3. FOUNDATION TUBES: Option C – Concreted Foundation Tubes – Recommended Method (Suitable for
base rail or trenched polythene)
1 Set two string lines to the width of the polytunnel
(10ft apart). Ensure they are parallel.
Tip! It’s best to put your polytunnel on a flat, level site.
A fall lengthways is easy to accommodate. A fall
sideways should be limited to about 6” over the
width of the polytunnel.
2 Set another string line for the end of the polytunnel.
Ensure the “end” string line is perpendicular to the
“length” string lines.
3 Mark the ground at each foundation position, to the outside of the “length” string lines at 5ft centres
until the full length is reached.
4 Temporarily remove the string lines so they don’t get in the way whilst digging.
5 Dig a hole for each Foundation Tube, approximately 25cm square x 35cm deep.
6 Reinstate the string lines.
7 Fill the excavated holes with freshly-mixed concrete.
8 Put a steel rod through the hole in the foundation tube. Slot the Foundation Tubes into the concrete, to
the outside of the string lines. Make sure the Foundation Tubes are vertical, touching the string line and
spaced at 5ft centres. The Foundation Tubes should be protruding above ground by approximately 40cm.
Tip! Allow the concrete to set before you try to install
the framework!
