Concrete Bases for Conservatories - The Traditional Approach

While we  recommend steel bases, Brittany Conservatories appreciates that a number of
its visitors will be interested in a more traditional approach to constructing bases for
Conservatories and Sun Lounges.

For those visitors we are pleased to include some information on concrete bases for
conservatories

What is the specification for the base? How do I put the conservatory together? Can you
give my builder a guide?

TYPICAL BASE CONSTRUCTION SECTIONS.

Note - these sectional drawings are just typical sections - you or your builder supplier may
use different sections depending on site circumstances.
Example 1
With example 1 we have a fairly
typical section for the
construction of a base and dwarf
wall. This assumes that the site is
reasonably level and without any
major difficulties. As an example
of a variation on the above - note
that many suppliers prefer to
"sit" the inside of the
conservatory frame flush with
the inside of the external course
of brickwork.
Example 2

We again have a fairly typical
example based on a site without many
difficulties. Also your builder may
create a brick faced base rather
than concrete faced base. In our
example the conservatory Frame
rests on top of a damp proof
membrane. This is often used when
using timber frames. However with
PVCu frames it is more likely your
builder will lay The PVCu frames
directly down on foundation. (PVCu is
after all a damp proof material). The
usual finish then is to "lap" the
membrane that's under the concrete
floor up against the frame on the
inside.
Example 3
This shows a suspended floor detail
often used where there is a
significant difference in levels
between the ground level and the
finished floor level (FFL) of the
conservatory. Note an air brick
should be inserted at front.
Example 4

We have a good example of one way
to overcome a large variation
between levels. You should
remember with examples like this to
allow for brick steps (plus other
landscaping) in order to safely "step
down" from your conservatory to the
ground level.
