a basement "goes up"

the substructure

- ducts and drains -
- gravel bed -
- dpc -
- insulation -

is prepared

the ground
slab is in

preparational work
before the elements
arrive

at the road's edge a
rain water cistern
and the connection
to the public sewage
system are installed


back

the first wall goes up

the segments are prefabricated in a
factory like
environment

including precisly
custom-designed
and custom-built
steel reinforcement

the wall segments
are hollow


to be filled with
concrete...
a little later

basements usually
feature
doors,
windows,
staircase(s),
ducts and recesses;

all those items were
part of the plans;
hence, they are
incorporated
into all segments
before the
segments have been manufactured
and long before
they are joined
on site

...
next part, please
...

it is a bit like
playing with
oversized Lego

please note
the steel pins

they will interlink the
wall segments and the
foundation slab

grey = solid concrete fill

all segments
...

...
assembled
to

...
begin laying
the ceiling
elements



back

those include
steel mesh
and distancers
...

...
and have very
precisely
been prefabricated
to plan in a
factory
like environment

so assembling on site
is a piece of cake
...

...
and just a matter
of a couple of hours



back

more mesh
...

...
and shuttering
where necessary
...

...
before concrete
is pumped into
...



back

the wall
segments

compacted

the ceiling,
or rather the
foundation slab
is casted

...
and
levelled off
...

...
to perfection!
