How To Install Timber Decking Without Digging Post Holes Or Pouring Concrete
If you are building a timber deck, small or large, and want to save hours of time - whether it’s your labor or someone else’s - wouldn’t it be great if you didn’t have to dig post-holes or pour concrete footings?
Thanks to a new “twist” on an old idea - now you don’t have to! Without pre-drilling, digging, augering, or concrete you can simply screw one of the new galvanised “ground screws” into the ground for a maintenance free footing that lasts 20-30 years.
Once the footing is screwed into the ground it is ready to take a load immediately. Nothing needs to cure or settle. Each screw takes approximately 5 minutes each to install by machine, 3 minutes to set-up and 2 minutes to drive home. So in 30 minutes you can have 6 footings installed, then immediately begin bolting in the bearers. Some even come with U saddles so that a 70, 90 or 110mm post can be bolted directly to the footing at the required height.
Look for ground screws that are galvanized to international standards, so they will easily outlast your timber decking. What’s more, if you decide to move or remove your timber deck you can simply unscrew the footings and re-use them for another project.
Similarly, if you accidentally put a footing in the wrong place you can simply unscrew it and move it where it needs to go. Try doing that with concrete!
Obviously, rocks will cause problems (whether you are using a ground screw or digging a hole), but other than that almost any soil is suitable to install a ground screw into, even sand.
