Sleeve Base Set-up
These instructions assume normally packed soil. In case of lightly packed, sandy,
humid, or other conditions where concrete block could potentially shift, increase the hole
size to create a wider base for greater stability.
Poles are supplied with a PVC sleeve which
has a length equal to 10% of the height of
the pole and an internal diameter of 5" for
20-foot and 25-foot poles, and 6" for 30-,
35-, and 40-foot tall poles. A set of 4
shims is also supplied.
|| Dig a round hole based on dimensions
indicated in Drawing A. Pour 6" gravel at
the bottom of the hole to facilitate water
|| Position the PVC sleeve at the center of the
hole, its top flush with the ground level,
and secure it in such a way that it will
remain perfectly vertical and not move
when pouring concrete.
|| Fill in the hole with concrete around the
PVC sleeve, making sure that it stays
vertical, up to the top of the ground level.
Make sure not to pour any concrete into
the sleeve. While the concrete is still wet,
adjust the sleeve to ensure it is vertical.
Drying time varies with weather and
cement type. Allow one day for quick
setting cement and a full week for
|| Once the PVC sleeve is firmly secured in
the concrete, bring the pole's butt to the
sleeve's opening, lift it up and slide into the
sleeve. Adjust pole's positioning using the
shims provided. When pole is in final
position, pour sand in space between the
pole and the sleeve. Finally, seal the space
between the pole and the sleeve with
silicon caulk to keep the sand from getting
