5 steps to fasten the ground screw
Preliminary, let the property owner / customer sign the foundation installation conditions (see
page 8) and archive it legally.
1.
Step 1: Removal and primary drilling
Remove paving and gravel until a depth of approximately 15 cm. Use a ø 40 mm drill for
the vertical predrill. Pay attention to the chapter “Placing the ground screw“.
2.
Step 2: Preparation
For preparation for the 2 m ground screw a smaller ground screw, about 1.2 m long, must
be screwed-in and out again.
3.
Step 3: Screwing-in
Screw-in the 2 m ground screw until there is a space of 19 mm between top of terrace and
top of ground screw. This ensures the winter coverage will be even with the ground. In
case of multiple parasols use an optical level to have all ground screws screwed-in to the
same depth.
