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.
