Base
You need a base for your greenhouse to ensure that it is level and rigid. To save time and trouble in laying a
traditional brick or concrete base, Halls can supply a simple-to-assemble prefabricated base as an optional extra.
However, if you want to make your own base you should make it to the dimensions in fig. 3
. It is most
important that the base is square and level so check that its diagonal measurements are equal as in
fig. 1
and
that the angle between the wall and the base is 90
ᵒ
as in
fig. 2
. Tanalised timber packing of not less than
12mm
thickness and not more than
30mm
width should be made to fit the aluminium section, as shown in
fig. 2a
.
When the greenhouse has been assembled, it can be screwed to the base with no. 12 screws and rawlbolts (not
supplied) through the sill bar (not pre-drilled) in
fig. 2a
.
IMPORTANT
If you wish to erect your greenhouse on a solid concrete plinth, you should follow the outside dimensions in
fig.
3
. However it is important to avoid any possibility of water seeping under the base forming puddles. You should
ensure that the base slopes down towards the outside of the greenhouse. The timber packing will have to be
suitably tapered.
N.B.
These diagrams are only if you are building your own base as opposed to buying the
prefabricated optional base, which is the easiest option.
