Ground Screws for Decking & Garden Room Subframes
THE MIGHTY MOLE is a large (700 X 65 mm) galvanised steel foundation screw that simply screws into the ground, to the level you require, so that your decking subframe has a dry , strong, level surface to sit on.
The Mighty Mole Ground Screw, top (Hat) and tool is manufactured specifically for adaptability and ease when building decking and garden room subframes.
Traditionally............
when installing a decking subframe onto soft and /or uneven ground 4x4 posts would be secured in the ground so the subframe is kept off the ground and to make a dry , safe, level base for decking. In order to secure these timber posts in the ground you would have to
-
dig holes at least 3 x foot deep every metre (on a 3 M x 3M deck you may have to dig 9 x holes)
-
cut these large heavy posts to size
-
mix concrete and pour into every hole under and around every post
-
ensure they are straight before the mix goes hard
-
wait for it to go hard
-
attach the subframe to the posts
-
cut off any raised areas
