Concrete Bases for Conservatories - The Traditional Approach
While we encourage and recommend steel bases, Conservatory-Base.com
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/conservatory
supplier may use different sections depending on site circumstances.
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. In our example the frame has been fitted slightly forward of the inside
edge of the external course of brickwork in order to facilitate an easier fixing for the
internal window board. Either method is OK in our opinion.
We again have a fairly typical example based on a site without
many difficulties. As previous you may find that your supplier
will fit the frame flush with the inside edge of the foundation. 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.
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.
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.
