Attaching the Staircase:
You will need 1 bag of Post-Crete (already mentioned earlier) for concreting the bottom of
the stairs and handrail posts. You will find it easier to only fit the top, middle and bottom tread to
the stair string at first. When you have fitted the handrails and posts , at the end of this section you
can then finish fitting the remaining treads, This makes the staircase lighter to lift wile fitting to the
tower.
You are now ready to fit the staircase. You have two more holes to dig for the bottom of the
stairs and the handrail posts. Follow the dimensions on the following pages. If the sides of the stairs
are going into the ground by more that 300mm you may wish to cut the excess off. Ensure you cust
the bottom and NOT the top of the stairs. Pile your soil onto a piece of plastic to minimise clearing
up afterwards.
