Attaching the Staircase:
You will need 1 bag of post-crete (already mentioned earlier) for concreting the bottom of the stairs
and the 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 while fitting to the tower.
You are now ready to fir 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 than 300mm you may wish to cut the excess off. Ensure you cut the
bottom and NOT the top of the stairs. Pile your soil onto a piece of plastic to minimise clearing up
afterwards.
