Points of making a basement:
Ś
Host unit basement should be made in strong concrete ground,
See Fig 3.6 for common practice or start after field measurement
ś
The basement should be completely horizontal and make sure all
the contactors can contact symmetrically.
Ŝ
Ensure the the basement supports the vertical foldings of the front
and back bottom plates directly, since its the actual bearing place.
ŝ
Macadam base is unnecessary. But cocrete surface should be
roughed. The proportions used in mixing the concrete should be
cement 1/sand 2/ pebble 4, including ĭ10reinforced rebar. Even
the surface of concrete. The edge of the basement should be
chamfered.
Ş
Drainage ditch should be arranged around the basement in order
to drainage water around the unit.
ş
Please check endurance of the roof to ensure loading capacity
could bear the weight.
