BUILDING A BASE
When thinking about where the building and base is going to be constructed: Ensure that there will be access to all sides for maintenance work and
annual treatment.
TYPES OF BASE
- Concrete 75mm laid on top of 75mm hard-core.
- Slabs laid on 50mm of sharp sand.
Ensure the base is level and is built on firm ground, to prevent distortion. Refer to diagrams for the base dimensions, The base should be slightly
smaller than the external measurement of the building, i.e. The cladding should overlap the base, creating a run off for water. It is also recommended
that the floor be at least 25mm above the surrounding ground level to avoid flooding.
Place Roof panels into position on top
of building using the slot at the top as
a guide. Ensure the overhang is at the
front and that the center roof purlin
fits inbetween the front and rear
gable.
Secure each panels with 10x40mm
screws per panel.

Place a facia block at the front and
back of each roof panel. Secure using
