Sloping ground
Carry out the excavation so the base platform is in a hard
area.
In these cases, it is essential that rainwater from the higher
ground be channelled, in order to prevent a gap from
forming under the building.
If there are any doubts concerning this subsequent
channelling, it is best to use a mixture of sand and cement
when levelling.
Once the boards are level, use the levelling board to check
that the ground is in perfect condition.
