What is the GroundPlug® Easy Mounting SystemTM?

The GroundPlug® Easy Mounting SystemTM is a no-dig, no-pour screw pile footing alternative for your outdoor building projects. The GroundPlug® Easy Mounting SystemTM is based on the GroundPlug® TwisterTM screw pile footings that come in different size variations to suit your project. The screw pile footings are super easy to work with and can be screwed into the ground in minutes with common tools like an impact wrench, or a hand tool with socket wrench if you are just installing a few.

How do I use the GroundPlug® TwisterTM as footing?

Once you have placed and aligned the support beams of your shed, deck, carport, pergola, cabin, garden swing, playhouse, trampoline or whatever home improvement project that needs a solid, durable foundation, the GroundPlug® TwisterTM screw pile footings are easily driven into the ground and mounted to the beams with the supplied bracket, bolt and screws. After this all supports placed for alignment can be removed.

How do I decide which size GroundPlug® TwisterTM footing to use?

The GroundPlug® TwisterTM footings come in 3 different thread diameters: M10, M12 and M16 measuring accordingly: 10 mm, 12 mm and 16 mm in diameter. Each variation comes in a numbers of lengths with respective Extenders.

What happens if there is a rock in the ground?

The GroundPlug® TwisterTM screw pile footings are actually much easier to work with in rocky ground than concrete footings. First of all, you wont first find out about a problem rock once you have already done all the digging. It takes just 20-30 seconds to screw in the screw pile and discover, that there is a rock in the way. Then you have 2 options:

Easiest solution is to just move the  screw pile placement slightly to one side. Alternatively if the rock problem is larger than what you  can move the footing, you can dig out the rock before installing your GroundPlug® TwisterTM.

There is also the option to drill through the rock if possible. In this case you will need to pour some concrete to support the screwpile footing. Since the spiral will not have any grip in the rock section.

 

Are the GroundPlug® TwisterTM screw piles affected by frost?

We have many years of experience mounting our steel footings for the railway and highway industry in Scandinavia, working in conditions of hard frost. The design of our products is adapted to cope with tough conditions and our GroundPlug® TwisterTM screw pile footings are especially developed for use in frosty climates.

When speaking of frost. If you consider your structure to be sensitive to even minimal displacement. You should choose a length of your screw pile that will reach into frost free ground – which will depend on geographic location.

Do you use the same calculations as for a concrete block?

The GroundPlug® TwisterTM footings can handle the same loads as equivalent concrete footings. What you need to ensure is that you select the correct  GroundPlug® TwisterTM footing size for your project and soil conditions.

Here you can see a chart that should give you some indication of which GroundPlug® TwisterTM screw pile footing to choose for you project.

Is the GroundPlug® Easy Mounting SystemTM a more expensive solution?
