty conduits.
5.
Insert the empty conduits about 5 cm
through the holes in the foundation plate
and fix the empty conduits.
6. Lay the empty conduits as required.
7. Align the foundation plate with the spirit
level.
8. Pour out the excavation pit so that the
concrete is in complete contact with the
underside of the foundation plate. The
upper side of the foundation plate must
not be covered with concrete.
